Air Source Heat Pumps
Grant's Aerona and Aerona 290 air source heat pumps use R32 and R290 refrigerants for high efficiency. These MCS-approved systems qualify for government grants and feature smart controls. Ideal for reducing carbon footprints while maintaining consistent home heating.
HVO Oil Boilers
Vortex Pro and Eco oil boilers are HVO-compatible, allowing conversion to renewable biofuel. Available in floor-standing, wall-hung, and combi models with up to 10-year guarantees when installed by certified professionals.
Hybrid Systems
VortexAir hybrid systems integrate heat pumps with oil boilers for optimal efficiency. This solution provides flexibility during transitional seasons while maintaining low carbon emissions and energy costs.
Underfloor Heating
Uflex and Uflex MINI underfloor heating systems offer even heat distribution. Compatible with renewable energy sources, these systems maximise living space and provide comfortable floor temperatures in new and retrofit builds.
Solar Thermal Systems
Grant's solar collectors, WinterSol, and CombiSol systems harness solar energy for domestic hot water. These systems reduce reliance on conventional boilers and qualify for ECO4 scheme incentives when paired with compatible controls.
