$107 here, last month 97 the month before with power shop
was paying upto 150 with mercury and 100 in the summer
3 tanks, one 3 foot, 2 x 90 litre all heated .
So not too bad..
Anyone wanna join power shop drop me a line then I get 25 bucks and you get 50 off ya bill hehe.
So i really dont think tanks use that much
Mind you my house is well insulated and use gas heater and open fire to keep it warmish
saying that its not really really cold yet is it
