Awards & Accreditations
What is a Combi boiler?
A combi (or combination) boiler produces both heating and hot water from one compact appliance. No additional hot water cylinder is required, and the hot water produced by combis is sent to the taps at mains pressure, which makes combis an attractive proposition, especially when space is at a premium within the home. In addition, homeowners can normally save money and time on the installation of a combi boiler too, as there is less additional components to install.
Grant have internal and external combi models available in the Vortex range.
