Product Details

The Vortex Air is a hybrid oil boiler and air source heat pump launched by Grant UK. The boiler and heat pump are operated together by the built-in ‘hybrid’ control system, as follows:

Heat pump only – when the demand is within the capacity of the heat pump

Heat pump backed up with short bursts from oil boiler when required

Boiler only – automatically takes over when the ambient air temperature drops to a pre-set changeover temperature

Unlike traditional oil-fired boilers the Grant Vortex condensing boiler has a built-in stainless steel heat exchanger incorporating Grant’s unique turbulator baffle system, which cools the gases to a point where the latent heat, normally lost to the atmosphere through the flue, can be usefully extracted.

The additional energy recovered enables the boiler to operate continuously at much higher efficiency levels, resulting in lower heating and hot water running costs.
