Hey. Our house is solely electric (we have these heaters I will attach a photo) insulation is awful so even if the room is red hot. You turn it off and within minutes it's stone cold again. It isn't a storage heater we just turn it on when we want and get instant storage. We're with Eon and In the midlands (will also attach photo) can anyone estimate how much it is going to cost to have TWO of these 1000w heaters on for 3 hours a day? We've put our total electricity cost as £80 a month and don't want to go over that. As I said we don't have gas it's solely electric! Thank you!!! :) we're on a smart meter if that helps (can't access as landlord has key)
