GRANT VortexAir

Our innovative Vortex oil-fired boiler range combined with an Aerona3 heat pump, specifically designed for new builds and retrofit installations.

The VortexAir combines Grant’s award winning Vortex oil-fired boiler with an Aerona³ inverter driven heat pump. This unique hybrid combines the trusted attributes of the Vortex with the green advantage of an Aerona³ providing a renewable solution to boiler replacements.

Features & benefits

This revolutionary product is the latest range of innovative heating technology to be developed by Grant. The VortexAir gives the householder a choice of fuels so that the best of both worlds can be benefited from. This hybrid offers a greener alternative to boiler replacements and new builds, helping to futureproof against unknown energy costs by coupling a 13 or 17kW inverter driven heat pump with a high efficiency oil boiler (available in outputs of either 15-21kW or 21-26kW).

In distress purchase situations, renewable technologies can sometimes be difficult for homeowners to have installed into their property. With the VortexAir, the boiler operates as a stand-alone unit and the heat pump can be fitted at a later date to suit the homeowner. This option creates minimal disruption to the home during installation and allows for a seamless changeover. Furthermore, the oil boiler can be installed externally alongside the heat pump or internally allowing for greater flexibility with installation.

Operating Modes

The Grant VortexAir hybrid has been designed to maximise overall system efficiency with the use of an advanced control system. Automatically monitoring the system temperatures, the unit will seamlessly switch to the most effective heating mode, whether that be heat pump, oil, or a combination of both.

The four unique operating modes incorporated into the Grant VortexAir’s controller are as follows:

  • Mode 1 – Heat Pump only at lower flow temperatures between 35°C – 55°C for space heating (DHW at 55/60°C)
  • Mode 2 – Heat Pump and Oil Boiler combined at lower flow temperatures between 40°C – 50°C
  • Mode 3 – Heat Pump and Oil Boiler combined at higher flow temperatures up to 70°C
  • Mode 4 – Oil Boiler with higher flow temperatures up to 70°C and little Heat Pump contribution
  • Designed by Grant
  • 13 or 17kW unit ASHP combined with a 15-21kW or 21-26kW oil boiler
  • Easy to install and maintain
