What does BTU mean for patio heaters?

This refers to the amount of thermal energy or “heat” an appliance produces. It’s measured in British Thermal Units (BTU). A higher number means the unit is more efficient and will produce more heat.

What does BTU mean for gas heater?

The heat output of gas heater is generally measured in British thermal units (BTUs), a unit of energy. To figure out the heating capacity of a gas heater, you can simply multiply the heater’s BTU rating by the heater’s surface area and divide the result by 1000 to get Btu/sq. ft.

What does BTUs mean for wood stove?

Wood burning stoves and fireplaces produce heat by sending a stream of burning wood up the flue pipe. Hot air rises, and cooler air is pulled in to replace it, so a wood burning heater’s heat output is dependent on the amount of combustion air that enters the flue. In order to increase the heat output, increase the amount of combustion air. The amount of air required to support combustion is called the “burner air requirement.”

What does BTU mean for propane heater?

A gas furnace’s BTU rating is determined by its heating capacity. It’s expressed in British thermal units (BTUs). One BTU is equivalent to one calorie of heat, which is the amount of energy required to increase the temperature of 1 pound of water 1 degree Fahrenheit.

What does BTU mean for portable heater?

A higher heating capacity will raise the temperature faster, meaning you’ll spend less time waiting for your heater to heat your patio to a comfortable temperature. You’ll also spend less money on fuel and the heater will last longer. It will take less fuel to heat the same amount of area as a heater with a lower heating capacity.
