﻿The savings of combining heat pump and condensing boiler
Glow-worm’s Hybrid domestic heating system is claimed to cut heating bills by up to 30% when replacing an existing standard-efficiency boiler and carbon footprint by up to 40%. Larger savings are possible if the boiler is an old heavyweight model. The Hybrid system combines a boiler and air-to-water heat pump.
The control system automatically selects the most effective heating method at any particular time to deliver the most cost-efficient hating and hot water — whether that fuel be electricity or gas.
