A Keston boiler system is a wall mounted boiler that has the energy efficiency rating of an A +. The C36 model has independent controls and will get the water hot in no time. These boilers are lightweight and have a full central heating modulation. The hot water flow is the highest that is available on the market that is nearly twice during the peak rate.
The Keston boiler has an intelligent control system so it will not shut down for no reason. The pump and the fan get exercise when during times when the boiler is not being used to keep it running in top shape. The boiler is less likely to seize up and stop working. This boiler can extend the flue for up to 60 m so it can be stored in small areas and ventilation is not a concern.
