Default heating water

I've just installed a 65lt hot water tank, it has 2 heating coils and
an immersion. I haven't got around to connecting the 2 heating coils
so for now it runs on just a 1 kw immersion heater... I connected up
my 1.2kw generator ( just a cheapy from B&Q, not a marine genset) and
it took 2 hours to get warm and about 3 hours to hot.... For no very
good reason I had thought it would heat in about an hour. I have tried
looking up calorific values of water etc, but just got myself
confused... anybody here shed some light for me..

thanks
Nigel




My countertop distiller has a 4 litre boiler with a 1500 watt heater in
its base. It takes it about 35 minutes to start it boiling so you can
hear it and about 5 hours to boil it dry....only 4 litres. 1KW isn't
much power to heat water. Look on your home water heater. Mine's 240VAC
and 8KW and takes over an hour to recover from my honey's "warmup
shower"...(c;

She thinks hot water tanks are like NiCd batteries....you gotta drain
them until they are dead to prevent them from failing!
