Flow hopes that the centre, which cost £250,000 to develop, will train up to 3,000 engineers a year.
The investment comes as the company prepares to launch its new electricity-generating boiler to the UK market in January 2015.
The training facility was opened on 08 October by Graham Evans, MP for Weaver Vale. Guests were given a guided tour and a first look at the new micro CHP boiler.
Tony Stiff, ceo of Flowgroup, said: “We are delighted to officially open the training centre in Runcorn and the whole team is looking forward to educating engineers on every aspect of our boiler. The large investment we are making reflects our ambitions, and believe our new, game-changing boiler will quickly gain significant market share. We look forward to welcoming engineers through the door.”
