How to Determine the Right Size of a Heat Pump
Remember the children’s story, Goldilocks and the Three Bears? It’s been around for nearly 200 years but it’s still relevant today. At DeZiel Heating & AC, it reminds us of heat pumps. That’s because when purchasing a new heating system, it’s very important that the unit is the right size for your home. Not too big. Not to small. Just right.
How a heat pump works
A heat pump works by transporting heat from the outside to inside, or the other way around. This is very different than a furnace, which creates heat through combustion and distributes it around the home.
There are many benefits of a heat pump. For starters, this type of system is very energy efficient. Also, the same unit that’s used for heating your home in the winter can also be used to cool it down in the summer. Heat pumps can also be quieter when running and make it easier to keep the home’s air at the right humidity level.
Why size matters
Having a heat pump correctly sized ensures the until will deliver maximum performance, reliability, and efficiency. If the heat pump is too small or large, you can experience significant temperature differences around the home, ineffective humidity control, and higher energy costs. The unit will also need to work harder to do its job, which will result in frequent on/off cycling, increased wear and tear, and shorter service life.
The good news is there is a standard method for sizing a heat pump in any home. It’s called the Manual J Heat Load Calculation.
Using the Manual J Heat Load Calculation
Recommended by the EPA, the Manual J Heat Load Calculation is a more sophisticated way to size a heat pump than just going by square footage of the home. An HVAC professional will evaluate and use a number of factors, including:
- Size of home
- Regional climate
- Airflow from room to room
- Duct size
- Window air leakage
- Duct air leakage
The calculation determines how many BTUs are required to heat your home. This will allow you to select the correct size for a heat pump.
