Thanks Adam, Simon and the rest of the Heat Geek Team, for bringing your hot water cylinder design to us and selecting our bespoke specification as the one which met all of the project’s requirements. So next time *you* encounter a project which may require a bespoke cylinder or buffer vessel, we'd always appreciate the opportunity to explore the options with you.
To be clear, we paid full price for this newark cylinder. There was no promotion.
Is there any reason I shouldn't just ask Newark to build me the exact same cylinder as yours to go with the Vaillant Arotherm Plus I'm planning to install?
A shout out to Terry ,fantastic engineer who I have dealt with over the last 12 years .Knows his stuff and overall a great guy !
As an owner of a heatpump on a flat roof, I can confirm, it fine these days. Can hear it in the utility underneath, but only when it's on the hot water cycle..
Hydrogen will definitely be a big thing in industry (like steelmaking), but yeah, it’s not going to be a thing in residential or commercial. Here in Australia the gas industry is still trying to push it as a last ditch effort to maintain some relevance and eek some money out of stranded assets, but it’s not going to happen. Those Vallient unit looks really nice. I have a 5kW Sanden for domestic hot water but I’d consider upgrading to one of those in a few years if I put in hydronic underfloor heating (pretty rare here) when I hopefully do an extension.
8:00 Not enough cylinder talk IMO.
More please 🤓
Great vid. I’m on the same path at the moment in my home although started with solar and battery and now have just bought an EV. Heat pump is on the list at some point, but my 4 year old boiler is still working fine and we don’t use a great deal of gas with it being a new house. Keep up the good work!
Great video. If you're adding a super high CoP hot water system and plan a battery then why the Eddie heating the hot water directly with electricity? Surely you can charge the battery off the solar and then heat the hot water via the heat pump at >>100% efficiency.
As per usual, brilliant video explaining all that can be done with a heat pump.
Its a shame that the boiler manufacturers and the government are still hyping on about heating homes with hydrogen instead of sorting out the electrical grid for electric heating.
Paul,
do you have any concept of what is required?
Increased generation capacity, increased transmission line capacity, increased local area network capacity for a heating system that will just be used for a couple of months a year at high output. This means that for much more of the year there will be underutilised expensive equipment lying idle.
The full implications of this heat pump mandate has not been thought out by the government.
@@iareid8255 its all about having a smart grid not how much power all at once, Germany is building the infrastructure to do this and its been happening for five years, whereas the UK hasn't even started yet.
Paul,
smart grids , sounds good but in reality tissue paper over severe fissures.
Have you seen the wind contribution to the U.K. grid for the last two months? Very low,
there is insufficient demand that can be removed to compensate.
Solar has been strong but of course it's average over the main demand period is small.
Nice to see Liam helping out..........Cant wait to see how you configure the system given you will have cheap electric time slots which may conflict with efficiency? please keep us updated👍
Cheap time slots are mainly for my battery, not my heat pump 😉
Not gone a full winter yet but very happy with my heat pump and solar set up just need to figure out how to get the heat pump to stay at 35degs otherwise it drains the battery to quickly (will hopefully sort with Liam before winter 🤞)
As you say low and slow
Mark is due to fit our heat pump next week! Very excited. Another Heat Geek assured installation. Hopefully it won't be as chaotic with as many engineers onsite. 😜
Unless your trying to do it in 1 day also, you'll be fine 🙂
@@HeatGeek Mark has sensible planned it over a number of days!
What rads are these? Apologies if this has been answered already! Also, is high volume water content good or bad for efficiency when running a heat pump?
Mark installed my heat pump last October and he made a superb job and I am really impressed with the performance of the heat pump with a current COP of 4.2
ASHP has left me in debt to ovo. and a wrecked house. Wait until winter comes, then you will hear it.
Loved to see this conversion, great job :) It is interesting to watch this from a German's perspective. My house is from 1968 and the population generally is of the opinion that houses (brick and mortar , roof insulated + big radiators and type 22 radiators) is generally not capable of using a heat pump.
