Explore a number of other housing related calculators as well as hundreds of other calculators addressing finance math health fitness and more. A british thermal unit or btu is a unit of measurement of energy. Get a professional opinion. 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.

Desired temperature change x cubic feet of space x 133 btus needed per hour. Depending on the size of your room the number and type of windows and what. If you don t determine the proper size of heater you should be looking for you run the risk of your heater not effectively heating the space or overheating it causing the room to be either drafty or stuffy. Multiply that result by the temperature increase you calculated in step 3.

Our btu british thermal units calculator will help you to work out the heat requirement for your room and recommend the number of radiators you will need to comfortably heat it. Furnaces are rated based upon how much thermal heat they can produce per hour btu h while air conditioners are rated based upon how much thermal heat they can. As a general rule of thumb for every person over an initial 2 people add 600 btus. Calculate the btus you need.

We often refer to the british thermal unit as a btu but the rating is actually the btus per hour or btu h. Btus are british thermal units the unit in which radiator efficiency is measured. For example a 300 square foot room typically requires 7 000 btus to maintain a comfortable temperature while a 1 000 square foot room requires 18 000 btus. Conversely if you oversize your heater with too many btus you may be spending more money than necessary on your heating bill.
