As part of its Build A Boiler competition, Worcester Bosch is offering HVP readers the chance to win a Greenstar 30i combi, built at the factory by HVP editor Jennie Ward

Nine lucky installers visited Worcester, Bosch Group’s factory this summer and walked away with a brand new boiler made using their own fair hands, after testing their skills on the manufacturer’s factory floor.

As part of its ‘Build a Boiler’ competition, Worcester invited the winners to experience its manufacturing process first-hand as they constructed their very own Greenstar i boiler.

The installers were taken to one of the manufacturer’s four ‘lean’ assembly lines and given the chance to get hands on with the 623 parts and 441 process steps that go into each one of its boilers.

The winners then worked against the clock in a final manufacturing challenge, with the time closest to Worcester’s production line standard of 120 seconds also winning a Wave internet-connected controller. Every boiler constructed on the line was then fully checked and quality tested, before the day concluded with a tour around the company’s all-new factory and facilities.

Installer Neil Brown, of Neon Heating and Boiler Services in Hereford, said: “I do servicing for a living, so to come on the production line and get my hands in there was great – I loved it. Normally I install Greenstar CDi Classic boilers, so now when I come across a Greenstar combi boiler, I’ll know exactly where everything is.”

Swansea-based Dan Williams of DW Plumbing & Gas Services, added: “It was really good, and very informative. What the guys do on the assembly lines is unbelievable. Just seeing all the materials go together and the numerous tests each product goes through was fantastic.”

Matt Wright of Matt Wright Plumbing & Heating, near Leamington Spa, added: “The fact that I knew when we packaged the boiler up that I’d made it, and it was going to go in my house, was very exciting.”

Martyn Bridges, director of marketing and technical support at Worcester, said: “We want installers to feel special whenever they come to our headquarters for training or a site tour. This was a fantastic opportunity to do just that, while inviting installers to take a look at the extensive checks and manufacturing processes that go into all of our boilers.”
