Re: Modern Home Servers - Power Savings

But most of the time, that heat is in the wrong place.  It doesn't do
me
much good for the wall behind my fridge to be all toasty, for example.
The heat from a condensing dryer will be warming a kitchen or utiltiy
room, which probably isn't all that useful.

Also consider that a condensing gas boiler is a far more efficient
source of heat than electricity from a power station.  Cutting energy
used by electrical appliances and replacing any lost heat with that from
the boiler is a win.

I agree about the heat recovery, though.  I keep meaning to fit fans in
our downstairs rooms (10ft ceilings) - the temperature of the air near
the ceiling in winter is unbelievable, and I could probably drop the
thermostat a few degrees if I ever got off my arse and fitted them!
