The amount of money spent to operate a heater over the lifetime of the heater is much more than the initial cost of the heater itself. Make an educated decision with our Heater Energy Cost Calculator.
Proper heater sizing yields optimal comfort and operating efficiency. If your heater is too big it will cycle on and off all the time, leading to uneven heating and premature failure. If your heater is too small it will not maintain comfortable temperatures. Use our Heat Load Calculator to figure out how much heat you need.