Nice to see that others are doing what my plumber says is impossible 👍
Hi Adam, thanks for all the amazing content and everything you have contributed through the heatgeek organisation!...
I am now thinking more towards ashp as part of an ongoing extension - however, the most suitable place looks like a flat roof directly above garage/plant room. The other option is a fairly narrow passageway which could be an issue with air flow. Would you recommend the roof option for a 10kw pump and have any further thoughts on the potential airflow issues in narrow passageways - your video on this seemed to suggest it may not be that much of an impact on performance?
Thanks again 👍
Can you wall hang it above the flat roof? If the narrow walkway has good airflow and meets manufacturer clearances it won’t be a problem. Mines in a flat roof and can hear it when at -2 or below but fine above that!
@@HeatGeek thanks - no option to hang above flat roof as the roof is pitched in this area. Tbh, I am prioritising shorter / easier pipe runs with roof option but perhaps that's a false economy. I could put it in front of the garage alongside boundary but would need to route pipework and wiring under ground 🤔
I'd love to have that level of noise. My boiler is in the loft and is well loud in our bedroom in the winter.
Glad you're being clear about hydrogen, couldn't agree more
Great to see Tommy on your crack team! He installed our top notch 400%+ HP last year and did a superb job. Where you from? "Raaan cowna" 😂😂 12:25
It's 8:40 and current grid intensity is 165g CO2/KwH, not sure where 900g is coming from but it seems way off!
Any chance of a link to the radiators you have gone with? they look great.
So much good in the 1st 3 mins of this video... the 90% of homes point being SPOT ON!
so £7k to £14k for a heat pump plus all the extra and the squad of people on site this install would probs be top end of about £30 or £40k. on what planet do you think that that can compete with a gas boiler at £1600 takes a day to replace with 2 people. unless the price comes down for initial cost these systems aren't going to fly anywhere. Normal people are struggling to buy bread and dont have 14K for a heat pump. Although this was a very interesting video - I just put a new gas boiler in so possible in 10 to 15 years I will think about a heat pump.
Samsung 8kW heat pump is £2k.
First time I’ve come across a fuel cell CHP boiler but I was puzzled when you referred to it as a hydrogen boiler - it’s a bit of a misnomer really that was maybe to give brownie points to hydrogen even though it still uses gas albeit more efficiently- well done for admitting it is a waste of time even at great expense - the public should not be duped by lobbying from those with vested interests in hydrogen clinging on to the hope that gas can be replaced by something similar…
This guy is the Colin Furze of heating 😉
Are the radiators normal cast iron radiators? Could you please share the manufacture of the radiators so that we can compare the specs with standard radiators? Would this heat pump system work with UFH on the ground floor and cast iron radiators on the upper floors?
With my 350m3 of heated space (130sq meters) I use between 5-7m3 of gas daily. (hot water included)
Heating 24/7 at 22°
The Thermostat is on a heating curve of 0.7 and the water inside the radiators is from 36-40
Outside temperature between -2C° to+5°
The Vaillant boiler is oversized (24kw I think) so it doesn't modulate low enough.
Would go for a heat pump but just to lower emissions.
Amazing video, do you do your courses in person or only online as i struggle with online learning? Also what are the installation costs and running costs, compared to a gas boiler, thankyou
The hot water cylinder looks well designed…..maybe you should partner with them to release it as a heat geek branded/certified cylinder?
Great vid but why would you want that big metal ugly box on show most people can’t put them on a roof,wouldn’t want it round the back as well, I’ll stick to a boiler
How many plumbers does it take to install a heat pump. Lots apparently.
Great video Adam and the team :) Whats is Marks A/S/L by the way?
😂 I'll find out and get straight back to you!
Nice video! Have you got a link to the new radiators you used? I thought those cast iron radiators didn't have a good heat output rating, if they do I'd get some too.
I don't know why everyone seems to think this its strange. But they ALL absolutely do yes. They are from best heating.. I think best heating are great!
