In June 2019, the UK government released plans of their target to be Net Zero by 2050.This commitment means that the UK has been one of the first G7 nations to be committed to a fixed date, following in the footsteps on non G7 countries such as Finland and Norway. There is no denying that heated pumps have a large roll to play in adopting low carbon heating systems. Although heating still poses the biggest question for low carbon emissions, air source and ground source heating pumps are a viable option to help the UK meet its new target, and are growing increasingly popular. Due to new restrictions, all new builds and extensions are now required by law to be built with low carbon heating systems.
Air Source vs Ground Source Heat Pumps
Our homes account for 14% of carbon emissions, resulting in it being one of the biggest challenges in the UK for decarbonisation. The International Energy Agency (IEA) has meant that has already recommended a ban on new gas boilers from 2025. Air source heating pumps take in air which is then blown over tubes filled with refrigerant, turning it from a liquid into gas. Using electricity, the pump compresses this gas which increases the temperature – and then in turn this can be used to heat you home. Ground source pumps extract heat using underground pipes, a refrigerant is pumped through these pipes to absorb heat, with the heat pump compressing the fluid and releasing it at a high temperature, to use towards heating your home.
Heat Pump Installation in Existing Homes
Heat pumps can be installed at any home, however to ensure you get the best results it is important that the home is well insulated. Old or poorly insulated homes may need more heat than a pump can produce. A qualified heating engineer will be able to advise you if this is something that would be suitable for your home.
Legislation and Planning Permissions
Ground source heating pumps are unlikely to need planning permission as they are generally considered “permitted development” as they have limited aesthetic impact. In Wales and Northern Island, you will need planning permission for air pumps. In England you don’t, providing you meet the criteria on the government website.
Who Can Install Heat Pumps?
Research has found that over 52% of builders are not ready for the changes in building regulations, regarding energy efficient buildings. Why not book onto a course to learn the new legislation, and be prepared for the changes that are going to take place. They can guide you on how to fit energy efficient heaters, providing tailored advice, support and training.
