Very helpful video Nigel, thanks. I've been looking into the Mixergy tank as my next move towards full energy electrification (solar and batteries already done). So to hear your endorsement is very encouraging.
I have had mine for over 1 year now. I watched you're previous video on mixergy and took note of buying the mixergy embedded diverter as it has extra settings. I now run a heat pump and its goid at filling 100% of the tank , unfortunately no top down heating. I do wish i had gone for an additional coil in the top of the tank , that would have given me another opportunity to heat water top down. I am like yourself onnlots of FB pages and chats and its amazing how without this tank everyone doesn't know how much water they have i do lol , ots a very useful feature.
We have a heat pump and a "normal" modern water tank installed at the same time as the Heat pump, this only gets heated overnight to 50 degrees during our cheap Intelligent Go time so our water is perfect for morning showers, this takes about 40 minutes with a short peak at 3kW draw that settles to 1.5kW for the rest, it never gets heated during the day and all our solar is exported, if the water is a bit tepid in the evening, who cares, that is what the dish washer is for!
I use the Mixergy scheduler to charge the water tank up with cheap grid electricity at night. If I schedule it with the Eddi, it takes the power straight from the battery and prevents the battery from charging.
Just to throw a curve ball in here, I have an electric combi-boiler. Plumber and sparky advised against it (only works if you're in a one bedroom flat, etc, etc) Anyway, 18 months in and it works just fine in a typical (UK) three bed semi. I considered the Mixergy route but the cost and hassle put me off. I was, however, prepared to swallow my pride and get one installed if the combi didn't suffice but so far, so good.
This got me thinking that we could reduce down to a 90L tank from the 180L (Mixergy) tank we have now. The biggest problem we have is heat loss, because it’s in a vented loft space. We also have long pipe runs meaning it takes a while to get hot water to the tap. The plan is to change next year and donate our existing tank to a charity, an area Mixergy are also active in.
We’ve had ours nearly 2yrs and I don’t know if have bothered with one in hindsight. We had it put in with our ASHP, all plumbed in with a pair of 2 port valves (divert valve didn’t work out properly 🤷♂️) It apparently gets a better COP using the plate heat exchanger vs a regular tank but has to be heated all in one go. I’ve got ours set to heat on our cheap tariff using the ASHP overnight so a full tank is about 2-3kWh or about 20p. If it gets low because of a big cleaning day, I just boost it to full again; takes about an hour. Getting it comparable with the Ecodan is a bit janky tho. They have an interface box which just operates as a switch, feeds back either a 35c low value to the Mitsubishi system, or 66c high to show the load is fulfilled. Our 1st interface didn’t work apparently, and the 2nd got replaced after about 11months. The installers were sorting a different issue with one of the 2 port valves and noticed the interface was really noisy; a very loud relay. The comms with other systems could be better I think.
We are two years in and the tank is connected to a heat pump. We did consider the solar diverter but decided against as using the battery storage made more sense. We have yet to run thr tank out of hot water with a family of 5 and a 210 litre tank. Sometimes 3 baths in quick succession on an evening. It has definitely saved us money, mind i have been running ours at around 50% and think i can shift to 25% most of the time given it warms up quickly. No issues with the heat pump interface either.
If I remember correctly mine was two or three hundred pounds more than an ordinary tank. So the payback period may not be that long - if you are replacing the whole tank anyway. I installed a 300 litre tank because I live by the sea and I want to make sure that I don't run out of hot water when friends and family come to stay in the summer. As compared to a normal tank there is no real disadvantage to installing a large tank (if there is space) because if it's just me I can set it to heat just 20% of the tank.
Whatever I do in my house, the first question from other people seems to be “when will that pay for itself?”. To me it is like anything, you get it because it is what you want or need at the time. Just because it is a “green” option, why is there this perception that everything needs to pay for itself or have an ROI?
I have an ASHP and have set this to heat during the off peak hours. As you said exporting as much as you can makes far more sense getting 15p per kWh rather than spensing just 7p during off peak.
I was watching a Mixergy RUclips video quoting you speaking about your use of a Mixergy tank. You mentioned that you were running your channel to help people how to implement all these areas and whilst I understand the issues technically I don't understand it practically. For example I am living in a 1970's townhouse needing a replacement of its roof, upgrades to its electrical system to support an Bidirectional supply for an EV either a Ionic 5 or Enyaq 80 via a Hegger KNX Protocol compatible bidirectional consumer unit as its compatible with Home Assistant I just hope I can find someone who knows how to fit & service a mixergy tank near Oxford where I live.
