Why join the hybrid revolution?


The revolutionary new VortexAir has been developed by Grant's R&D Team and combines the award winning Grant Vortex boiler and features the latest blue flame technology with a new Aeronał inverter driven heat pump.

This innovation allows the householder to choose between a combination of the two most cost effective forms of fuel "oil and renewables" ensuring that they are never without heat and fuel bills are kept to a minimum.

The Grant VortexAir joins the benefits of an air source heat pump with the latest blue flame oil boiler technology, offering homeowners the best of both worlds.

Seamless Changeover

If a householder already has an oil boiler and is thinking of changing to a heat pump, the VortexAir allows them to make the change seamlessly without the added cost of having to replace radiators or possibly being without heating while the heat pump is being installed. The boiler can be fitted immediately and any additional installation work that the heat pump requires can be carried out over the following days.

It is estimated that the heat pump will be used for about 60-70% of the annual heating requirement, allowing the oil boiler to only come on when the temperatures drop so low that it become inefficient to run the heat pump.

Benefits of an Air Source Heat Pump

With the recent fluctuations in price and supply of fossil fuels, air source heat pumps offer both an environmentally and economically sustainable alternative. Home heating in the UK accounts for around 30% of CO2. The heat source used by Grant Aeronał heat pumps is entirely renewable which helps reduce the amount of harmful greenhouse gases being released into the atmosphere and, in doing so, lowers the carbon footprint of the home.

Blue Flame Oil Boiler Technology

The Grant Vortex oil-fired boiler is renowned for its high efficiency and reliability, making it the perfect back-up heat source. The VortexBlue boiler models incorporate the latest blue flame technology, a Riello RDB Blu burner with low NOx emissions, and are leading the way in oil heating appliances. This is the reason why Grant have combined this appliance with an Aeronał to create the VortexAir.
