Condensing boilers, like all modern ones including those made by Worcester Bosch, have a condensate pipe. This pipe vents harmful gases from your property. As a rule, if your boiler problems relate to a loss of pressure, you have a leak. Sure, it might not be visible, but it’s there somewhere.

For older Worcester Bosch boilers, problems with ignition may stem from an issue with the pilot light. That’s because these older models aren’t equipped with electronic ignition, and thus rely on the pilot light to fire up. Create a DHW demand andfully open a tap. Measure thevoltage across the two tags onthe modulating gas valve.Is it over 10Vdc? If you find that this light isn’t working properly — and neither is the boiler — it could be due to these root causes: Note: Once you’ve fixed the water leak, make sure you top up the boiler’s water levels so that the water pressure is around 1.3 bar) Are you still having problems with your Worcester Greenstar boiler and need a boiler repair or new boiler quote?But note that repressurisation a temporary fix.

NOTE: This failurewould cause coldwater at the flowoutlet and the boilerwill cycle on theheating control stat. Product Information: There are two kinds of heat exchanger that can be within your heating unit, the primary heat exchanger and the secondary heat exchanger. The primary is present in almost all boilers and it allows the heat to be transferred from the burner to the water within the system. The secondary heat exchanger only appears on combination boilers and allows the heat to be transferred from one closed system to another.

Based on installing a new A-rated condensing boiler in England, Scotland and Wales with a programmer, room thermostat and thermostatic radiator controls (TRVs) in a gas heated detached home from an older G-rated boiler with a programmer and room thermostat.
