Gas boiler losing pressure


I would expect a Gas boiler to last way longer than 8 years. more like double that - at a minimum. That is assuming it is serviced regularly.
 
I would have expected longer than 6 years - I would not have expected 16 years though.

Technology changes. For example, new boilers has a flow valve instead of a pressure valve, so they don't cut out when pressure drops.

I get a 5 year warranty with the new boiler. and they install the magnetic filter which seems to make the whole system more efficient.
