Gas Fireplace Btu Output

Btu british thermal unit is a unit of measurement for heat.

Gas fireplace btu output.

Btu stands for british thermal units. You can find out by measuring the square footage of the area you want to heat and then finding a fireplace with the right amount of btus for the space. This btu calculator will determine what hearth product size is required with only a few steps and information such as square footage sq ft. Since excess heat can be transferred outside the unit is able to burn at a higher btu output resulting in an impressive flame without the extra heat.

It can be used to describe the heat produced by a natural gas fireplace an electric heater or a propane fire pit to name a few. Use this formula to determine which models generate enough heat to warm your room. Multiply all three figures. A btu or british thermal unit is the amount of heat required to raise 1 pound of water 1 degree fahrenheit.

All gas appliances are rated in btu s hr input which is an approximation of the amount of gas consumed on full fire in one hour as expressed in terms of the heat potential of the gas. Natural gas typically is used at 3 5 to 7 inches of water column. A gas fireplace s heat output in btus should match your room size climate and your house s insulation level. The maximum number of btus per 50 cubic feet is 1 000 so the maximum btu rating for your room would be 24 000.

The formula assumes that your house is well. For instance if your room is 10 feet wide 12 feet wide and 10 feet high the result would be 1 200 cubic feet. But how do you know how many btus are right for your home. The number of btus a gas or wood fireplace can generate varies widely depending on the size and model of the fireplace.

Lp is used typically at 10 11 inches of water column. For fireplaces the higher the btus the higher the heat output. Napoleon offers several models with this technology but the bl36nte is a very popular traditional model of fireplace while the l38 is a lower cost linear model that still offers a beautiful. Natural gas 1000 btu ft3 has less btu s per cubic foot than lp liquid propane 2500 btu ft3 5.

The 72 000 btu unit with 85 efficiency has an output of 61 200 btu which is more than the 80 000 btu unit that was less efficient. Therefore either type of fireplace can do the job in most cases. Gas fireplaces have a wide range of heat output from about 7 000 to 60 000 btus. This term has been around for centuries and it is still used to this day as the standard for measuring how much heat is generated by a source.

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.
