Common questions about heat pumps

Q. How do heat pumps work?
A. Heat pumps consist of two primary components: the outdoor compressor unit and the indoor air handler, known as the evaporator. These components are connected by a conduit that houses the tubing, power, communications and condensate drain lines, facilitating their seamless operation.

A heat pump functions by extracting heat from the outdoor air. When the refrigerant undergoes a pressure drop and transforms into a vapor, it becomes colder than the surrounding air. Because heat energy naturally moves from hot to cold, the refrigerant absorbs heat from its surroundings. Once it has absorbed all available heat, the outdoor compressor raises the refrigerant’s pressure, causing it to transition into a hot liquid. This highly heated refrigerant is then transported to the indoor coils, where the blower releases the captured heat into your home.

Q. Do I need to replace my heating system if I install a heat pump?
A. Highly efficient heat pumps are an excellent choice for improving your existing furnaces and boilers. They are commonly used to provide additional heat in spaces that are either not heated or inadequately heated by your home’s heating system, such as garages and workshops. With their superior performance and efficiency, heat pumps offer a reliable and effective solution to give you optimal warmth and comfort in these areas.

Q. What size of heat pump do I need for my home?
A. Several factors affect the necessary size of a heat pump. These include the local climate in Western Connecticut, which determines the number of heating days per year. The square footage of your home, the quality of its insulation, the number and location of windows, and any heat-generating appliances — like a clothes dryer — also play a role. It is important to consider these factors to ensure optimal heating efficiency. That’s where utilizing the expertise of seasoned professionals, such as those at Leahy’s Fuels, is invaluable. We thoroughly assess every aspect of your home, taking into account your heating requirements specifically for heat pumps.

When it comes to heat pumps, size matters. If your unit is too large, it will consume excessive energy for heating and cooling, undermining the potential energy savings. On the other hand, a heat pump that is too small won’t adequately meet your home’s heating and cooling requirements. It will have to work harder and turn on more frequently, leading to higher energy costs and premature wear and tear, ultimately diminishing your return on investment. Therefore, finding the right-sized heat pump is crucial for optimizing efficiency and maximizing savings.
