Your current heating system is finally on the fritz. It may have served you well over the years, but if it’s frequently breaking down, does not perform as it once did, and/or costs a lot of money to run, a new system may actually be of benefit to you. New heating systems are built to be far more efficient than they were a decade or two ago, as the U.S. government repeatedly sets new standards for HVAC efficiency. And if you think you may need a new air conditioning system as well, then you may be in luck. One of the most efficient heating systems available on the market today is also extremely effective for cooling.
The term “heat pump” is deceptive as it may sound like this is primarily a heating system. However, this is untrue; “heat pump” simply refers to a type of system that moves heat from one area to another. An air-source heat pump, the most common type of heat pump used in homes today, is actually more closely linked to an air conditioner, as it contains nearly all of the components therein. So how does a heat pump also help with heating?
First, let’s take a look at how a heat pump works for cooling. It contains the same components as an air conditioning system. Most notably, there is an outdoor and an indoor fan, the outside compressor, a condenser coil, and an evaporator coil. Refrigerant runs through the inside and outside portions of the heat pump, starting at the compressor, where it’s pressurized and heated so that it can release heat during condensation at the outside coil. Refrigerant then moves inside, where it evaporates and absorbs heat from the air, only to release this heat outside and continue the cycle.
The one component that differentiates a heat pump from a standard air conditioner is the reversing valve. This allows refrigerant to flow in the opposite direction. Now, refrigerant absorbs heat as it evaporates outside and heat dissipates into your house at the inside coil as refrigerant condenses. So what makes this unit so efficient for heating? Simply put, it takes a lot more energy to create heat, as most heating systems do, than to move it from place to place. Therefore, a heat pump can save you a whole lot of money in the heating season.
