Greenstar 4000 – a hydrogen blend boiler

We’re now getting closer to Net Zero targets, and the UK is under pressure to find sustainable solutions to our everyday life activities – including the way we heat our home; hence hydrogen heating is a priority.

Worcester Bosch’s entire gas boiler range can run on a 20% hydrogen blend – so you can be confident that this boiler is future-proof; meaning it can use hydrogen as a fuel source if needed, but it also can run on gas for the time being until the switch.

It’ll always come with one as standard, varies in length, and can be extended for an additional cost. There is only one difference between the two, and that is that a boiler manufacturer’s guarantee is a promise to repair your boiler for a certain amount of time after installation, no matter what the cause. There is no small print that can catch you out if certain things may have caused the boiler to break down. The manufacturer will send an engineer to your home and repair it regardless.

Worcester Bosch is one of the few manufacturers to offer a guarantee rather than a warranty. This is a major selling point and could often be the deciding factor in choosing your new boiler. Enjoy a 10-year guarantee when you buy a Worcester Bosch Greenstar 4000 for additional peace of mind.
