One of very few wall-hung oil-fired boilers on the market, the Grant Vortex Eco Wall Hung range consists of eight condensing boilers: four regular (open vent) and four sealed system models. Both types are available for fitting indoors or out, and with a choice of two heat outputs. The Internal versions are compatible with all of Grant's EZ-Fit flue systems, so they can be fitted almost anywhere. Find out if Grant boilers are reliable, and loved by heating engineers and customers alike, in our full and independent review.
