What size room will a 20000 BTU heater heat?
To determine the number of BTUs per square foot that you need to heat a room, simply multiply the square footage by 20 BTUs per square foot. For example, if a room has 1,000 square feet, you would require 20,000 BTUs to heat it.
How many Btus does it take to heat a cubic foot of air?
One BTU will raise temperature 1 degree per 55 cubic feet, so divide by 55 (720,000/55).
How many BTU in a heater?
Average BTU Ratings. A typical furnace is rated at 100,000 or 80,000 BTU per hour, but furnaces might be as small as 40,000 or as large as more than 200,000 BTU. A 90 percent high-efficiency rated at 60,000 BTU will deliver about 54,000 BTUs per hour of heat energy to your home.
How do you calculate heater size?
Follow these steps to calculate heater size. Measure the length, width and height of each room you want to heat. Multiply the length of a room by the width and the height to learn the total cubic feet of area. A room that is 10 feet long, 12 feet wide and 12 feet high would be have an area of 1440 cubic feet (10 by 12 by 12).
How many BTU to heat a room?
Calculate the total number of BTUs required to heat the home. For each room, multiply the BTU per square footage times the square footage of the room. For example, a home located in Zone 5 with poor insulation would require 60 BTUs per square foot. Therefore, a room that is 300 square feet will need 18,000 BTUs (60 x 300).
How many BTU to heat?
A standard that is used by heating and cooling equipment companies is to provide at least 25 to 30 Btu of heat per square feet in the home for a moderate to warm climate. A mid-sized home of 2,000 square feet would need approximately 50,000 to 60,000 Btu to heat it properly.