BBC R4 today interviewed Karl Arntzen, CEO Worcester Bosch discussed the roll out of ASHPs. Just one ninth of target. He blamed the "spark gap" the 3 to 1 difference between the cost of electricity compared to gas. Even with a COP of 3 at best energy bills will be more or less the same. So why would anyone choose to fit an expensive heat pump with no proof of long term savings?
Twins! And you managed to grow your business as well as you have!?
Legend
Well done you & Jo!
Hahaha that's amazing to notice! Yes and they have a sister only 1.5 years older too. I cannot describe the last 7 years of my life!
@@HeatGeek "challenging" I imagine
@@Lewis_Standing I will die relatively early
Very interested how you are getting on with the garage roof placement. Anything noteworthy in the last year of use?
I'm really interested to see how this plays out for you. We installed solar 2 years ago with batteries, then last year a mixergy tank and we haven't looked back. It took a fair bit of convincing the wife to do the above but it would be fair to say with the prices for energy as they are she's now on board. I want a heat pump but it seems to be a minefield of information. I've had two visits from approved installers with one saying yes and one saying don't bother. 🤷
They are digging up the road outside my house to prepare the pipes to deliver hydrogen to my house right now 👀
Viessmann md will be having a stroke. He loved them vitovalors
8 plumbers heat pump technicians come to your house for a day good luck with that....😅
@HeatGeek - you've said you're going to install an electric battery to store your excess energy from the solar panels - could you actually use your shiny new boiler as a "heat battery" by overheating the water using that excess electricity?
Looking good mate a big hug from us all. Liked the fact we could see all the kids and Jo in the video. Men they are growing quickly ❤❤
Yo!!! Far too quick very sad 😔.. hope you and the family are well!!?
@@HeatGeekWe are all doing well on this end 🤙Would be nice we could meet up in the UK sometime soon.
Use a heat geek elite … or 6 😂
I do believe you on this subject but proof in heating your normal house
In cost from aug to march comparison is needed for all elec and gas before and after you have a couple months to tweak your system
Not sure if you intend to have your viesman running in parallel or not
This is fine by me but lets have results done in the right way
You need to monitor all systems and show us none heating engineers approved
Question hot water tank cold inlet cold direct in bottom
Or in bottom with cold mixing in middle with tube up to middle of tank
On a normal tank feed eco cylinder indirect not fancy gledhill
Waiting for your results as i have a viesmann boiler
We have addressed all these questions in other videos. Both this system and outboffoce one are measure for you to access. Link in description
Awesome BBQ Adam! 👍
if i said to the wife ‘i can reduce the flow temperature’ she would be beating me with that radiator and also be reducing our nocturnal interactions to a very low rate 😂
Hahaha importantly, she also knew that didn't mean a colder room.. she ran my heating business for 10 years!
How come a Valiant heat pump and not a Viessmann ?
One of the things that concerns me, is the degree to which the hydrogen option is still being taken seriously. Last week I had some radiators swapped out (new, attractive, oversized ones put in) by a really nice, young engineer (28yrs old). He worked hard, fast and did a super tidy job. I opened the discussion by asking if he was trained or going to train in heat pumps, and he said “there’s a lot of focus in the industry on hydrogen so going to see where things go over the next 5 years”. This is the problem. This wasn’t some old engineer who can hardly use a smart phone and doesn’t want to learn new things and have to do heat calculations, this was a guy the same age as my son who is listening to and being influenced by his peers, and in this case probably his own Dad who IS almost retired and in the same industry.
We'll get em!
Stop type casting, I have just retired although still doing one day a week servicing my customer's boilers, I have had smart phone's from the days when it was a brick fixed in my van, I fitted Condensing boilers 3 years before you had to, and I've been fitting weather comp systems on nearly every Glow worm, Vaillant install for the last 14 years.
What your not understanding is this problem is the 'sheep mentality' of the industry where all must fit a Bosch Wor----- thing or you're useless and do it in a day and don't bother commissioning it, and leave the old controls in use. That's a lot of gas engineers who just WTF attitude, and nothing to do with age.
