I have a question for you.
New build (2019) which is super efficient. We've installed AC cassettes in 7 rooms (basically all except bathrooms / hallways). We have two of these powering them.
Is it worth replacing our gas boiler with a heatpump or could / should we just run individual units to heat rooms either on a schedule or on demand with the AC and turn off the rads in those rooms?
We've got wet underfloor heating on the ground floor if that makes any difference.
Soul-
I can't see the system performance graphs for the AC units but I'll have a proper look over lunch. It would really boil down to their efficiency at heating...
My immediate gut reaction would be that if you've got UFH in already then yes it would be worthwhile to swap to a HP for that and the DHW, it'll be a more pleasant heat than using the AC all the time which would make the place quite dry.

Oh hey all,
Yes indeed heat pumps are sort of my thing. I've worked in the industry for sixteen years now and I've run the gamut from domestic installations all the way up to commercial and industrial projects which is what I'm at these days.
I'm a little out of touch on the current grants and requirements for UK domestic market and we've pivoted to modular plant room construction so don't do a lot of domestic these days (did recently complete a plantroom for the home of a senior partner at Foster & Partners, pictured below) but I'm happy to advise to the best of my knowledge and I know some good contacts in UK for suppliers and installers who would be able to help.
I'll get through the recent questions above this morning and if anyone has any other questions just fire ahead.
