All we get this winter is condense pipe blocked-boiler locks out - ok its been financially good but when the regulations changed these boilers were sold as the answer to all bla blah.
The reality is condensing boilers that 'save energy' now need trace heating for the condense, to be undersized to make them reach high efficiency - unable to warm homes properly at -12, they are never going to last 10 years let alone 15 as the old ones used to and you need to spend loads on chemicals and filters to keep them working. Add all the complications that befall combis - diverter valves and low pressure and you have a government led manufacturer created market in unreliable systems that cost too much to purchase and maintain. They cannot be green because the units are headed for the skip after 5 or so years
