The challenge
The property's size and mixed insulation levels made a full heat pump replacement challenging without major radiator upgrades.
Our solution
We installed a Worcester Bosch hybrid system — a 7kW heat pump handles 90% of heating needs, with the existing gas boiler providing backup on the coldest days.
The result
Gas usage dropped by 80%, and the homeowners enjoy lower bills with the peace of mind of a backup system during extreme cold.
“The hybrid approach was perfect for our older house. We're using far less gas but still have the backup if we need it.”
— Richard & Emma Davies
