You may know about heat pumps as an air conditioning solution for homes that do not have ductwork, a situation that is common in older homes and businesses. A lack of ductwork makes adding central air conditioning prohibitively expensive. Heat pumps are a great alternative to those costs as well as to the noisy and inefficient window units, which are also unsightly from both inside and out, which block light and let in dust, pollen and bugs. They can also be a security risk.
What you may not know is that heat pumps are also great for home heating solutions. If you’re building a home and want to add high-efficiency heating and cooling without installing ductwork and large furnaces or boilers and central air conditioning units, mini-splits are a perfect solution. They can also provide heating and cooling to places not served by your home’s existing HVAC system, such as home additions, enclosed sun porches and finished attics.
With a heat pump, you can zone your home’s heating and cooling for maximum energy efficiency.
Hotels, inns and bed-and-breakfasts are turning to heat pumps as a way of providing individualized heating and cooling to each of their guest rooms. It’s more energy efficient, as unoccupied rooms don’t need to be heated or cooled as much as a room with a guest staying in it.
Q. How do heat pumps work?
A. Heat pumps have two major components: the outdoor compressor unit and the indoor air handler, which is also called the evaporator. A conduit — containing lines for the power and communications and the tubing for the condensate drain — connect them.
Here’s how it works for cooling: Refrigerant enters the compressor, which compresses the refrigerant, as its name implies. The refrigerant is delivered to the condenser, where it gives up its heat. The heat is transferred from the device into the air outside. The refrigerant is now a liquid and is sent through the tube to the evaporator. It absorbs heat from the indoor air that passes over the evaporator coils. The cooled air is then released into your home.
This is how it works for heating: In the winter, the closed-loop heat-pump system is reversed. The refrigerant accesses heat from the outdoors, rather than taking it from within the house.
When the refrigerant pressure drops and it becomes a vapor, it gets much colder than the air outside. Because heat energy flows from hot to cold, the refrigerant absorbs heat from the surrounding environment. After the refrigerant absorbs all the heat it can, the outdoor compressor pressurizes the gas into a hot liquid. The extremely hot refrigerant is carried to your indoor coils, where your blower is used to release the heat into your home.
Q. Do heat pumps produce enough heat for an entire home or business even here in Central Maine?
A. Heat pumps can heat a home or a commercial building if they are correctly placed and sized. That’s where AFC’s experience and expertise come in handy. We’ll make sure your heat pumps are installed for efficient home heating. Today’s high-efficiency heat pumps are rated to work in temperatures as low as -15° Fahrenheit.
Q. Do I need to replace my heating system if I install a heat pump?
No. High-efficiency heat pumps can be used to complement an existing heating system, and they are often utilized for supplemental heating.
