Reducing carbon emissions and transitioning to renewable energy sources are crucial steps in combating climate change. One effective way to achieve this is by air source heat pump installation. These innovative heating systems harness heat energy from the outside air, even during colder periods, to provide efficient and eco-friendly heating for homes and businesses. 

In this blog, we will explore the benefits and installation process of air source heat pumps, as well as the criteria to consider when choosing an installer. By the end, you will understand how heat pump installation can help reduce carbon emissions and lower energy bills, while also contributing to a more sustainable future.

The UK government wants to phase out gas boilers from newly constructed households by 2025 in order to achieve carbon net-zero status by 2050. This decision was prompted by the need to reduce greenhouse gas emissions and the impacts of climate change.

What are Air Source Heat Pumps?

Air source heat pumps are a type of heating system that extract heat energy from the outside air, even at temperatures as low as -25°C. They work by utilizing a refrigerant, which evaporates at low temperatures, absorbing heat from the air. 

This heat is then transferred to water, which is used for space heating and hot water. Air source heat pumps can also be reversed to provide cooling during hot weather, acting as air conditioners. The energy efficiency and low emissions of these systems make them an environmentally friendly heating choice.

How do Air Source Heat Pumps work?

Air source heat pumps work by pulling heat from the outdoor air, regardless of the temperature, and transferring it indoors for heating. They consist of an outdoor unit with a refrigerant coil and compressor, and an indoor unit. The outdoor unit absorbs heat from the air, and the compressor raises the temperature for release indoors. 

The indoor unit heats water for various purposes. In warm weather, the process reverses to cool indoors. These pumps efficiently extract heat even in cold climates, offering a greener alternative to fossil fuel systems. They produce fewer carbon emissions, relying on renewable heat energy.

Types of Air Source Heat Pumps: Monobloc vs Split System

When choosing an air source heat pump, it’s crucial to know about two types: monobloc and split system heat pumps. Monobloc units have all components in one outdoor unit, making installation simpler with no indoor pipework. 

However, they may need more outdoor space. Split systems have an outdoor unit connected to an indoor unit by pipework, offering flexibility in indoor placement. They suit spaces with limited outdoor rooms and diverse heating needs. Both types provide efficient heating and hot water solutions, with the decision depending on factors like space, air source heat pump installation preferences, and heating requirements.

Criteria for Installing an Air Source Heat Pump

When considering the installation of an air source heat pump, several criteria come into play:

  • The availability of enough space for the external heat pump and compressor.
  • The compatibility with the existing central heating system or hot water cylinder.
  • The eligibility for the government’s boiler upgrade scheme in the UK.
  • The need for annual service and maintenance to ensure its efficiency.
  • The environmental impact and reduction in carbon emissions compared to traditional boilers.

Location Requirements for Optimal Performance

Optimizing the air source heat pump system requires careful consideration of the outdoor unit’s location. A solid base and protection from high winds are crucial for efficient operation. Adequate spacing around the unit facilitates airflow and service accessibility, contributing to energy efficiency.
