I know how frustrating a situation like this can be. I once had a troublesome boiler which no engineer could fix. As a last resort, I set fire to my house, destroying the entire contents and claimed on the insurance.
I later installed a Ferroli Syitbo x24, which I consider to be a top of the range appliance.
