This external version of the Grant high level and vertical flues is compatible with all Grant Vortex models. Available in a modular form, the system can cater for most installations. The flue is manufactured from a high grade stainless steel, to ensure longevity.
The Grant Vortex Pro outdoor combination oil boiler features internal frost protection, a 24 litre expansion vessel, neon diagnostic indicators and a factory-fitted condensate trap, together with the conveniently factory-fitted, multi-directional flue - and all of this has been designed to make installation and servicing easier. With larger than normal heat exchangers, the hot water performance of this high-efficiency combi boiler is vastly increased. The two very accurate electronic temperature controls allow the boiler to operate in condensing mode on central heating and instant hot water production can be maintained.
The latest Grant Vortex Pro internal combination oil boiler features a 24 litre expansion vessel, neon diagnostic indicators and a factory-fitted condensate trap - all designed to make installation and servicing easier. With larger than normal plate heat exchangers, the hot water performance of this high-efficiency combi boiler is vastly increased. The two very accurate electronic temperature controls allow the boiler to operate in condensing mode on central heating and instant hot water production can be maintained. In addition, a low system pressure cut off switch protects the combi boiler in the event of system water loss.
The quiet Vortex Eco wall mountable oil boiler from Grant features the latest, highly efficient stainless steel Vortex heat exchanger and turbulator baffle system - providing some of the highest efficiencies on the market. Pre-plumbed, this boiler can be used with low level, high level and vertical flue systems - providing extremely flexible options for installation situations.
