Heat Pump System: An Energy-Efficient Solution for Your Home

If you are looking for an energy-efficient heating solution for your home, a heat pump system may be worth considering. A heat pump captures heat from outside and moves it into your home, providing a cost-effective and eco-friendly way to heat your home during colder months.

What is a heat pump system and how does a heat pump work?

The key to how a heat pump works is the relationship between pressure and temperature. When the pressure of a gas increases, the temperature also increases. When the pressure decreases, the temperature decreases. The gas used in heat pumps is called a refrigerant, and the heat pump uses electricity to compress this refrigerant, increasing its pressure and therefore its temperature.

The heat from the refrigerant is then transferred to your home through the heat exchanger, cooling the refrigerant down a little. The refrigerant is then allowed to expand, which cools it even further. This cooling makes it possible to absorb more heat from outside, starting the process again. The heat delivered to the heat exchanger can then be used to heat your home using a central heating system or warm air.

How efficient are heat pumps?

One of the biggest advantages of using heat pumps for homes is their efficiency. The amount of heat produced by a domestic pump is greater than the amount of electricity used to power the system. The amount of heat produced for every unit of electricity used is known as the Coefficient of Performance (CoP). For example, if a heat pump has a CoP of 3.0, it will give out three units of heat for every unit of electricity consumed.

The Seasonal Coefficient of Performance (SCoP) or Seasonal Performance Factor (SPF) is used to show the efficiency of the heat pump across the whole year. Heat pump installers must calculate the SPF based on their system design for your home, such as a diagram of a system, which demonstrates how the heat pump should perform given the average temperatures at your location and other details such as the size of your radiators.

Will installing a heat pump lower your heating bills?

Several factors affect the cost-effectiveness of a heat pump system, including:

  • Fuel being replaced and its cost
  • Electricity tariff
  • Type of heat pump installed
  • Efficiency of the heat pump
  • Design of central heating system
  • Location and its average air or ground temperatures throughout the year

For example, people using gas boiler may find heat pumps are slightly more expensive to run unless particular attention is paid to ensuring maximum efficiency of the heat pump in the heating system by using best practice radiator or underfloor heating design. However, utility and heat prices continue to fluctuate, as do running costs.

Are they eco-friendly?

Heat pumps are an eco-friendly heating solution for your home. As they capture heat that is already present in the environment, the system itself does not burn any fuel and therefore emits no carbon dioxide.

Heat pumps also produce less noise pollution compared to traditional heating systems. With no combustion or fuel storage required, heat pumps offer a safer and cleaner alternative to other heating systems.

What is the cost of a heat pump system in the UK?

The cost of a heat pump system in the UK can vary depending on the type and size of the system. A ground source heat pump system can cost between £20,000-£35,000, while an air source heat pump system can cost between £2,000-£9,000. It’s important to note that these costs do not include installation, which can add significantly to the overall cost. Additionally, maintenance costs should also be considered, with a budget of around £250 per year for servicing a heat pump being the recommended amount. The UK government, however, is offering £5,000 grants to help households install home heat pumps and other low-carbon heating systems as part of its plan to reduce carbon emissions.
