It seems approaching my electric usage has be on the rise and I can not figure out what is going on. I own gas heat and a gas hose heater. Last winter my usage average 900 kw/month. Was up to something like 1000kw.mo in the summer near two small window component ac. Last month my bill had us up to 1200 kw/mo, this month it is 1500kw/mo and for the two weeks since my ultimate bill I am already up to 1000---which makes me deliberate next bill will be for 2000kw!! I do own a small cermaic heater within a bedroom upstairs--but the room is 10X10 and is heated by the gas to 60 and I try to keep it 70 surrounded by there...so I am only heating another ten degree with that space heater....what gives?
Answers:    hold the utility check for a faulty meter, or they may newly be estimating , not reading the numbers.
Sounds like something within your home needs maintanence. Most plausible the gas heater have a fan specifically blowing the hot air. Is the filter clogged? If the disciple is struggling to move air it will use more and more liquid.