@@derekclark7545 and I bet you wouldn't have fitted that master bedroom rad, hacked the skirting out, jammed it under the windowsill, stood back and said that looks good!!! What a f***ing bodge.
This is very interesting! When hydrogen first becomes the mainstream fuel source, for automotive applications (because EV can’t scale up for heavy equipment in our lifetime)… the infrastructure for hydrogen will become abundant!!
From there hydrogen can be effectively and efficiently distributed across existing gas networks!🤷♂️
Curious question, those “H2 ready” stickers you see on units… are they on Japanese made products??
The transition between technologies always stirs arguments. Well designed systems will be efficient but you have to get the confidence of the end user first. The misnomer is wor….b… they aren’t even on the playing field when it comes to controlling their own kit.
What the name of the lift to get the HP up there?
Hoorah at last a big announcement on the pointless arguments for Hydrogen.
You should watch our h2 con video
Brand of radiators?
Milan tamara
Hi, super channel! I'm comparing your performance and that of Jones online on Heatpumpmonitor. I notice that yours cycles quite a lot whereas the other one doesn't. Could this one be a bit too powerful and forcing it to stop because it's at its minimum?
There’s lots in that specific example. Too much for here
did you not require volumiser or a buffer at all to increase the system volume?
90% of installations don't need them, and they are installed for no good reason most of the time.
Roger Bisby would be turning in his grave if he saw you slating hydrogen.
Has Roger died?
@@zlmdragon. but he only posted up a video two days ago. What happened?
@@zlmdragon. you’ve gotta be on the wind up 😃
Amazing videos gents! 🔥
Great video is the system all open circuit with sensocomfort controls also is there a volumiser or do the radiators have enough volume
Nearly all systems have enough volume out the box. Especially of open loop. So these obviously do too
👍
@@HeatGeek what about if radiaotors are shut off via trvs?
@@gerardfry4876 then theor scips will be extremely low. Trvs should be set 1c above target wc point and the flow temp control the room temp not the trv
@@HeatGeek thanks, think I understood your point, please correct if I’m mistaken. Trvs should be set higher then design temp allowing sufficient minimum circuit volume for the heat pump negating the need for an additional volumiser whislt also allowing the rads to reach the the designed room temp?
too many chefs comes to mind
Nice job! I counted 8 experts doing the installation. What were the costs of materials and labour?
I am about to replace my entire system and would appreciate one of your experts quoting me for a heat pump. I’m in the Ipswich area.
anything public with hydrogen is a dream, home heating or cars, and thats because of the elephant in the room they never mention, hydrogen embrittlement, whatever you store hydrogen in goes brittle and cracks, not overnight, but over a number of years, imagine a car driving down a road with a dodgy hydrogen tank at 160,000 psi and theres a bump in the road...
this is why you only see prototypes and rental/lease vehicles, so they can claw them back before anything bad happens... but if they sell them and they lose track of a few, and they end up being sold on the 2nd hand market, do you think people will just give them up after 5 10yrs or pay for a new safe tank? hell you cant even get people to replace worn tyres and brakes!
same issue with tanks in the garden and pipes into the house.
when did we have the first hydrogen engine/heating, over 100 years ago, if this problem could be fixed, it would have been by now.
the only thing hydrogen is good for is taking investment cash.....
