Oil Boiler Replacement


Herstmonceux, Sussex


Replace oil boiler. Install heat pumps, full distribution system and Solar PV system.


Cost £31,000 - Saving/Income £61,000* Payback time 8.8 years

Our customers were stuck with their oil fired boiler, with the belief there was no alternative for the heating and hot water for their 16th Century home

Our team carried out a full SAP assessment, and designed a system that would cope with the heat losses involved in such an old building.

We installed a full cental heating system, using specially designed low temperature highly efficient radiators.

The system comprises of 2 x 11kW Danfoss AQ heat pumps, which are designed to work in tandem.

The expected savings are as much as 40% over their previous oil boiler system.

We installed a 3.8kW Solar PV system at this property on a barn – which is off setting the running costs of the Heat Pump and on target to give a total income/saving of £1,643.00.
