Agree that correct radiators is important for a successful outcome. We upgraded all our radiators and now achieve 21C all the time at a flow temp of only 35C. Aira designed and installed our ASHP system. Also important is insulation. We upgraded all our windows and doors beforehand.
Very nice. Sounds like a good system. We upgraded our loft insulation (which is a no-brainer for all homeowners) and I also went round and replaced any failing/drafty double-glazing window seals.
Re towel rails generally they're not for heating the bathroom but often with a high temp flow a small towel rail will overcome the towels hindering the heating of the room and maintain a good temperature in the bathroom. When swapping to a heat pump if towels are left on it all the time you will find the bathroom tends to be colder leading to condensation issues. Often it's a better idea to increase the size of the towel rail if it's going to have towels left on it when swapping to a heat pump.
Thanks for uploading and will be good to see a heat geek install rather than another octopus. You will be right about decommissioning solar divert, no longer needed. How many litres does your mixergy hold?
Thanks for your comments. We're thinking that we'll disable to solar divert, let the inverter charge the batteries and afterwards dump the remainder into the grid, then, when the heat pump needs to heat the water we'll use the batteries and/or the electricity we 'stored' in the grid. We're on Octopus Agile so we export for 15p/kWh and (on average) buy for less than that. I like the concept of using the grid as a giant battery. Our Mixergy is a little small for the house, as it's only 150L and we have a five bedroom home, but there are only three of us so it conformed to the '50L per person per day' guideline. I'm hoping that a 7kW heat pump will make light work of heating 150L of water!
We upgraded our loft installation to the recommended 30cm, but that was before we were even considering a heat pump, because it's easy to do and saves you money no matter what kind of heating system you have. Our EPC is now 99A! Oh, I also went around all the windows and replaced any rubber seals that had failed and were letting drafts in. This is another easy job and well worth doing.
@@Chatterisdotbiz thank you. I don't know how the towel rails will perform but I asked on the Facebook forums and apparently they're fine. I guess we'll find out very soon. 😬 Yeah, that nixie clock is pretty cool. 🙂
@ you could always have a colder shower so the room feels warm when you get out of it 😊. Looking forward to…..hate the expression, but no other words cover it…..journey lol
How much did you shop around before going with heat geek. I’ve spent 6 months with them trying to make a system cost effective, and failed (over £22K before BUS grant), then went to Octopus and for exactly the same install (pretty much) they are coming in over £11K cheaper. This doesn’t seem to be an isolated case either, I’ve spoken to two other prominent you tubers that went with octopus and they had the same experience. My install ended up being a 9kw ASHP, new 250l cylinder, 13 new radiators and because we have micro bore pipework there will be a volumiser (nothing wrong with that) just to get the volume of water in the loop up. After BUS it’s only £3.6K which I thought was pretty darned excellent, certainly compared to the £15K Heat Geek we’re quoting anyway.
Funnily enough I was just called by Octopus, keen to meet their end of month sales targets. I pushed them on their pricing for an explanation and he was quite open with me that they are basically installing at cost right now as they want to establish themselves as the Tesla of Heat Pump installers. That explains a lot. But as he wanted a signature right away (I was going to do it Monday anyway) I pushed them a litte, got free service plans for 2 years and an installation of another radiator (they had asked for me to use a space heater in a snug with limited access...but after thinking about it I want them to solve the problem not add another heat source.). So all in all, happy with the result, and worth knowing for anyone else looking at heat pumps right now.
As other have said here, Octopus are VERY competitive at the moment and that sounds like they are doing it at zero margin in-order to gain market share. I did speak to Octopus and other local guys, but I opted for our local Heat Geek. It was more expensive than Octopus but I like Heat Geek's philosophy and their efficiency guarentee, so that made me spend the extra. (Oh, and Octopus couldn't offer quite what we wanted.)
I did get a quote from Octopus but they couldn't cope with my desire to keep our Mixergy cylinder and so couldn't do the job. The Vaillant was recommended by Heat Geek and they seem like a decent, leading manufacturer. Are you on a heat pump journey?
@@timminsit It's surprising that Octopus wouldn't use the Mixergy tank, maybe they just have set parameters and worry that you might have complained afterwards if it wasn't large enough. Having said that, you are likely to get a better heat pump install with a Heat Geek installer, albeit at a higher cost.
@@MentalLentil-ev9jryeah, I think that the size of the tank was their primary concern. They have very rigid rules about such things. I'm happy with my Heat Geek experience so far and I like their performance guarantee.
If you find the video boring, watch something else. No need to leave a discouraging comment. I found the video unique and interesting. More please and thank you.

Thanks, this video was very informative, delivered in non tech terms and helpful to anyone researching this. No need for you to apologize to anyone.
Thank you Gerry, that's very kind.

Thanks for the advice. For now, we'll see how we get on and swap them if necessary.
I was actually expecting a Harry Enfield spoof..
Dude!

What extra if any insulation did you fit

Enjoyed your vblog, will the towel rails in the bathrooms meet the heat loss calc? As an aside I love your nixie clock.

I believe octopus are swallowing costs to get ahead in the market

What capacity is your Hot water tank?
Ta
The tank is 150L. A little small for a five bedroom house, but it works well for the three of us. We've never run out of hot water.
Hi Jason. Did you get a quote from octopus for the installation? Why a vaillaint heat pump although i here lots of others choosing this manufacturer?
I did get a quote from Octopus but they couldn't cope with my desire to keep our Mixergy cylinder and so couldn't do the job. The Vaillant was recommended by Heat Geek and they seem like a decent, leading manufacturer. Are you on a heat pump journey?
Not on the journey yet but learning more and more about it. Keep up the videos as they are very informative!!!
@@timminsit Strange, I am getting an HP fitted with Octopus and keeping my Mixergy cylinder.