ASHP is only just about viable in an extremely well insulated house with little or no door/window opening in winter. In any other situation the house will in no way feel warm enough, the heat needs to be on 24/7 as the warmup time is incredibly long (hours) at 45C-55c flow temps. The cost of electricity no matter the so called efficiency will be extremely high and not feasible for the average working people. To be most efficient the flow temps need to be 40C and no more, once you go above that the efficiency literally drops like a stone. Average electricity bill for a semi detached 3 bed home would be about £400 per quarter ON TOP of all other electrical usage. It cannot heat hot water to safe temps regarding legionella etc and requires a BOOST to 65+ degrees, this adds more to the cost of electricity. I did my apprenticeship from 1984-1988 before heat pumps were around and have watched the progression since. I would NOT have a heat pump in my house. Also the total reliance on electricity for EVERYTHING is going to come back and bite people REAL hard at some point. I have written an ASHP calculator that does heat loss calculations for you, allows you to input a flow temp, it will then tell you the rads required, size and output in KW, you can then enter the price per KWh of your electricity supply and give you the running costs per day/week/month/year. With the current price of electricity nearly all installations are unviable from an economic point of view unless you are very wealthy and or have a significant solar installation and don't care and have your big wood burner ready to go, which they all do by the way. I would debate anybody on this subject of the reality versus the hype. from a 40 year heating engineer.
Myth : heat pumps are expensive to run ..
Truth : My electricity bill without solar comes in at around £100 per month during the winter. My heating sits comfortably at 20°c to 23°c all day.
This is from a heat source calculator for a house of my age , For every sq ft of living space, you need about 30 BTU of heating output. That means, for example, that for a 1,000 sq ft home, you would require a 30,000 BTU heat pump (that’s a 2.5-ton heat pump)., so my heat source pump for my house is 60000 but with a weight of 5 tonnes, so how is that going over my roof then
7.00mins. 3 heat meters?.... the street inlet temperature measurement is calculated sum of total energy injection to 3*C water to heat the house? (The true total input efficiency)
Hi Adam. Happy new year and thanks for all the tips. One question I do have is do you have a spec for the rads you used as all the triple column ones I look at appear to be less output than the same size k2. If you have a link that would be great. And thanks again
The Hydrogen add keeps popping up on my Facebook, I just love telling the punters that read the comments just how it's not going to happen, how destructive it is, the percentage of homes that I find with leaks that are within tolerance, the percentage of cowboys doing gas work confirmed by Gas Safe, and how it's going to cost a fortune.
If ever there was a scam about to hit, Hydrogen boilers is it.
Question; Do you have to have a certain loft insulation value, plus cavity wall insulation, to qualify for the air source heat pump grant.
You need loft insulation yes. And your epc cannot suggest you need cavity wall.
Elaborate on this? Why is hydrogen not viable? At college studying gas and our tutor has been talking about the future will be heat pumps or hydrogen.
@@GasTraining You need to burn more of it to get the same heat output, your gas bill will go up, its never going to be cheep, your gas bill will go up, so many can't afford to pay there bill now.
60% of the homes I used to work in doing landlords, service and maintenance have leaks within tolerance, they won't be for hydrogen, so new gas carcass, more money.
Hydrogen. smallest molecule will leak from same place but loads more, its also more flammable, so more cases of TV media event with more home taken down.
40% gas work carried out by cowboys. Fact Gas Safe Register, so more destruction.
Nobody's going to fill that massive infrastructure underground for free so the cost will be passed on at great expense.
The infrastructure underground will need millions spent to fix all the leaks, and to section it up while towns and villages are converted to 100% Hydrogen.
The cost has gone passed what is viable and I not seating here all night with the countless other boring problems it will bring.
Spend the money on upgrading the electrical supply network, build these new fusion nuclear power stations and then we can fit ASHPs by the millions.
Not me though I am mostly retired.
Forgot; The Tenby project has failed , nobody wanted to take up Hydrogen, even with all the free perks, like free boiler install, free gas fire install, free cooker/hob install and £2500,00 grant towards refurbing their homes. After ten months of trying their best the public said, shove it.
Now the idiots want to try their luck in other areas, so desperate is the Hydrogen mob.
Where I live , the government are doing a trial . We may be getting hooked up to hydrogen, around 2000 homes. It's between my area and a place in the North East. Whoever wins gets new boilers installed And run on hydrogen for 2 years
question on the ASHP + water tank. did you install a buffer tank? if not why?
thanks
Will you be doing another video on the cylinder? I am curious about how you have piped the cylinder?
