Re: Electric vs gas water heating in the summer?

The term boiler is historical. The new CORGI exams specify that the term "water heater" be used. If you answer boiler you fail the Qn. The term water heater mixes up an actual heater that heats water for DHW use, so it doesn't improve matters. No one will use the term water heater until makers stop using the word "boiler". Boilers sounds Fred Dibnahish.

A term like "heat generator" would be more specific and not confuse.

My gut feel is that this is true. My house (built in 1987) seems very well insulated and doesn't require a lot of heating.

I didn't bother. I just got a new tank without the hole. What do I want with an immersion heater!

Like whether the walls will be able to hold up the insulation!

I could have a bath right now with just water from the "cold" tank in the roof space. As we have had such hot weather for a week, the water is tepid, perfectly comfortable enough for a bath.

Well, ok, but the place still seems not to need a huge amount of heating. Maybe it's the three jumpers and thermals that I wear? :-)

And how does the annual cost for DCH on gas compare to heating water on peak time electricity ?

If you build a straw bale house the bales are held in place by stakes and the cement isn't even required for that, just to protect from the elements (and mice).

Whoops - decimal point in wrong place - 980W per deg C. Walls are gritstone which is useless as an insulator but large quantities of Kingspan are getting there.
