Frequently Asked Questions

Your questions, answered.

What is the Grant VortexAir Hybrid?
It is a combination of a high efficiency condensing blue flame oil boiler and an air source heat pump, interconnected using a control system, such that they operate together as a single unit.
How does it work?
The control system on the hybrid unit monitors the ambient (outside) air temperature and allows only the heat pump to operate when the air temperature is high enough for it to meet the heat demand of the building on its own. At lower ambient air temperatures the boiler will operate alongside the heat pump, providing a boost to the flow temperature. When the ambient air temperature falls lower still, the boiler is operated at its full output at a higher flow temperature to enable the hybrid unit to meet the higher heating demand of the building.
