Biomass Boilers, Air source & hybrid boilers

Grant VortexAir Oil Hybrid

The Grant VortexAir is a hybrid unit that couples together a Grant VortexBlue condensing blue flame oil-fired boiler with our Aerona3 inverter driven air source heat pump (ASHP), with just a single flow and return connection into the house.

What is the benefit of using a hybrid?

A hybrid unit enables the optimum use of both an inverter driven air source heat pump and a blue flame condensing oil boiler, throughout the year, as the ambient air temperature (and consequently the heat demand of the building) changes, thus providing the most efficient use of both the renewable and nonrenewable energy sources.

Grant Aerona³

The Aerona³ R32 air source heat pumps are Grant’s greenest and most efficient generation of heat pump technology.

Compact in size and highly efficient, the Aerona³ heat pumps provide homeowners with a renewable solution to fulfil their heating and hot water requirements. Using the more environmentally friendly R32 refrigerant, an Aerona³ heat pump achieves high performances to effectively keep properties warm while also helping households to lower their dependency on fossil fuels.


Biomass is a renewable, low carbon fuel that is already widely available throughout the UK.

Grant Biomass boilers installed by Wolf Heating are clean and more efficient than most A-rated condensing boilers and tend to last 2 or 3 times as long.

They are easy to operate and control and provide high levels of efficiency with very low maintenance needed.
Fully automated biomass boilers offer the the latest technology and the highest levels of heating comfort with convenience.
