How To Determine The Size Of Furnace For Your Home

When it's common cold outside (even in LA), you need the correct furnace to heat your home evenly and efficiently. A furnace tin only do its task properly if it's the correct size for the space it's heating. Likewise big and it will switch on and off frequently, too small and it volition run constantly. Neither is ideal.

A pocket-sized furnace will pb to loftier energy bills, uneven heating, and a shorter lifespan. Not to mention the fact that you'll probably still exist common cold. A furnace that'southward as well big, on the other hand, might make parts of your domicile uncomfortably hot while leaving other areas unproperly heated. This constant cycling in short bursts could wear information technology out quickly. To avoid these issues, learn how to cull the right sized furnace for your home.

How practice I decide the right size furnace for my home?

Gas furnaces are differentiated past their BTU capabilities. BTU stands for British Thermal Units. One BTU represents the amount of energy required to heat i pound of h2o past ane degree Fahrenheit. To decide the proper BTU you'll demand for your domicile's heating, you lot'll have to do a little math.

First, find out the square footage of your dwelling.

Yous should exist able to find this number on the paperwork you lot received when y'all purchased your dwelling. If you tin't detect that, you lot tin calculate the square footage yourself.

Start by measuring the length and width of each room in your abode. Multiply the length and width of each room together to become the foursquare footage of that room. So simply add together together the square footage of all your rooms.

Don't include rooms that don't have ductwork or rooms you don't plan on heating, similar garages or sunrooms. Most furnace size charts operate under the assumption that your ceilings are eight feet high. If your ceilings are higher or lower, make changes to your adding accordingly.

Determine which climate zone you live in.

The United States is divided into different climate zones, each with its own BTU per foursquare pes recommendation. To heat a dwelling in Minnesota takes more than BTUs than a home in Florida. Living in California, your furnace won't have to exist heavy duty.

If you're working with Mike Diamond, and then your home lies in Zone ii – a hot-dry or mixed-dry out climate zone. In Zone ii, you need 35-40 BTUs for each square foot of your abode.

Calculate the furnace size yous'll need.

To determine the number of BTUs yous demand to estrus your home: multiply your square footage by the zone heating factor. If your dwelling is well insulated, apply the lower number. If your home is not well insulated or has other factors that may make information technology harder to oestrus, use the higher number.

For instance: in a well-insulated L.A. home that is two,000 square feet our equation is:

2,000(sq ft) X 35 (zone factor) = 70,000 BTUs

For this home, we need to install a furnace with a rating of 70,000 BTUs. But nosotros have one more step to finding our perfect furnace.

Calculate your new furnace's actual output.

When you shop for your new furnace, you'll notice two numbers on it. The showtime is the amount of heat information technology will produce in BTUs. The second number is its efficiency rating. To calculate the actual BTU output of any furnace, multiply the two numbers. For instance, a furnace capable of 100,000 BTUs at an efficiency rating of 80% volition actually produce 80,000 BTUs of heat:

100,000 10 80% = fourscore,000

Make sure y'all calculate this properly before installing a furnace that is too small for your space.

Reference a furnace size chart.

Y'all can also compare your home's square footage to a furnace size chart. There are a number of different furnace size charts out there. These charts requite comparisons betwixt home square footage and the BTUs needed to heat it. It's not as authentic as computing it yourself. Most charts follow guidelines similar to these:

A 1,200-square-foot home will require between 35,000 and 75,000 BTUs A 1,500-square-foot home will require between 45,000 to xc,000 BTUs A one,800-square-foot home will require between 55,000 to 110,000 BTUs A 2,100-square-foot dwelling house will require between 65,000 to 125,000 BTUs A 2,400-square-foot home will require between 75,000 to 145,000 BTUs
