Key Takeaways

  • Key factors to consider when choosing a heat pump include power output, efficiency ratings, noise levels, and warranty, ensuring it meets your home’s heating and cooling needs efficiently.
  • The Viessmann Vitocal is named the most efficient heat pump for 2024 due to its high performance, cost-effectiveness, and value for money.
  • The Daikin Altherma 3 is regarded as the best heat pump for cold climates in 2024, capable of operating efficiently at temperatures as low as -28°C.

Factors to Consider When Choosing a Heat Pump

The process of selecting the most suitable heat pump includes several considerations to ensure it fulfills your home’s heating and cooling needs. These include:

  • Power output
  • Efficiency ratings
  • Noise levels
  • Warranty

Understanding these elements can help you select a heat pump system that not only fits your budget but also provides optimal performance and comfort.

Power Output

A decisive attribute of a heat pump is its power output, which influences the system’s capacity to heat or cool your home efficiently.

Measured in kilowatts (kW), the power output must match the size of your home and its specific heating needs. For instance, larger homes require heat pumps with higher power outputs to ensure adequate heating and cooling throughout the year.

Choosing a heat pump with a suitable power output is imperative to prevent problems like underheating or inefficiency due to an excessively large system.

For example, the MasterTherm UK BoxAir Inverter covers a range of power ratings from 2-7 kW to 7-22 kW, making it flexible for various home sizes.

Similarly, Vaillant flexoTHERM models offer options up to 19 kW, catering to larger homes’ needs. Ensuring your heat pump’s power output aligns with your home’s requirements can lead to better energy efficiency and lower energy bills.

Efficiency Ratings

Efficiency ratings play a significant role in gauging a heat pump’s overall performance and cost-effectiveness.

These ratings, such as the Coefficient of Performance (COP) and Seasonal Coefficient of Performance (SCOP), measure the energy efficiency of the heat pump.

A higher COP or SCOP indicates that the heat pump produces more heat per unit of electricity consumed, leading to lower energy consumption and reduced utility bills.

For instance, the LG Therma V boasts a COP of up to 4.90, signifying high energy efficiency. Air source heat pumps typically range around 300% efficiency, though this can vary by model.

Understanding these metrics can help you choose a heat pump that maximizes energy savings, contributing to more sustainable living and significant cost savings over time.

Noise Levels

Although frequently neglected, noise levels become a significant consideration while selecting a heat pump. A quieter operation ensures a more comfortable living environment and minimizes disturbances to both homeowners and neighbours.

For example, the Samsung EHS Mono HT Quiet operates at a low noise level of 50 decibels, roughly equivalent to the sound of a quiet refrigerator, making it ideal for residential settings.

Comparing noise levels across different models can help you find a heat pump that balances performance with quiet operation.


A solid warranty plays a vital role in safeguarding your investment in a heat pump. Most heat pumps come with a warranty period of at least 5 years, covering parts and labor.

This provides peace of mind and ensures long-term reliability and support.

For example, the MasterTherm UK BoxAir Inverter offers a 7-year warranty, which is highly valued by users for providing extended coverage and assurance.

Choosing a heat pump with a comprehensive warranty can safeguard against potential issues and unexpected costs.

Grants & Costs

As the government continues its push to net zero, there are ongoing heat pump grants available to homeowners in the UK. This means that you can offset the cost of an air source heat pump or other renewable home heating system when replacing an old gas boiler.

The Boiler Upgrade Scheme, for example, means homeowners can get up to £7,500 currently towards a brand new heat pump and installation. Ensuring you choose the best option for you and your home is therefore important to ensure the savings can recoup some of the higher initial expense.
