We have a 2 bed detached house which only has electric. We have 5 storage heaters and are on an economy 7 tariff. Last year we used all of the heaters and just dealt with the expensive bills (roughly £150 a month) but this year we have bought a Calor gas fire so have decided to only have 2 of the storage heaters on and use the fire to heat the rest of the house. After recently getting a bill from our electricity supplier, it turns out that only having 2 of the heaters on is just as expensive as running all 5. Can anyone help with this? This doesn't seem right to us as otherwise what is the point in having 3 of them turned off? The 3 that are off are all turned off at the wall and of the 2 that we have on, 1 of them is on maximum input with minimum output and the other is only medium input and minimum output.
During the summer we were only using £30 a month on electric so we know that the increase is down to us turning the storage heaters on. The most frustrating thing is that they cost us £120 a month to run but don't actually heat the house up at all. By the time that myself and my partner get home from work all of the heat has escaped from the heaters and the house is freezing. We recently bought a thermometer to see exactly how cold the house is and in the spare bedroom (the heater is on max input and the door to this room is kept closed) it never got above 15 degrees regardless of the time of day; surely the heaters should be providing more heat than this?
Any help or advice with this would be greatly appreciated!
