I'd kill for a $130.00 electric bill. But with a 2,500 sq ft. house, 3 Tv's, 3 computers, two tanks and summer temperatures in the 100's my bill is usually around $250.
I have close to $800 total volume of tanks at the time was 450 gallons, with 1400w of heaters, and 500+W of lighting on 10 hours a day, and a dehumidifier on 24 hours a day. Plus we had 3 adults and a 1 year old in the house almost 24 hours a day. This was also the coldest month of last winter at -40 for two weeks.
I have 2 many tanks and to many filters ect.. Electric bill is $550.00 and up a month. 3300 sqft house 3 story, heat pump 1 year old, house 10 years old, and over insulated by +3 walls to +10 roof above code. All electric, no gas.
mine stays under $90 in a 1br/1ba apt. it didnt go up much once i set up my tanks. im adding another 55g and 125g and moving to a 2br/2ba next month so im sure it will go up a bit, mainly due to the fact of a bigger apt.
