RE: Re: [OT]Ground Source Heat Pump running costs

Well heat pumps and rads are not really suited, the efficiency of the
heat
pump will be seriously reduced when needing to run at the high temperatures
required by the rads in cold weather. My heat pump manages to maintain its
internal hot water tank at 50 degrees for my hot water no problem but is at
its most efficient when running my UFH with a flow temperature between 30
and 40 degrees.

We've looked at GSHP on two occasions now, and despite being enthusiastic
we've
always stopped short of getting quotes etc. This discussion is worrying as
I
was about to start looking at this again. Our house (converted barn) has
just
had alot of insulation added to roof as part of adding an extension, plus
the
extension is designed to act as a solar collector, but we have radiators
and
it
would be a real pain to convert to UFH. One of the main stoppers has been
water
temperature, and we've never got to bottom of that. My wife likes really
hot
baths and is convinced a GSHP won't 'cut the cloth'. Anyone be prepared to
comment on this perception (and maybe answer few other questions, maybe
off-list, if not of general interest?)
