A furnace BTU (British Thermal Unit) is the measurement of heat or energy per unit of energy. The BTU was first used in the United States. The original unit of measurement was the Btu per square foot, which was then shortened to the term BTU. This led to the development of the American measurement system to its current format, which is based on feet square feet. Since this BTU measurement is based on the method of feet of area, it will be used here.
To determine your furnace BTU, simply multiply the furnace size by five. For example, if you have a half-inch pipe, the calculation would be: 15000 * 3.5 = 75000. For refrigeration, you need a BTU for each cubic foot. This calculation is for the method used for refrigeration, although you can use this method for any furnace in order to calculate its BTU. Some homes that have single-stage furnaces do not actually have one BTU. This can be measured, if you notice, when a meter is in the home. This number can be found with an electrical power supply to determine the actual number of BTUs your furnace will produce.
If you are going to be selling your home, you should take the value of your home into consideration when determining the BTU. If you do not want to be stuck with inaccurate numbers, it is a good idea to hire an expert to estimate your home’s value. However, if you are planning to live in the home for more than one year, you should invest in a furnace and have it installed by a professional company in order to have the true BTU of your furnace.
