In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
I have a house built in 1896 that originally used coal as the heat source . At some point, they switched it to oil. system never seemed to work well (short cycling, uneven heat, etc). There is , I believe a return vent (see photo) , at the heater but with all the mains running in the basement, there are no vents on them . Should they have them and if so, could this be causing the problems?
