SEDBUK A-rated boilers installed

The Worcester Bosch Greenstar range of boiler is the one most specified boilers due to the reliability and the fact that they fall into SEDBUK A-rated range, meaning that your new boiler will use less energy. Generally these boilers are over 90% efficient.

SEDBUK energy-rating classification

Power-flushing the existing system

This is a process of removing all electrolysis and debris from the existing system via a power-flushing machine so that the manufacturer's instructions are met. A corrosion-inhibitor is also added on completion to prevent future build-up.

Room thermostats and thermostatic radiator valves installed

To meet with building regulations the system requires a room thermostat and thermostatic radiator valves on at least the bedroom radiators. If there is no room stat on the existing system a wireless digital room thermostat is installed to prevent cables being ran. Thermostatic radiator valves give you the option of setting room temperatures separately.

Notification to Gas Safe on completion

Once your system is installed, by law, we must self certify the work to the local authorities via GAS SAFE. A letter of confirmation is then sent to you, from them, confirming the installation meets current legislation. Our GAS SAFE number is 28931.
