Why are my radiators cold when my Keston boiler is running?

The most common causes are low boiler pressure, trapped air in the radiators, stuck thermostatic radiator valves, a faulty circulation pump, or sludge buildup. Check the pressure gauge first and repressurise if below 1.0 bar. Then try bleeding the radiators to release trapped air.

What is the Benchmark commissioning checklist for Keston boilers?

The Benchmark commissioning checklist is a document completed by your Gas Safe registered installer when commissioning your Keston boiler. It confirms the boiler has been installed correctly according to manufacturer guidelines and Building Regulations. The completed checklist should be left with the boiler and is required for warranty validation. Keep it safe with your boiler documentation.

Can a Keston boiler be installed in a cupboard or enclosed space?

Keston boilers can be installed in cupboards or enclosed spaces provided there is adequate ventilation and access for servicing. The boiler requires clearance around it for maintenance. Room-sealed boilers take combustion air from outside via the flue, so the cupboard does not need air vents. Always consult a Gas Safe registered engineer for installation requirements.

How do I adjust the hot water temperature on my Keston combi boiler?

On Keston combi boilers, the domestic hot water temperature is adjusted using the hot water temperature knob on the control panel. The temperature can be set between approximately 40 and 65 degrees Celsius. A setting of 50 to 55 degrees is recommended for safety, as this prevents scalding while being hot enough to prevent bacterial growth.

What are the flue clearance requirements for a Keston boiler?

Flue terminals must be positioned at least 300mm from windows, doors, or other openings. They must be at least 600mm above flat roofs, 75mm below guttering, and maintain 2 metres above ground level where possible. A terminal guard is required if the 2-metre height cannot be achieved. Only a Gas Safe registered engineer should install or modify boiler flues.
