Are old heat pumps efficient?
Unlike a furnace or central air conditioner, a heat pump is required to provide you with warm air in the winter and cold air in the summer. Since your heat pump fulfills a demanding task, it will not last for 30 years. On the other hand, the bad news is that a heat pump becomes less efficient as it becomes older.
How old is heat pump technology?
The truth however is that heat pump technology has been established for more than 150 years and the first ground source heat pump was brought into use more than 70 years ago.
How often do heat pumps need servicing?
If you use your system year-round to heat and cool, EES recommend that you have your heat pump serviced every year by a heat pump technician. If you only use it in winter to heat your home, or in summer to cool your home down, then a service every two years should be fine.
When to use an air source heat pump?
The air source heat pumps can extract heat from the air, even when the temperature drops to -15°C. An air source heat pump is an excellent choice for the ones looking out for premium heat pumps of their everyday heating requirements. The standard heat pump consists of an outdoor and an indoor unit.
Where does the heat from a heat pump go?
When there is a call for heat, the heat pump will turn on the fan in the outdoor unit to begin the process of extracting heat from the air outside of your home. The refrigerant line carries this heat to the indoor unit, which then transfers the heat to the air inside of your home via a fan inside the wall cassette.
How is the power from a heat pump credited back to you?
In many homes, power generated by the array that is not used in the home is credited back to you by your electric utility company and is used to offset your electric bill at the end of each month. Most homes will still have an electricity bill for power used overnight, during storms, or during periods of high use such as very hot periods of summer.
How does the refrigerant work in a heat pump?
The refrigerant line carries this heat to the indoor unit, which then transfers the heat to the air inside of your home via a fan inside the wall cassette. In cooling mode the process is reversed, transferring heat out of your home and returning cool air to the inside. What is the benefit of having a heat pump?
How often should an air source heat pump be serviced?
Air source heat pumps use well-established technology, and may have a working life of 20 years or more [22]. But just like a boiler, you should get your air source heat pump professionally serviced – every two or three years – to make sure that it’s still working at its best.
When is it time to replace your heat pump?
It may be time to call a professional contractor to help you make a change if: Your heat pump or air conditioner is more than 10 years old.

When to replace an air conditioner with an Energy Star?
Your heat pump or air conditioner is more than 10 years old. Consider replacing it with a unit that has earned the ENERGY STAR label. Installed correctly, these high-efficiency units can save up to 20 percent on heating and cooling costs.
Which is more efficient an electric heat pump or air source heat pump?
An air source heat pump produces more heat energy than it uses in electricity. So while a modern gas boiler is more than 90% efficient – and electric heaters are 100% – air-source heat pump efficiency can be three or four times higher [9.1][9.2]!
