Good. Then perhaps Ken you answer a query. I have a modern immersion
heater ( the green type with a jacket integral) where I am and need to
know whether it is cheaper to turn it on for an hour when required or
leave it on all the time. I am out most of the day, most days and so
do not draw much water. Actually, I use it even less now as the stove
has a very efficient back boiler which heats the water up quickly.
My youngest in Windsor asked me the same question the other day.
