Gas unit heater sizing calculator.
Furnaces are rated by the amount of fuel energy consumed when running called input btu.
Multiply that result by the temperature increase you calculated in step 3.
The british thermal unit or btu is an energy unit.
We are currently upgrading our site to better serve you.
This btu calculator will determine what hearth product size is required with only a few steps and information such as square footage sq ft.
Due to the upgrade our website inventory is unavailable at this time.
It is approximately the energy needed to heat one pound of water by 1 degree fahrenheit.
The heating capacity of a furnace is measured in thousands of btu british thermal units.
The result rounded off to the nearest thousand is the total btus or heater size you need.
If your garage heater is too small it will take a very long time to reach your desired comfort level if at all.
If you re still unsure which system size is right for you please e mail us or call our toll free number at 1 866 862 8922.
Calculate how many btus you need to heat a room or even a house with a wood burning pellet or gas fireplace insert or stove.
When shopping for heaters many people make the mistake of choosing the wrong size for their actual needs.
Answer a few questions about your energy source and garage and the garage heater calculator free tool recommends models that will do the job.
First multiply by 133 the total cubic feet of area determined in step 2.
1 watt is approximately 3 412 btu per hour.
Calculate the btus you need.
Different furnaces of the same input btu have different efficiencies measured in percentages.
Our free garage heater calculator takes the guesswork out of selecting a garage heater.
A little under sizing or over sizing is fine just don t over size by more than about 20 of your heating requirement or short cycling can occur which wastes energy and reduces your comfort.
1 btu 1 055 joules 252 calories 0 293 watt hour or the energy released by burning one match.
Once you ve decided to heat your garage or workspace it is essential to select the correct unit size for the space.
Take the guesswork out of garage heater sizing.
Sizing a garage heater is a critical part of the process.
In the example this would be 40 000 btus.
