2017 thor Km24 equipped with girard 2 tankless. Have never gotten "hotwater." 82F is as hot? as it gets. I've tried set temps from 105 to 124 which is as hi as it goes. No change. Water hook ups or pump no change. Cleaned the pump filter, no change. Monitor comes on shows flame, fan blade spins hits 82F and stops getting hotter. Flame at the tankless comes on but with no vigor. Could maybe light a cigarette, but definitely not vigorous enough to heat water. Takes 60 sec to flow 1 gallon on pump. There is a slight pulse in the pump, but that doesn't explain it being the same at hookups. Anyone?????