Are the 2 coils coming off another 28mm or are you reducing off a larger curcuit?
Love the hot water cylinder, sorry to everyone else. Are plans available? What is the coil area of your double coil, is it around 3m^2?
Brilliant video mate
Lot of cyclists here
I... have never even heard of freakin' hydrogen boilers!!! What madness is this???
I know this isn't the main focus of you channel but since it's mentioned in this video; could you make an episode about photovoltaics and especially home batteries since there's already enough info on standalone PV but not as much about the sensibility of a home battery.
Can a battery keep up with the demands of a massive consumer such as a heat pump? How much current does a heat pump draw initially and during steady operation?
My heat pump claims to be capable of a "soft start" (addon feature) - would this make sense in conjunction with a home battery? 🔋
Many thanks for the videos!
Are big cast iron rads better for a heat pump? They are very pretty and cost a lot so I’d rather not have to change them.
As long as they are correctly sized for a low enough flow temperature they are absolutely fine (Three of the radiators we fitted in this video are cast iron).
The material doesn’t matter, just the radiator output.
How does the rad volume and material (heat up time) effect system performance? Is greater volume and steel rads better or worse for efficiency? Thanks!
@@petersmith2650 Heat pump manufacturers will specify a minimum system volume for the system being connected to. Radiators with high volumes will help to achieve or exceed this. A larger volume also allows the units to defrost with less impact on the system water temperature.
With the control strategies that we use on heat pumps (Wether compensation, with little indoor temperature variance), the heat up time isn’t really important. Flow temperature changes will be small. On a system that is used with big indoor temperature changes, optimising controls will negate the effect of the high mass of the radiators by turning the heat source on and off based on it learned heat up and cool down times.
So sorry to hear about Hydrogen. Never mind, people tried. We have alternatives.
They are digging up the road outside my house to prepare the pipes to deliver hydrogen to my house right now 👀
That’s the easy bit. The hard bit is finding hydrogen that you’d be able to afford. It’s around 5 x more expensive than bat gas
@@HeatGeek we have an agreement set up to have our costs matched somehow to be equivalent to gas whilst the trial is running.
Almost certain it’s not going to be the future but they are paying me to trial it, nothing to lose on my end other than a slight faff of switching
Great video! Thanks for sharing! QUESTION: It seems like Vaillant is selling out of their aerotherm models is there any news of a new model being released soon?
Also could you share a few more details about the cylinder… I live in Denmark and am planning on installing a Vaillant aerotherm 7kw and an very curious about the design of the cylinder and double coil
So glad to hear Hydrogen Boilers are dead - I explained this to a number of boiler engineers 6 months ago - they all have fallen down the rabbit hole of mains hydrogen - the only version of hydrogen which is valid is Green Hydrogen and this will be limited to certain uses where electric generated from renewables can not be used.
If the hydrogen idea is dead why are they pushing to test hydrogen in Ellesmere port?
Would you recommend moving into this kind of work going forward rather than gas engineering
Have you sold the hydrogen boiler, if not how much space does it take up?
Class, well done all involved 👏👏
I enjoyed that one! I've got the car, panels and battery, Vaillant arotherm plus being installed next month - on a large Victorian detached in Scotland too, who would believe it!
COP?
Very good job wish I had this a few weeks ago could have saved me a drive😂
What kind of radiator is that 600mm one? It look like cast iron ones we had in soviet days here in Ukraine.
How well would a heating pump work in a single pipe heating system ?
I just wish we could do this within some reasonable upfront cost. The need in our home to replace underfloor and boiler makes it way too expensive
has anyone thought of using evacuated solar thermal tubes with a heat pump, because you can get -30 outlet from the heat pump and even on a pretty cloudy day you can get +20C outlet from evacuated solar thermal, obviously that isn't going to work during the night so you would still want a air heat exchanger, but your efficiency during the day time even on the cloudiest of day would be pretty amazing and with propylene glycol you can go down to -50C before it would freeze, so yeh for the night you would have to heat the propylene glycol so that it stays above -40C, but that shouldn't be a terrible amount of energy given specific heat of propylene glycol and that you would only be heating it by a maximum of 10C which would be roughly equivalent to heating water by 5C.
