18kw electric furnace


Hi friends.

I've been trying to figure out how much monthly bills will be at a showhome i recently built this winter. From November 15 to December 10th, I had the heat at 50F set, and it used an unbelivable 143kw so far in that time period (18kw furance). My question is if i set the furance to say 65F or higher instead would it basically use the same amount of hydro anyways since its still always going to go on and off??

143 kWh is unbelievably low for that kind of heat over 25 days.

Setting your thermostat higher will result in higher consumption of energy. Simple physics -- you will need more BTU's therefore it will make your electric bill higher.

Are you sure you have the correct numbers in you posting? 143KW means your 18KW furnace only ran 8 hours in a 25 day period. When you say an unbelievable 143KW is that unbelievably high or unbelievable low?

The Multiplier is 10. So its about 1800 kW.h/Month that the furance used set at 55 degree's. In a brand new R2000 insulated house.

Seems high to me, unless setting it at 72 or so won't end up actually being that much more.. I guess i'm lucky its only .65/kW.h

with a 10x multiplier, 1430 kWh sounds about right. Be prepared to use much more than that if you set the thermostat higher.
