Offering first-class comfort in a compact, wall-hung appliance small enough to fit inside a standard kitchen cupboard*, the Keston 30C combination boiler enables heating and hot water to be controlled independently, ensuring maximum comfort and efficiency.
The Keston C30 combination boiler can be sited almost anywhere in the home, without the need for a separate tank. And because it connects to the unique Keston twin-flue system, the boiler can be situated anywhere up to 21 metres from the flue outlet, helping to provide further flexibilit y when required.
Fully modulating, the 30C provides excellent energy savings, making it the perfect choice for new or replacement installations alike.
