Most models feature a battery back-up that will remember your settings during a power cut. The only exception is our fascia mounted MT10 Mechanical Timer, which would require a simple adjustment following a power cut.

This is the siphon fill programme. When switching mains power on to the boiler it will fire at a minimum output for up to 20 minutes. The central heating function will be run at a minimum output during this programme.

A condensing boiler can extract more heat from the fuel it uses than a standard efficiency boiler. It also means that less heat is lost through the flue gases. The term 'condensing' boiler refers to the fact that the boilers produce condensation from time to time. Condensing boilers use heat from exhaust gases that would normally be released into the atmosphere through the flue. To use this latent heat, the water vapour from the exhaust gas is turned into liquid condensate. To make the most of the latent heat within the condensate, condensing boilers use either a larger heat exchanger or a secondary heat exchanger. All Worcester Bosch condensing boilers are known as 'Greenstar' boilers.
