Heat pumps are showing the lack of skills in the domestic market. You can’t over power a bad system design and commission like you could with a gas boiler. You need to know your systems and how to design one. The industry is massively lacking these skills. It’s rare to see such an installer like your self who does know how to design a system and also be upfront if a customer on its shortfalls when it’s a phased project

It's great to see some quality fact based videos going up around heatpumps. I love the content that you produce, and the fact it's all explained and designed not just thrown in, and then the detail is shared is great. You are doing some great work with unpicking the rubbish going around about heatpumps that is in the media at the moment. I'm an electrical engineer by profession, so not really into heating/mechanical systems in a big way but I can apprecaite the time that is spent doing the calcs to make sure the system is correctly designed.

I think what you said at the end is key: you still need to do the calculations.

Great to see a less-than-ideal situation; ideal situations are easy, we need to deal with the non-ideal homes!

I appreciate these videos. It’s really helpful to make a judgement from the experience of somebody who has lived with the system. Thanks for putting the work in!

Another quality installation and satisfied client. Well done!

Great to hear the feedback from your customer. He'll definitely see an improvement with the underfloor heating!

Another great Heat Geek install. Thanks for sharing.

I have solar panels that I don't get any fit payments back from, I had an IBoost installed & that usually means I don't need the boiler to generate bathing/washing water even in the winter as long it's not cloudy. I did get a new gas boiler fitted to replace a 20yr old GlowWorm non condensing for a Vaillant ecofit pure. I'm now thinking with all our double radiators that are maybe 3yrs old now would be suited better to a heatpump in the rear garden would be much more efficient & effective at keeping the house warm all day rather than the 3 to 4hrs per day with the gas boiler. Great videos keep them coming. Shame you aren't in Yorkshire Urban Plumber. thanks.

We got one of these units as well since february (different country, 7kW model and floor heating + convector combi) and so far the unit has been amazing. We are obviously getting abit higher efficiency but I'm amazed by how well this seems to work on those single panel radiators. We had them too but replaced them.

Very encouraging story.😀👍 Just for reference what was the actual flow temp at -2C?

Fantastic informative content. As per previous, videos showing installation in less than ideal conditions are useful. We are in a 3 bed detached built in 2000, insulation levels are very good but we are stuck with 10mm microbore to radiators feeding off 22mm flow and return. Is there any way you can make heat pumps work with micro bore or would any installation need to see microbore ripped out?

Great video. So positive

The magical Arotherm Plus strikes again! Nicely done. I'm guessing no buffer tank?

This system will be so much better when the home owner Patrick installs his UFH system. We love our Valliant Aerotherm 7kW heat pump. Our COP is 3.5 at the min. With existing radiators from the old combi gas boiler heating system.

Great channel, and great content mate. So useful, I'm in a detached 70's house and with an old boiler, I do not want to replace it with a new one. I've already got solar, battery, share of a ripple energy wind farm (check it out, v cool lower cost and green energy), and a brand new unvented cylinder Eventually we will remodel the downstairs, with underfloor and upstairs will stay the same, so this gives me the kind of steer I've been looking for! If only you guys covered hampshire!

4 bed detached 128m². Installed 7kW Daikin Altherma in June. 11 rads replaced plus new cylinder. Cost £6k. COP to date 3.6 heating and 2.3 DHW. Ave use in Dec 20kWh Heat and 4 kWh DHW. Designed for 50⁰flow@-2⁰ext but in Dec had to turn the system down as too hot. Now use 50⁰@-15⁰ext/28⁰@18⁰ext which maintains 20-21⁰ downstairs and 19⁰ upstairs. 🤓

just wondering. we are looking between a SPRsun heatpump or Vailliant heatpump and using a buffertank with a warm water coil in there or 2 tanks, one for warm water and one for buffer. we did several price requests but its going from only need of a warmwater tank to needing a minimal 500 liter buffertank with warmwater coil otherwise we would get issue's with the heatpump. (i'n in the Netherlands and lost a bit where to make my choice. (we have floorheating on 1st and second floor and low temperature radiators on the 3th floor (our current boiler is set to 40 degrees)

I am not surprised at all as everyone told me I was mad installing an ashp in my property as it is a 200 year old solid stone property 200 square metres. But I was confident it would work so I had one installed and hey presto it's far cheaper than the oil boiler and more comfortable we have the house at a constant 20 degrees or there abouts and the heat pump has a meter on it and it has used 2000 kwh so far this year. I have a friend who has a 70s house and his gas bill was 1300 quid for 3 months of winter. I get around a cop of 4. I have no idea if 2000 kwh is good but it's cheaper than the oil

Good job, nice to see your expectations were exceeded by a good margin! What's the design flow temperature, peak demand and heat curve of the setup?
