Keston - Boiler Efficiency Rating
Keston were born from a parent company back in 1928 to manufacture heating solutions for domestic and commercial settings and by 1998 had become a recognised name in the industry.
Their range of boilers are proudly built and designed in the UK and the ranges mentioned below are all ErP compliant and come recommended by the Energy Saving Trust.
Combi
Small enough to fit inside a kitchen cupboard, this range of compact boilers allow for heating and hot water to be controlled independently. Available in outputs of 30kW and 35 kW, there’s a couple of options whether you’re looking for something brand new or a replacement.
Available with a 5 year parts and labour warranty as standard, this can be extended to 7 years when installed with a Keston filter, the latter is only available until the end of 2018 however.
System
At an output of 30kW, the Keston System S30 boiler is a heating solution that will heat your home from just a single unit. Without the need for an extra tank, this System boiler can be positioned just about anywhere in the home. The standard warranty of this boiler is also 5 years although it can be extended to 7 subject to the same terms as the Combi boilers above.
How Much Does a Keston Boiler Cost?
The two Combi boilers are available for roughly £1100 to £1200 while the System boiler tends to be at the lower end of that range. This price range doesn’t include the cost of installation, which will vary depending on the engineer carrying out the work.
