Jan RosenowNew @[email protected] heat pump report is out!
“the pace of installation is growing rapidly with sales at record levels”
@Can you recommend a practical guide for a home owner thinking of installation. Her gas boiler is coming towards the end of its life. I forwarded the information you gave about why buying another “convertible to hydrogen” unlikely to be wise.
Her first attempt at getting quotes for air pumps have left some doubts. Octopus energy pumps not big enough for house. Too much glass in living room. Different advice re radiators. (Downstairs she has underfloor pipe heating).
Huge difference in price between the two quotes and the higher one from a company I have reason to mistrust.
It is hard to know who to turn to!
will_shake@Fascinatorfun @janrosenow do you know about 'Heat Geek', they are training heat pump installers, provide consumer information and have a list of trained installers. Look on YouTube.
@Fascinatorfun @janrosenow System design appears to be the most critical factor in getting a pump to work efficiently. The time involved to make e good job can raise cost.
Ian Bowns@Fascinatorfun I've found a number of Youtube channels v useful, esp Heat Geek & EV Man's. Really no alternative at the moment to learning quite a bit about it, as there are installers out there who really don't know what thery're talking about. We sought three quotes, companies rec'd by Vaillant. Only got 1 back, though they all visited & promised. 1 suggested over-specified system, to ensure it would work, but throwing all the benefits out of the window. Too expensive for us, even with grant.
Stephen CrownI would look at Heat Geek installer map in the first instance for competent people as that’s the most important thing to get right at this early phase of the #HeatPump transition in the UK

Also, whether it is #AirToAir (known as Air Conditioning) or #AirToWater based #HeatPump #ASHP, one of the most important things is *not* to be oversized in kW output.
The results of both approaches in two houses are in some of my posts here on Mastodon
I thinks it helps if people understand this is a transition and not always a drop in replacement for a gas boiler if going the #AirToWater route
Most houses will need a little all the way to a lot of *system* changes (eg pipework upgrades, radiator replacements, space for a hot water cylinder)
Insulation is important, but is just part of the maths calc. of what size heat pump, radiator size and pipework size to install/upgrade to, so not to worry too much
And also, tell people 2 look around in towns/cities etc. as most businesses are heated (&cooled) by the #AirToAir #A2A air conditioning variety of #HeatPump & these are often in poorly insulated buildings
Business &commercial sector in U.K. seem much further ahead with this transition, as they appreciate the #A2A variety *also* does cooling in the summer which the #AirToWater #A2W variety can’t when paired with radiators
They just work if designed/installed well
