Grant Vortex Pro XS 26kW Combination Boiler Oil ErP

The latest Grant Vortex Combi models feature internal frost protection, 24ltr expansion vessel, neon diagnostic indicators and a factory fitted internal condensate trap (this can be sited externally if preferred), all designed to make installation and servicing easier. The Grant Vortex Pro Electronic Condensing Combi boilers are available in three sizes – 21kW, 26kW* and 36kW.

Grant Vortex Pro Combi’s have larger plate heat exchangers which due to their low water content and great surface area, vastly increase hot water performance. Mixing valves on the unit are pre-set at 50°C, which accurately control the hot water draw off temperature from the boiler. They also include a low system pressure cut off switch, enabling the combi to protect itself in the event of system water loss. Additionally, there are two very intelligent electronic temperature controls which allow the boiler to operate in condensing mode on central heating, whilst keeping the instant production of hot water.

New Combi XS models

As many oil boilers are sold as replacement products for older inefficient appliances, which tend to be smaller in physical dimension, the size of a new boiler plays an important part in the decision of what product to fit. The new Vortex Pro Combi XS is a compact 26kW boiler, developed as an addition to the existing range which means it can replace an older oil-fired combi, as it is only 515mm wide. This new boiler has almost identical characteristics on both combustion efficiency and domestic hot water performance as its larger version and utilises all of the existing components. The only difference is that the 24 litre expansion vessel, normally located behind the front door of the boiler, will now be supplied as an externally fitted vessel kit.