I also have a 2 year old Mixergy tank but I went from a massive 200ltr immersion heater heated hot water tank to a 100ltr Mixergy tank with solar diversion and a heat exchanger. I don’t use the heat exchanger as I have desired not to go down the ASHP route as my bungalow is “all electric”. I have three issues with my Mixergy tank 1) I wish that it could carry out sterilisations when there is excess solar - I normally heat the tank to 51C but even at this time of the year I can get it to almost 80C via my Eddi but it won’t do a sterislation at this temperature whereas fortnightly it will sterilise at 55C by heating the whole tank. Also why does it need stern sati on 2 weekly? When I was working at sea we were required to sterilise water storage and AC systems every 3 months. 2) the insulation doesn’t appear to be a s good on my Mixergy tank as it was on my old tank that would last 2-3 days without needing heating 3) Due to the way that the Mixergy appointed plumbers installed the tank I cannot open the control panel cover to adjust the maximum temperature that the Eddi heats the water to down from scalding hot to a most reasonable (and less wasteful of solar energy I could export!). Unfortunately the plumbers put a copper pipe so close to the control panel that while I can undo the screws I cannot get the cover off! 4) Something to consider before going ahead with replacing a gravity fed tank with a Mixergy mains pressure fed tank is it you have an instant heat or gravity fed mixer shower………… I have to replace my electric pumped shower as it couldn’t take the mains pressure so I had an on cost of replacing the shower too and now I have a huge empty cold water tank in my loft which is a brilliant place to hide valuables when I go away on holiday - a security box disguised as a cold water tank as all the piping to the tank has been removed / disconnected but the tank itself had to stay as it was too big to get down via the loft hatch! Otherwise I’ve been very pleased with my Mixergy tank and have no problem with most days being able to only heat variable volumes of water as I need more or less hot water. I’m single so that’s easier than if there were 3-4 people living in the house but then I would have installed a larger tank. I didn’t pay a penny to heat hot water from mid May through to late September this year too as the solar diversion will start to heat the tank with as little as 200w of solar generated energy - my house has a 200w base load that needs to be overcome before diversion takes place. And even on pretty dull days my 14 year old panels can provide enough energy to at least maintain the tank temperature without using the Mixergy “maintain temperature” function that uses mains electricity. Even at 1030 on this dull Sunday in Central Scotland my panels are generating 300w of energy 200 of them going to the house and 100 to the Eddi/Mixergy tank so it’s at least maintaining the set 51C temperature of the 56% of the tank volume even if it isn’t heating it as well. I have found that with the extra space now available in my airing cupboard from having a much smaller hot water tank if I put newly washed and dried duvet covers, sheets and towels over the top of the Mixergy the added insulation from them helps keep the tank warm for longer too!
Wow that's a bad i stall to not make a access cover accessible . That needs fixing . Drill hole in the right place ti allow screwdriver ?? There was a software update that stopped sterilisation when using my eddi but I had that reversed out. Mixerfy have disabled sterilisation at my request I do it manually on solar excess now. So long as cold section goes above set point it registers as a sterilisation. Id suggest setting tank temp higher than minimum sterilisation. I set 54 and 51 so there's a range to work within .
If your solar thermal had been installed on your gable wall would you have got more hot water during the winter,Now you have data from the gable panels how much hot water would have been generated
have a McDonald 200 slimline tank. This was heated using solar using Eddi until octopus started paying for export @ £0.15 so stopped the Eddi! Now have ashp which heats the water (full tank) at 03:00 AM to 47C (adequate for thermostat showers!) The tankful costs 2kW ASHP electricity @£0.07 2 showers /dishwasher/handwash still have hot water available. The cold is added to bottom of tank and does not seem to mix with hot at top. Legionella is done every 2 weeks and this is controlled by the ASHP switching the immersion heater via the Eddi until the thermal trip on the heater trips. The ASHP still only heats to 47C during this cycle.
Norfolk is renowned for hard water, how does the system deal with this? Any extra gadgets? Also service, is it annual and cost? I'm trying to decide between mixenegy and sunamp....
Super hard water here. No issues with mixergy so far , no extra concerns . Heat pump coil wouldn't be good though with hard water . Sunamp seems more money and more complicated but efficiency wise is good 👍
