Heat Pump Week: Heat pumps and the environment

Heat pumps and the environment

In the search for a sustainable future, heat pumps are becoming ever popular in the UK. As we look to reduce our carbon footprint and embrace energy efficiency, heat pumps are becoming a popular choice for homeowners and businesses alike.

Heat pumps are devices that transfer heat from one place to another, making them an efficient way to heat homes. Unlike traditional heating systems that generate heat by burning fuel, heat pumps move heat from one place to another. This process makes heat pumps over 300% more efficient than traditional heating systems such as gas and oil boilers.

There are mainly two types of heat pumps: air source and ground source.

  • Air source heat pumps (ASHPs) extract heat from the outside air, even in cold temperatures, and transfer it indoors. They are an excellent option for the UK climate due to their ability to work efficiently in varying weather conditions.
  • Ground source heat pumps (GSHPs) use the stable temperature of the ground to provide heating. They involve installing pipes underground, making them more suitable for properties with enough outdoor space.

Heat pumps play a crucial role in reducing the carbon footprint. By using renewable energy sources, they significantly lower greenhouse gas emissions compared to traditional heating systems. This shift towards cleaner energy will help the UK meet its net zero targets and contribute to a healthier planet.

Heat pumps reduce carbon emissions

Heat pumps are the perfect solution for reducing your carbon footprint and reducing carbon emissions. Whichever kind of heat pump you ultimately opt for, the environmental impact is undeniably positive.

In the UK, 18% of our greenhouse emissions come from the carbon footprint of heating homes. This is one of our biggest sources of emissions and is mostly caused by gas boilers. The average UK home making the switch from a traditional g-rated gas boiler to a heat pump could make reduce their CO2 emissions by 77-86% over 15 years compared to a gas boiler, based on UK Government guidance according to Carbon Brief.  So, in practical terms, the average UK household could save over a tonne of CO₂ every year just by switching to a heat pump. 

Heat pump efficiencies

One of the biggest advantages of heat pumps is their energy efficiency. They can achieve efficiencies of over 300%, as they produce more energy than they consume. This high efficiency can lead to lower energy bills, making them a cost-effective investment for homeowners. We’ve got a comprehensive post on heat pump efficiencies that you can find here

Heat pump grants 

As the UK government aims to phase out gas boilers and promote renewable energy, heat pumps will become more prevalent. Incentives and grants are available to encourage installations. Schemes such as the Boiler Upgrade Scheme gives eligible homeowners access to a £7.5k grant to help with the costs of a new heat pump. We’ve covered all the different types of heat pump grants available to UK homeowners in this comprehensive post.
