When learning about ductless mini-split heat pumps, many clients initially are excited about the energy efficiency offered by the installation of a unit. After they have some time to think about the advantages of ductless mini-split heat pumps, they may begin to wonder just how they work. After all, there is more than one home heating solution promising efficiency — by understanding how heat pumps work, our clients can be confident that heat pumps offer superior energy efficiency relative to other home heating solutions.
Heat Pump 101
Ductless mini-split heat pumps extract heat from the outside air and bring it inside, warming the interior air. This may sound counter-intuitive at first, after all, it’s cold outside in the winter months, when we want heat. How does the unit actually achieve this?
The refrigerant in the heat pump is what makes it possible produce this effect — if you have a kitchen refrigerator, then you already have experience with this substance. If you’ve noticed the coils on the back of your refrigerator, imagine those as part of an exterior heat pump unit. As the outside air moves across these coils, any existing heat energy is attracted to the coil, because heat always flows from areas of high temperatures to areas of low temperatures. In essence, the refrigerant captures the heat.
From Outside Air To Inside Comfort
As the heat moves through the system, it warms existing liquefied gas, producing vapor. This vapor travels to the interior compressor unit, which has a fan. The fan blows the heat out into the room and, voila!, you have comfortable, enveloping interior heating. You can keep the system running continuously without worrying about sky-high energy bills, because the system works best as it stays constant.
In the summer months, the system is reversible, meaning you get a fully-functional air conditioning (AC) unit for no additional cost. Forget unsightly window units or expensive central AC.
Energy Efficient Heating and Cooling
Ductless mini-split heat pumps are more energy efficient, all things being equal, than other conventional home heating solutions. Because they are not producing heat — they are moving heat — they offer those with electric baseboard or other inefficient home heating systems a better solution. There is potential for a lot of savings with the installation of a ductless mini-split heat pump.
