Homeowners considering switching to a heat pump or a heat pump upgrade from a unit that is older, there is a variety of features available. Over the last twenty years, engineering in heat pumps has continued making strides in efficiency and performance and majority of units today are two times as energy-efficient as models of two decades ago.
By transferring heat energy in your home from one area to another, heat pumps are able to warm and cool the home. In summer, your homes heat pump operates much like central air conditioners, heat being absorbed from household air from an indoor coil that contains compressed refrigerant. The refrigerant takes the heat energy to the outdoor coil where it is distributed into the air. During winter, the heat pumps outdoor coil extracts dormant heat from the air. This heat gets concentrated by the cycle of the compressor and the refrigerant that is hot is taken to the coil indoors, where it gets distributed to warm the home.
Take a look at these features when considering a hat pump upgrade:
SEER and HSPF – Cooling and heating efficiency of heat pumps are expressed by (SEER) seasonal energy efficiency ratio and (HSPF) heating season performance factor. Cooling efficiency is rating by SEER, with 13 being the current minimum. For upfront cost that are higher, heat pumps that are high-efficiency have ratings up to 24. If you live in a climate where there is a long cooling season, utility bills that are lower over time might pay back that initial upfront cost. Heating efficiency is represented by HSPF, with a range presently at 6.5-11. Ratings which are higher are more efficient with heating the home.
Blower which is Variable-Speed – Majority of older heat pumps have air blowers with two-speeds. Greatest temperature efficiency is not produced with this action of on/off. Rooms may get too hot or overcool quickly while the blower runs. When the blower goes off, these temperatures may switch to the opposite extreme. Variable-speed blower heat pump upgrades almost run continuously, at a smaller volume and slower speed. This keeps room temperatures more consistent.
Thermostatic Expansion Valve – Money is saved with this feature by refrigerant flow adjusting continuously to the homes requirements according to the temperature outdoors. This takes the burden of the compressor, reducing wear and tear and energy consumption, while adequate refrigerant is being delivered to warm or cool your home.
Compressor that is Two-Stage – Energy is saved with a two-stage compressor by dropping to an output mode that is lower when heating or cooling requirements of your home permit. Energy is wasted using 100% compressor output in moderate temperatures. Output is shifted to approximately 65% when applicable, when your homes temperature is sensed by the two-stage compressor.
Copper Coils and Tubing – Heat is transferred more efficiently with copper and are not as fragile as coils that are aluminum. Heat transfer volume is enhanced by the grooved interior of the copper coils.
When looking to upgrade your heat pump, be sure to look for all these features to be sure you get the best money saving and energy efficient investment for your home.
