Grant developed their first oil-fired Outdoor Module in 1986 and although the concept was new to the oil market, it quite quickly became a popular addition to Grant’s boiler range. It is therefore appropriate that Grant has again taken the lead with the introduction of three new Grant Vortex Condensing oil-fired Outdoor Modules, with outputs between 15 and 46 kW (50-157,000Btu/h) and gross seasonal efficiencies of 95-97%.
This high efficiency Outdoor Module range has some unique features including multi-directional flueing options, high quality external powder coated paint finish, built-in boiler frost protection, mains isolating switch and a test switch.
