I've just heard that Phoenix Natural Gas in Northern Ireland is
raising prices again, this time by 17%. The price was raised 30% in
Septmber, so that costs will have gone up by more than 50% in four
months. The General Consumer Council said it was "appalling" and a
"severe blow". (BBC)

Surely oil must now be cheaper? But what about electricity? E.g. using
a thermostatically controlled fan heater. Gas seems now to be an
extortionate luxury, and with oil one does at least have the
competition between local suppliers.

I would be interested in some figures on this sort of thing as I am
trying
to work out whether it is cheaper to heat my water overnight using oil or
economy 7.

For heating water overnight E7 is surely most economical, but what if
someone wants a bath in the evening? Is the water going to be hot
enough by then?

We heat the water twice a day and the E7 runs up to 8am so I was thinking of
using E7 for the mornings hot water and then oil for the second hot water
run of the day in the evening.

The thing i was pondering though is since I have the boiler on anyway to
heat the house in the morning - would it use that much more oil if it had to
heat the water as well?

What would be useful is some idea of the amount of each type of fuel used to
heat say 100 litres of water, though I guess this would vary enormously from
appliance to appliance.
