Wouldn't you need to remove the 4 allen bolts to take pump head right off, so you can see the impeller turn (or not)?Nock off the two valves both side of pump loosen 4 allen screws run pump see what happens
Don't get that bit. Only works if the heat input is known. Maybe gas flow is measured, or a relation between gas valve and flow is assumed, and h/ex efficiency assumed.The flow rate through the boiler is monitored by recording the differential between the boiler water temperature and the return temperature.