It is warranted but with all cylinders they want annual services to make rain the warranty. Doesn't impress me as they on the other hand say if you subscribe you don't need services as its monitored online. I don't subscribe
That's a very good point. Visitors have often remarked on how good the shower is. I had never really thought it through but, yes, as you point out it's because it's mains pressure. 👍😀
Yes our whole ashp system is mains pressur. Originally had power shower, but we live in high pressure area so when system was changed found that the Mira power shower is not meant for our pressure - water was escaping from all joints inside power shower. Then along comes Thames water and replumbs the village (pipes were bursting frequently!) and reduces the pressure to less than the power shower produced!!
We got our tank installed October 2022. No regrets, similar experience to the video. We used to send all solar diversion to the tank but we established it was more cost effective to sell energy and just fill to the level we needed. We need aroud 50% to 70% of the tank each day on average. We also switch off all the mixergy control settings so we have full control, especially when it came to the heat cycles for cleansing. We heat by gas when we have no solar, the unit rate is cheaper than electric even when on off peak, its also far quicker to heat too this way. The savings for us have come from the kids volume of use, it gives real perspective of what the family uses for baths/showers. Also you only heat to the amount you need, we cap the kids volume of hot water rather than having a tank at 100%. You appreciate how much water you save not just energy! It's pretty scary how much water our family was using before, so much was wasted.
I’m still arguing with myself in regards to heat pumps for central heating , the grant from the government doesn’t seem to give the grant for those who would prefer ATA , do I want to get rid of my gas boiler = yes , seems the grant is decriminalising for households who choose to get rid of gas boilers but only if one chooses ATW = surly that’s crazy , people say what about the hot water tank , well at the moment I have a tank with an immersion heater yet I think it better to have a mini electric heater under the sink in kitchen and bathroom so when you turn the hot water tap on you’ve got instant hot water , I put my immersion on to wash dishes or to wash each morning in the bathroom then I’ve wasted the water in the tank to get cold again till the next time I put the immersion on , maybe I’m not looking at this correctly yet it makes more sense to having mini electric heaters for the water with no tank needed , the system I think I need wouldn’t even reach the grant set out by the government , wow either I’m crazy quite possibly or the grant system is , is there a minister for logical thinking maybe that’s on the agenda for a cunning plan to have more households to have heat pumps your choice scenario.
I have a 60L 3kwh immersion heater tank and then the water goes into a 1.5kwh 6L water heater before going to the taps. I can bypass the 6L water heater.
@@teaernuk I wanted to get rid of the tank altogether because it fed from a tank in the loft so always thinking about frost in the winter affecting the loft plus it makes sense to me to use what little water I do use with mini underneath water heaters rather than waiting for the immersion to heat the water before use , there’s so little information in regards to the mini water heaters = good or bad efficient or not , for me at least I know I would use much less electricity rather than the system I have , strange the government want us to be more green but they won’t allow me to go green which suits my house but ironically would actually be more green because I would be using less electricity, just like the ATA I would use less electricity because I wouldn’t be trying to heat areas that I don’t use 70% of the time , the grant should be for the house owner as long as they can prove that they have got ridden of the gas boiler and even show the receipts of the ATA units along with the installation costs , I struggle to understand why that is not logical = maybe it’s too logical that they can’t get their heads around.
@@teaernuk What about the hot water in the bathroom? Is that also fed from that unit ? Why didn’t you go for the mini water heaters which are tiny in comparison,

That doesn't sound right, my Eddi works perfectly, just be the battery not responding correctly in the charging period

How big a power draw?

There isn't really an alternative to Mixergy, it's quite unique. Really clever.

I am disabled & on benefits would Mixenegy work with me to help me buy a second hand unit via them?
@ Contact them, they may be able to help.

Hi, you missed a great advantage, it's mains fed hot water, thus effectively giving you a very powerful shower and will fill a bath very quickly.
I was about to ask this, so just to confirm, it's mains pressure water coming out of tank, with no additional pump/gadgets required?
I Just take it for granted ,but yes it's pressurised , we don't have power shower pumps here