And during the summer you can use the solar thermal directly to make your hot water, say for example when the secondary tank reaches 50C which with an added 700W emersion heater on that secondary tank on a sunny spring or autumn day the solar thermal on it's own should bring you to 30 - 40C in the secondary tank easily, you would want to have the solar thermal coming near the middle of the tank and going down to the bottom and the emersion heating above the solar thermal so you are making sure the immersion heater isn't heating the water that is going out to the solar thermal though.
You would also want a small tank between the heat pump outlet and the solar thermal inlet to mix the outlet temperature PG with ambient temperature PG because otherwise you run the significant risk of thermal shock to the solar thermal which will shatter the tubes, in actuality toy might want to route everything into and out of the tank to not damage the heat pump either because on a sunny but cold day the outlet temperature of the solar thermal could be 100C or so.
I suppose 2 loops with a heat exchanger on each side inside a tank of PG would be best.
Take a look at NIBE’s PVT system. It’s not exactly what you describe, but it is using solar panels as a heat source.
A passivhaus approach will save you a lot of money. At least the 15k on the hydrogen boiler. and that air pump looks expensive and massive.
A passivhaus is liteally the most expensive option.. younhave to build a house
It only makes sense to have a heat pump if the house has solar panels. Correctly installed heat pumps are 300% + more efficient however given the the cost of electricity being 3 times the price and the fact that the amount of people not trained to fit a heat pump properly is far higher than the amount of people who are trained properly...... Fitting a heat pump is still a risk and far too expensive
What about going with something like ThermaSkirt and save so much space on the radiators?
In addition to my rads? Waaay to much uplift.
Really seven days though! 😏 my problem is new build well 10 years old now, with 10 mm plastic microbore pipe work most runs though are 3- 4 meters. Already got solar and two Powerwalls but not sure which way to go as definitely can’t rip up chipboard flooring, oh and typical of new build it’s a dropping system.
On a house that’s less than 10 years old, there’s a fairly good chance that 10mm to each radiator will be fine. This can be confirmed by the maths at the point of system design.
I have a 5KW aroTHERM running well on a 10mm Speedfit system (2017), and when I finally get round to doing my own (2009), I will have a second!
Mark with the "ASL?" LOL.
10:10 Did you mean 6000 kWh? I.e. 6 Megawatt hours. Over what period? Or did you mean 6kW of electrical power?
6000kwh over a year.
I have a couple of flat aress I could mount one on though inevitably any flat roof does need replacement at some point so thibk thats what would out me off rather than the noise.
The roof is epdm not bitumen so not a problem.
i think 90% of people alr have a heat pump i know so kinda late m8
You know people with a hydrogen boiler?
A the waf ( wife accept factor ) went ok
I thought pressure test was for 2 hours at system pressure + 30% ?
For a new system yes. And for commercial yes. This rad system he's been in for 15 years at 2 bar. Holding well so far. The new primary to the heat pump has held at 2 bar for 6 weeks now.. hopefully will lower to 1.5bar when I find time as I think it's passed.
I've just had a 9.5kw Fujitsu air to air system installed (replacing storage heaters in my bungalow) and I'm really surprised how quiet it is. DHW is supplied through a stiebel eltron dce-x 10/12 instant water heater to get rid of the old immersion heater. We're averaging less than 1kwh of electricity on hot water a day. Looking forward to seeing how the AC handles winter in heating mode.
interesting, had this idea a while back but never went through with it, having 10kw solar has allowed electric heaters but no battery yet so tend to turn them off when daylight/solar ends.
An amusing and entertaining video but totally out of touch with the average Joe public's ability to afford or put up with all this upheaval and above all, cost!
It wasn't an advert.

Where did I imply that it was an advert? I said it was a very costly exercise or installation.
