How To Size Your Furnace

When purchasing or even replacing an electric furnace in your home one of the most essential things that you have to know is what size it should be. When you have one that is the right size for your home it will be able to run for the allotted time to be able to warm up the entire home and keep it at a comfortable temperature. Having something that will only run for a short period of time is not going to be efficient or effective for your home.

The most standard of furnaces are sold in 10,000 to 15,000 BTU due to the fact that the manufacturers understand that heating is not an exact science – but this comes pretty close to what most people need. People who may be over 20% are fine. Each furnace is sized depending on the kilowatt of power that it consumes. Every Kw is able to produce 3400 BTU’s of heat. Any home that need 52,000 BTU’s of heat will need to divide that number by 3400 to receive the correct Kw number they need. The answer would be 15.29 Kw.

There are many methods you can use that will help you to determine the exact size that you need when in search for the perfect electric furnace. The easiest thing that you could do would be to purchase a system sizing program. This program allows you to enter all of the necessary input construction data of your home. This gives you the most accurate answer.

Another way that you can determine the size is to hire a contractor. They will come to your home and give you an evaluation of the electric furnace to what they think the right size would be. Make sure that you hire a professional who knows the floor plan well and is able to calculate more accurately.

Of course if you think you can handle it you can always do it yourself. All you have to do is measure the square footage of your home and compare it to the heating capacity that you are wanting. Within the warmer regions this is usually around 25 to 30 BTU’s per square foot. Those who live in the colder regions will want it to be around 35 to 40 BTU’s per square foot.
