How do you measure a gas boilers efficiency
Hopefully a simple question how can you tell the efficiency of a boiler one that's been installed for 15 years?

To measure it will need lots of super expensive tech kit and likely the removal of the boiler to a suitable laboratory to do the measurements.
15 years just a little worse?
I do wonder how you can prove the efficiency in real life not on a test bench even when they are new let alone up for replacement or repair.

Obviously from that you can't tell how efficient e.g. the heat exchanger is so there will be some losses.
