New to the site,
I have an issue with my steam system, a little background info, I just had a new oil fired furnace installed in the summer of 2015, its a one pipe system. its a two family house. I have 4 radiators on the first floor and 6 on the second floor. I took over this house after my grandfather passed away this year. I took care of him and he lived on the first floor and I live on the second floor. The first winter the furnace seemed to work fine, I have an adjustable thermostat put in and had it set to 68 in the mornings and 65 during the day. the second floor has always been a little warmer but nothing that felt unreasonable. The thermostat is located on the first floor. I started my furnace the first week of November and its been about 10 degrees different from the first floor to the second floor with the thermostat set at 55 degrees. Then about two and a half weeks ago it went to 15-20 degrees warmer on the second floor than the first floor. So now I have the thermostat set to 52 degrees and the second floor is 66-68. FYI no one is living on the first floor.
I have installed vent-rite adjustable vents on all the radiators. I recently took them all off and cleaned them with warm vinegar and I blew in all of them and they seem to be working. I have all of them set on venting the most air. I also replaced the batteries in the thermostat. I also put a table top thermostat in the same room as the wall mounted one just to make sure it was good and both were within 1 degree of each other. However I also just purchased a LUX touchscreen thermostat to replace the other one just in case.
from what I can see i do not have any main vents on the main and I take it there never was any. I have had the furnace skimmed several times and I have them coming again this Thursday to do it again. I have talked to my oil company and they seem to think the problem is as easy as just adjusting all the radiator valves in the second floor down to match the heat in the first floor.
I guess im scratching my head because this has never been an issue and even last winter with the new furnace it wasnt an issue. the first floor was always 65-68 degrees but the second floor was never 85-90. so why all of a sudden an imbalance? it also seems to be going through a lot of fuel for a temperature set at 52 degrees. full tank starting in November and just had to order another 150 gallons.
any suggestions on what I can do? or where to look?
