Awards & Accreditations
Introducing Grant’s patented heating technologies
Unlike traditional oil-fired boilers, the 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.
