As more homes and businesses in Yeovil and Somerset look to reduce energy bills and carbon emissions, heat pumps have become a popular alternative to traditional heating systems. At The Heat Works, we regularly help customers decide between the two main types: ground source heat pumps (GSHP) and air source heat pumps (ASHP).
Both are highly efficient and renewable, but they suit different types of properties and budgets. In this guide, we compare ground source vs air source heat pumps so you can make the right decision for your home.
Both air source and ground source heat pumps work by extracting heat from the environment and using it to heat your home and hot water. Instead of burning fuel, they transfer ambient heat using a refrigerant cycle, making them much more efficient than traditional boilers.
Homes with limited outdoor space, smaller gardens, or retrofit projects in towns like Yeovil, Sherborne, or Martock.
Properties with larger gardens or land, new builds, or homes planning a full heating upgrade in rural areas around South Somerset.
