We recently moved in to a 1934 home with steam radiators.
Our upstairs bedrooms are cold compared to the first floor. A room adjacent to our kitchen is generally warmer than the rest of the house.
Can I adjust the radiators to try and correct this imbalance? It is possible the prior owners were ok with the bedrooms being cool because they were empty nesters. We are home all day due to covid and would like the rooms to be the same temperature.
I have attached a picture of a standard radiator in our house. Most of them had Hoffman adjustable valves. On the first floor the valves are set to 2 or 3 and upstairs they are 6/open.
I am confused if 6 translates to "hotter" than 2, if it's an inverse relationship or direct relationship.
I don't want to start fiddling if it will upset the apple Kart. Would anybody know if I should open the valves on the first floor and close them on the 2nd floor? I am assuming that opening or closing the input valve is wrong to moderate the heat and that the proper adjustment is through the air valve.
Any thoughts would be appreciated.
