I had a qoute to install a central heating system in a 3 bedroom, two lounge house which involved eight rads powered by a vokera unica 28he gas boiler. While the work was being done the fitter said he had a new model boiler that would cover the pipes and look neater in the kitchen and all the tech specs were the same. The boiler fitted was a vokera syntesi 25E and I have now seen on the vokera website that this is a discontinued model. I am also worried my shower will not work on a 25KW boiler. Is this a rip off or is it acceptable? Thanks for your help.
