Stewart Purchase, the joint managing director of the boiler manufacturer Viessmann has resigned from his post to set up his own firm.
Purchase is to set up his own company SP Energy Associates, which will focus on renewable energy systems and training on them for commercial and domestic applications.
Purchase was sole managing director of Viessmann until last year when he began holding the post jointly.
Working for Viessmann has given Purchase a good knowledge and insight into renewable technologies.
A family-owned company since 1917, Viessmann has a turnover of 1.3 billion Euros.
