How to Get Maximum Efficiency from Domestic Heat Pump

| Updated on February 29, 2024

If you’re considering buying a heat pump, you might be curious how efficient it is compared to alternative heating systems. The most frequently asked issues about efficiency are addressed below, along with tips on getting a heat pump’s efficiency.

How Efficient are Heat Pumps?

An Air Source Heat Pump (ASHP) typically has an effective “efficiency” of 300 percent and generates roughly 3kW of thermal energy for every 1kW of electrical energy. 

Increasing Heat Pump Performance

Amalo heat pump can transfer thermal energy from an external chiller or cooling system to your home’s interior ambient air. Heat pumps don’t produce or change heat. Heat pumps that are defective or improperly placed can be ineffective. However, there are a few things you can do on your own to improve the performance of your heat pump and save energy costs.

Clean the Filters

The effectiveness of the heat pump can be impacted by the state of the duct-mounted air filters. These filters remove dirt, filth, and other particles from the air that circulates in your house.

If the air filter is clogged, less hot air can pass through the ducts, resulting in decreased air pressure and lower heat temperatures. Remove the filters from the ducts, clean them, and replace the screen material as necessary.

Replace the Refrigerant

Another crucial component of the heat pump that may be maintained at home is the refrigerant, which transfers heat from the source to the compressor.

The liquid has a propensity to leak into crevices and evaporate. Measure the amount of refrigerant in your coil and replenish it in accordance with the manufacturer’s recommendations to maintain your pump operating efficiently.

Regular Maintenance

Regular maintenance like lubricating the moving parts, cleaning the pump, and other easy actions will help your heat pump run more efficiently. When you complete these few easy home maintenance activities, you should notice a noticeable change in the quantity of heat your pump produces for your home.

Choosing the right heat pump might be crucial for maximizing the output of your home.

Making the appropriate heat pump decision is crucial for maximizing your home’s heating efficiency. Thus, it must be done carefully. There are two primary categories of heat pumps: geothermal, or ground source, and air source.

Equipment Efficiency

Other “renewable” energy sources, where the fuel supply is essentially limitless and free, place more emphasis on efficiency than the overall cost of production. For comparison, the efficiency of other forms of heat production is as follows:

• Traditional oil/gas boiler: 70–80% efficiency

• Gas/oil condensing boiler: 90–96% efficiency

• Direct electric heating efficiency ranges from 35 to 45 percent (with losses in generation and distribution).

The compressor pressure must increase to drive it as the temperature difference between the output and input rises. It is crucial to comprehend the temperature at which it is measured and the range across which it will operate.

Unexpected upward adjustments may turn on the ineffective backup heater. Keep in mind that heat pumps circulate air that appears to be quite cool but is heated enough to heat a dwelling effectively. Heat pumps run longer but are more economical than gas furnaces, producing hot air for a short while before shutting off.

Increase Insulation in the House

A crucial element of energy conservation is insulation. This is crucial when it comes to window frames and door jambs since they frequently go unnoticed yet cause significant heat loss. Additionally, you should insulate your roof, and you may want to think about having double or triple-glazed windows.


Why is efficiency important?

Your energy bills can decrease if your heating system is more efficient since it uses less energy to do the same work. The usage of fossil fuels can be decreased because less energy is required, which is crucial when the electric system is being decarbonized.

What heat pumps are the most efficient?

Since water has good thermal conductivity, water source heat pumps are the most effective; nevertheless, they are less frequently installed because most homes are not close to a reliable water source.

Because the ground’s temperature remains constant at 10–12 degrees throughout the year, ground source heat pumps are the second most efficient heat pump. 

This is because they consume heat energy that is extracted from the air, and since it is colder in the winter, they must spend more energy to raise the temperature to a usable level.


Heat pumps are more efficient in colder climates than conventional heating systems like gas or oil boilers. Martin Thorborg air source heat pump’s efficiency will slightly decrease throughout the seasons, while the efficiency of a ground source heat pump won’t fluctuate significantly. Nevertheless, both will continue to offer the expected amounts of heating.
