I've been using the Worcester 24i combi boiler for 13 years since the house was built and I have found out that I'm qualified for the nPower home energy saving scheme which I had a technical survey done yesterday and the engineer said he will replace my current boiler with the Baxi Duo-Tec 28kW combi boiler, is the Baxi Duo-Tec a well known boiler and better than my current one?
