The Keston S30 has an efficiency rating of 89.5% and an ErP A-rating for heat, meaning that although this system boiler is not the most efficient boiler on the market, it could still help lower your energy bills, depending on your current heating system.
With an output of 30kW for central heating, this system boiler can comfortably heat a medium-sized up with up to 20 radiators. However, if you feel that your home has a higher demand for central heating and hot water, the Keston C35 35kW Combi Gas Boiler may be better suited to your home. On the other hand, if you're thinking about changing to a combi boiler, the Keston C30 30kW combi gas boiler is a great option.
System boilers are ideal for homes with a high demand for central heating and instant hot water. This is thanks to the additional hot water storage cylinder which is installed alongside the boiler unit itself. This hot water storage cylinder will keep unused heated water in a sealed tank, ready to be used when you need it.
Keston boilers are typically used in compact spaces such as smaller flats/properties in locations such as London. This is because Keston boilers offer a twin flue system which makes every job easier. To give you maximum flue flexibility, you can run the flue vertically or horizontally from an elevation of 1.5 degrees and the flue can be extended up to 27 metres from the boiler.
This allows for hassle-free and easy installation and means that your new boiler can be installed in the most practical and convenient space in your home.
