|Heater Shop BTU Calculator|
This calculator aims to accomplish your heating job in ONE HOUR or less.
Depending on the size of your room or the temperature you're aiming for,
this can sometimes result in a much larger heater than you really wanted.
If you can run the heater for longer and wait for the room to warm up
or simply turn on the heater earlier you can use a much smaller heater.
You can use a 1500 Watt heater in a 12x12 room with 8 foot ceilings.
And use the same heater in a 15x15 room with 10 foot ceilings.
The 12x12 room will just reach the perfect temperature more quickly.
To make the calculator report smaller heater sizes for you
simply reduce your desired temperature increase.
