I have had the Baxi duo tech for 2 years and have had nothing but trouble with it - keeps showing error E1 and no heating or hot water - the gas men have been out several times in fact this week they have been out every day and I am getting fed up with it. The have replaced the expansion thing and still woke up to the E1 error, man that came today said that I may need to have my underfloor pipes checked for a leak and I will have to pay for this - help please
