• Safety: These pumps are much safer to use than traditional gas fired boilers.

• Low maintenance: These pumps only need a small amount of maintenance.

• Savings: Ground source heat pumps can be expensive to buy initially. But the Renewable Heat Incentive (RHI) scheme provides funding to help support households with a pump. Over time you could see amazing savings in your energy bills, more than making up for the initial investment. You can learn more about the RHI scheme in our ground source heat pump cost guide.
