New Burner is taking forever to heat house
Its a rental house. The old burner was 30+ years old and the owner wanted to install a more energy efficient unit, which I was completely happy with as I pay the oil bill. I do know that the temperature is currently set at 150, but I have no idea how to dial it up to 180.
The thermostat was changed two weeks before the burner and was functioning properly.
I am guessing that the age of the old burner and the new one that they likely aren't firing at the same rate. last night it took 4 1/2 hours to get up to 70. The water is nice and hot coming out of the taps as well, but it doesn't seem to circulate through the pipes very long so maybe it is the pump.
Now showing my ignorance, is the pump part of the burner unit or is it completely separate? If separate is it possible that the old pump isn't compatible with the new burner? How would changing the burner suddenly make the pump not work?
