As far as I can see Alan, as long as your boilers comply with the test regulations , they can be classified as new boilers. As long as they can pass the new boiler test,, I can see no problem in why the boilers cannot be registered. I have a mate with a similar problem and this is the line he is going down. If you join a new club, their inspector can ask you to strip the boiler for a full visible exam. This I can understand if you do not have any boiler history, having seen some silver soldering of boilers!!! Either way Al, if you don't run your boilers in public , ...(why not???), and having seen your standard of engineering, there is no problems.... unless your house burns down and then your stuffed!!!!. Dave..(looking forward to testing his stationary boiler in the next few months)......Cool here in Brum though I can see some pssible problems with some of my boilers, as several have never had a test (apart from the ones I give them), and are, in some cases, many years old. However, as they are never run in public, it will only affect me if I sell the models concerned. Alan ___________________________________________________________ NEW Yahoo!
