Pump testing .
Have you ever wondered how a gas engineer would determine weather your system needs a new circulation pump or not ?
Pump testing preferred method varies from one firm to another , but only one fullproof method is the best.
A central heating Circulation pump circulate specially hot water from point A inlet to point B outlet .
To test effectively if your central heating Circulation Pump does its job is to test the temperature 50cm at the inlet and 50cm out the outlet; there should be very little to no drop of temperature difference. If this is not the case ,then your central heating Circulation Pump needs changing for new.
