Electricity bill?

[Aragorn84]

heaters account for half your consumption[48 kw]
are you sure they are 2k and not 2 heat settings and up to 3kw that would make more sense approaching 75kwh
towel rail will be another 9kw as its unlikely to cut out much immersion another 6kw so that is around 90kw so 15 to find

what lighting do you have down lighters can easily add up to another kwh

His consumption figures are for two days though...

Hes using 52units a day, and as you say, 48 of those are heating.

2 days so it is that makes more sense
a horendous amount but easily accounted for then
