Chris Chapman - Founder
Chris Chapman and family moved to Nelson in 2004. Having run a successful plumbing and heating business as an Accredited CORGI gas installer and Registered Plumber installing central heating in the UK, Chris found it hard to believe that hydronic central heating was not standard requirements New Zealand homes at the time.
Although it was not Chris’s intention to get involved in the central heating business again, he found old habits die hard and his enthusiasm returned. He launched Chapmanz in 2005.
Chris is a certifying gas fitter - Reg No. 21080. And a registered ETA wood pellet boiler installer.
