For the want of a horse shoe nail

Had the central heating boiler service yesterday. A small grommet (10p) had a fault, the system is old so no replacements are available, we need a new boiler £2000 . The engineer came today actually we need a new two pipe system not an inefficient one pipe system £6000. And all for the loss of a boiler grommet.

O.H. Says never mind we'll be lovely and warm next winter......... If we can afford the gas.
