What Is Heat Load?

It can be hard to believe in the middle of winter that other items beside your heating system can add to the heat level in your home.

While it may not be a significant amount of heat, it is still heat and needs to be counted, especially when you are planning a new heating installation for your Salt Lake City home. The extra heat you get from different home items, such as lights, electronics and sunlight fall under the umbrella term of “heat gain” and to correctly size a new heater, you’ll need to know what the heat gain of your home is.

Heat Gain vs. Heat Load

We’ve identified what heat gain is, but there are a number of factors that contribute to it:

  • Orientation of your home
  • Number of windows and doors
  • Types of windows and doors
  • Insulation levels
  • Floor plan
  • Number of rooms
  • Number of occupants
  • Square footage

There are a few others that may be considered, but these factors are the crux of it. Once you know how much heat your home gains throughout the day, you can move on to the next calculation: how much heat your home needs to be comfortable, which is the heat load. Many people believe that square footage is the only factor you need to know when calculating heat load; this is not true. Using the same factors above, your trained expert will determine, in BTUs (British thermal units) how much heat your home will need daily to keep you warm and comfortable.

Why is this important?

Installing a heating system that is the wrong size – either too big or too small – won’t just make you uncomfortable; it will be bad for the heating system, too. And without the correct heat load calculation, you may not choose the right-sized heating unit for your home.
