The oil company insists that the oil delivered is not an issue but may be forming bacteria if the room is too warm. Indeed the oil tank is co-located in the same 10 x 10 room. The first winter was full of complaints that the utility room was too hot. After an outside vent was installed on the Peerless, it was a little better. There are radiant tubes that run and terminate in this room, so they may be contributing to some of the heat. The unit is again starting to run loud.
I personally placed a call to the Peerless rep to schedule a call with the plumber and myelf. He says he's never heard of bacteria in oil..
A few questions come to mind:
1) Is there such a thing as bacteria forming in oil because the room is too warm ?
2) Will adding an "additive" to the oil help to prevent this bacteria ?
3) How often should an oil tank filter be changed; most likely more often if getting dirty quickly.
4) What might cause the Peerless to run loud, rumble to a stop ?
