I fully understand that electricity is definitely not green for heating. I seem to remember that calorie for calorie, if you heat water directly with a fuel and compare that to electricity created by a fuel (as in gas fired power station) then you get about 30% of the heat you would have done if you'd used the gas directly.
However, we've not got main gas. Calor gas is a lot more expensive than mains gas (and I don't want the gas cylinder around either).
This is an indoor bathroom, so fire at the tub - nope.
We have a multi-fuel stove that doesn't heat water. We had a previous bad experience with a rayburn with a back boiler so didn't want to go that way on the hot water. We had too much hot water, even with the fire shut down and ashed over, on a windy night the system would boil and usually about 2am we had to get up to deal with it, having been woken by the thunder of pipes and the fun sound of steam jetting into the header tank.
So our long term plan, is DIY solar hot water. Our short term is having an occasional bath as a treat for sore muscles, with an electric heating system, at least as a top up. Will make a start with heating kettles on the top of the multi-fuel (in winter) and then use the electric shower and then having *something* to finish off, and to keep it warm while soaking. Hence the dishwasher pump idea. Do take on board that it is only for small quantities of water, so maybe not quite so clever after all.
If someone can suggest a heater and circulator that is small, that would be really helpful. Small as in fit under a bath. So can fill the bath with warm water (that may or may not be hot enough) and then top up the heating with a little circulating heater. |
