Hello! As a professional in the field of home heating and energy efficiency, I'm here to help you understand how to calculate the BTUs you need to heat your house. BTUs, or British Thermal Units, measure the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. When it comes to heating your home, understanding BTUs is crucial for selecting the right heating system that will provide adequate warmth without wasting energy or money.
**Step 1: Determine the Total Square Footage to Be Heated**
The first step in determining the BTUs you need is to figure out the total square footage of the space you want to heat. This includes all the rooms you want to keep warm during the winter months. Make sure to measure each room and add up the total area. Don't forget about any additional spaces like basements or attics if they are part of your living space.
Step 2: Consider the Climate Zone
Next, you need to consider the climate zone you live in. Different regions have different heating requirements due to variations in temperature and insulation needs. The heating factor is a number that represents the amount of heat loss per square foot. For example, if you live in a colder climate, you might have a higher heating factor.
**Step 3: Multiply the Total Square Footage by the Heating Factor**
Once you have the total square footage and the heating factor, you can calculate the total BTUs needed by multiplying these two numbers together. For instance, if you have a 2,500 square foot home and live in a climate zone with a heating factor of 40 BTUs per square foot, you would multiply 2,500 by 40 to get a total of 100,000 BTUs per hour.
Step 4: Factor in the Furnace Efficiency
It's also important to take into account the efficiency rating of your furnace. Furnaces are not 100% efficient, meaning they don't convert all the fuel they consume into heat. The efficiency is usually expressed as a percentage. If your furnace is 80% efficient, for example, it means that for every BTU of fuel it consumes, 0.8 BTUs of heat are produced. You'll need to adjust your BTU requirement based on this efficiency.
Step 5: Choose the Right Heating System
With the calculated BTUs in hand, you can now choose a heating system that meets your needs. It's always a good idea to consult with a professional HVAC contractor to ensure you're selecting the right system for your home. They can also help you with installation and maintenance to ensure your system runs efficiently and safely.

Multiply the total square footage to be heated by the heating factor. If you live in a 2,500 square foot home and a climate zone with a heating factor of 40 BTUs per square foot, you need a furnace with an output of 100,000 BTUs per hour. Take the efficiency rating of the furnace into account.
