We have tried to express the advantages and disadvantages of each type in the below sections.

Selecting Keston

Selecting a model of boiler requires consideration of the type and condition of a place you are heating.  Age of your home is important, system setup, number of radiators, insulation grading, dwelling type, if your home is an apartment what floor you are on is important. Storage radiators verses radiators with convector fins also matter. Furthermore if you have a system fault you will need to troubleshoot , fault find and almost always replace parts

Typical problems

Keston Boilers have common problems like most other boiler types. Most problems are caused by not proper installation (performed not by Keston authorized service team). Sometimes old condensing boilers fail to fire because pressure switch breaks, you will hear then characteristic ‘buzzing’ noise. This noise never occurs when the boiler fires correctly and in normal operation (boiler fires, ignites, heats water and then stops). Fixing the switch solves issue for next couple of years.  Other problems include: the central heating and hot water are not working the same time for Combi boilers and priority always goes to the hot water, combustion seals leaking, hose failures, leaking diverter valves and/or pressure sensors. Almost all boilers will get trapped air or low water pressure within the system. This common issue can be easily overcomed by bleeding the air from the radiator. What’s more additional water can be put into the system via mains valve.

Warning!!! It is a criminal offence to work on a gas appliance if you don’t have proper qualifications. If there is an issue with your boiler and you need help pls call a Keston national service team, who has knowledge, experience, proper qualifications and is Gas safe registered
