I used to heat hot water with wood and coal.. But, went to Solar hot water
and liked the fact there wasn't any clean up to perform.
I think that system lasted 15-17 years before dying.
My multi-fuel boiler is just burning oil these days..
Heating both my domestic hot water and providing heat..
I'm waiting for a new heatpump unit to arrive. Hoping it's here before April..
And the end of the
real heating season.
This one had a leak..
