I have a Viessmann 100-w 26kw system boiler connected to a 250 litre invented cylinder. It runs a 4 bedroom detached house with 3 heating zones and uses the hot water sensor to run the cylinder permanently from the boiler. It was fitted with a Magnaclean which is cleaned annually, the condensate trap has been cleaned out just once in 6 years. This boiler has needed virtually no maintenance, it has never failed, it has had nothing spent on it parts wise. I hear about various quality makes but seriously this is the best boiler I have ever had. Quiet, compact and reliable beyond expectations.
