Grant boilers combine choice, quality and service to be an installer’s favourite oil boiler brand
G1 Installers, Marshall Heating Ltd, completed the installation of a Grant Vortex Eco Utility oil boiler in the village of Benenden, Kent, in October this year and we caught up with them to discover more about why this boiler, and Grant’s other Vortex and VortexBlue models, are the preferred brand of oil-fired boilers for this installer.
