When did Vaillant change the look of Ecotec range, I thought it was 2012ish? Just serviced a 637 according to the boiler info the customer had it was fitted 2007. They have just moved in so have inherited the boiler and paperwork. It's the first one I've seen, was quite impressed, the pipe work was awful though, like someone threw it at the wall and some of it happened to stick!
