Grant VortexAir Range

a+++ Heating a Water

5 Year guarantee*

The VortexAir Hybrid incorporates the highly efficient Aerona³ R32 air source heat pump with a low NOx Vortex oil boiler.

The cleaner oil-fired boiler technology combined with the green credentials of the Aerona³ heat pump results in an innovative hybrid heating solution. With the VortexAir, renewable technology can be introduced into the home while also having the peace of mind that comes with the back-up heating provided via the boiler.

Case Studies

Why hybrid heating?

Why hybrid heating?

Each year, thousands of older oil boilers are changed, most often as distress purchases and requiring a quick replacement heating solution. In these situations, there is often little opportunity to choose an alternative fuel source, such as a renewable technology, because heating and hot water needs to be quickly restored to the property. This is where Hybrid heating technologies can step in.

A hybrid, such as the Grant VortexAir, bridges the gap between renewable energy and situations when a traditional fuel source is the most obvious solution – it allows homeowners to start their transition to renewable heating without the added cost of having to resize and replace radiators and without the prospect of being without heating for a prolonged period of time. Joining the benefits of an air source heat pump with the latest blue flame oil boiler technology, the VortexAir unlocks the potential of renewable heating for properties where it was previously not thought possible.
