Vaillant is celebrating the production of its one millionth ecoTEC high efficiency condensing boiler for the UK market, at its factory at Belper in Derbyshire.
The one millionth boiler produced was an ecoTEC plus 831 high efficiency combination boiler.
Vaillant is awarding £1,000 of holiday vouchers, shared equally by the householder and the installer of the one millionth ecoTEC boiler.
As every boiler has its own unique serial number, the winner will automatically be identified when registering their Vaillant boiler guarantee either over the phone, online or by post.
