When selecting a new heating system, It’s important to consider the efficiency of heat pumps and their features, along with a few lesser-known factors, that will determine your home comfort and savings. Here’s a breakdown of what you need to know when evaluating heat pumps:
Because a heat pump is a multi-purpose home HVAC system, you’ll need to check out two efficiency ratings: Heating Seasonal Performance Factor (HSPF) for heating, and Seasonal Energy Efficiency Ratio (SEER) for cooling. You can maximize your investment by selecting a high-efficiency system with ratings above HSPF 8 and SEER 14. Keep in mind that systems with higher ratings will provide better monthly energy savings, but they will cost more to purchase initially.
The features included in a heat pump determine its overall efficiency. Advanced features that enhance comfort and savings include:
- Improved refrigerant delivery with a thermostatic expansion valve (TXV), which will meter precise amounts of refrigerant according to the climate’s demands.
- Variable-speed components, like a motor or air handler, which allows the heat pump to use energy wisely and increase home comfort.
- Upgraded design for coils, which generally allow for an overall increase in the surface space of the coil so that it can take on more refrigerant.
While it’s important to consider the efficiency of a heat pump, you should keep the following points in mind:
- Demand defrost capabilities are critical in the winter, which should ideally decrease the process of defrosting to minimize electricity consumption.
- Noise levels are also a factor. Make sure the system meets minimum guidelines, generally below 7.6 bels.
- The position of the unit will also affect noise and efficiency. Make sure it’s located away from windows, and protected from winds.
- The installer should evaluate the position of the indoor coil, as it should generally be positioned upstream of the furnace to maximize efficiency.
