visited a relative who just had one of these and was totally unimpressed.
definitely not a cosy house, radiators barely warm and water not very hot.
i'll take our gas boiler any day.
came home to a decent piping hot shower and warm radiators.
for the record they also use a lot of electric, noisy, take up space and don't work with microbore pipes.

Woeful substitute for what we have already, it won’t be the alternative for the future that’s for sure…..unless the government want us all to freeze to death…..Quote:

The golden rule is: always insulate and draughtproof your property as much as possible before considering any changes to the C/H system. In that way you will considerably reduce the amount of fuel you currently use and maybe get your property's heat load low enough that an ASHP could do the job. Unfortunately most people assume that you can simply replace an existing gas or oil boiler with an ASHP without following the golden rule.
I agree with the OP though that ASHP is best suited to UFH or if not feasible, install larger radiators and replace microbore pipework with 15mm/22mm. DHW will likely always be an issue though. Pretty sure that heat pump technology will improve and we'll get much better COP values in the future - hence another reason not to rush into installing ASHPs right now!
As they will have had their clotshots they will be zombified and simply live off the pickings of the contents of each other's' crania whilst waiting for the poles to invert.Quote:

To be fair, the house it's in is designed for it (18-inch-thick insulated walls, a heat recovery system, a small PV system, triple glazing and underfloor heating everywhere).
What I found at first was I couldn't get to grips with it and that it was totally frustrating. It took me a while to realize it won't work if you want instantaneous "on-demand" control. You have to leave it on almost all the time and draw from the slowly collected heat as you use the hot water and heating during your use of your house over a 24-hour cycle. Essentially, it's a system for people who are willing to plan.
It's actually very quiet. The house is cozily warm all the year and it's very cheap to run - my total electricity bill is less than 450GBP a year (I don't have gas).
Wow, you have a fantastic set up there. MVHR + massive wall insulation + PV + TG + UFH...... ideal! Out of interest do you how many kWh you use p.a. per sq metre of house? There are very few houses in the U.K. that come anywhere near that kind of construction, hence ASHP not really viable for the majority.Quote:

For 2023, it used 1,316 kWh and has a footprint of 105m2. I think that qualifies.Quote:

From your figures I make it 12.5 kWh/sq.m., so yes, less than 15.0 = passivhaus! The electricity price is quite expensive there then: £450 for 1316 kWh is approx 35p per kWh but still £450 p.a. is still hugely different to the bill for an average house in the UK.Quote:

I will avoid both as long as I can until they improve or they change to something better.
It's still worth improving the insulation in older houses as much as you can, if only to reduce the heating bills (the payback time can be quite short) - but I agree it is highly unlikely that you could achieve PassivHaus accreditation in anything other than a new purpose-built ecohome.Quote:
