My friend is too scared to turn on the immersion heater during the

Not from an immersion heater she wont.

Total heat loss from a decent cylinder is probably less than 50W


Water kept at 60C in a 20C room for 2 days? Things have moved on since
my day - do you have a link to a cylinder that can manage that?

Ah and again - my inability to understand heat loss - 50W standing loss
is not untypical for a decent tank. Fore example:

I have seen so many peopel that worry needlessly about their hot water.
from people who think that a half filled kettle or having a shower
insyead of a bath will save the planet, to people who think that solar
water heaters on theior rooves will save half their heating costs - when
its half their water heating costs.

I use the same ampunt of hot water summer and winter, In summer I use
virtually no oil at all. In winter I use over 250l a WEEK

I am glad I am not the only one with an incurably poorly insulated
house!

My house is VERY well insulated. Its just BIG
