True, but heat is energy - and heat moves.  Many people confuse temperature
with heat, they are two different things.

Looking at replacing our boiler with a condensing gas boiler at the moment,
but our current boiler is a small commercial boiler - a new equivalent is
very expensive.  You can buy a lot of gas for £6,000.
I've been seriously looking at a wind turbine powering a heat store.
Planning is an issue at the moment - even though there is a commmercial
windfarm with 23 x 350kW turbines nearby and just last week the local
school
stuck one up.

One thing I do is leave the bath water to cool down before emptying!!!
There's a lot of heat there, which would otherwise go down the drain. 
Yeah,
I'm *that* tight!
