Thermostat question Steam oil boiler

Dhealy10 Member Posts: 1
Renting a older apartment and have an old boiler. We have a steam radiator in each room of the apartment and was just wondering if it is more efficient to keep the temperature at 70 degrees or at 60. I ask because a friend says im sitting in the cold for no reason as once the radiator gets up to 70 it takes the same amount of oil, once kicked on, to regulate the heat as it would if we were to keep it at 60. Any help is much appreciated!

    More fuel is used

    to heat a space to 70 than would be used to heat it to 60. If you set the thermostat back at night, anything over 3-4 degrees may not be saving any fuel because it takes a lot of fuel to get everything back up to temperature.

    Do all the rooms heat about the same? If they don't you may have an issue where the air vents are not doing their job. All radiators should heat at about the same time and rate. Make sure the location of the thermostat is not causing the system to shut down prematurely. Do you know what pressure the boiler is running at when making steam?

    Chase down and fix any drafts and consider using an electric space heater in one room to keep that room a little warmer - this heater should be turned on ONLY WHEN THE ROOM IS OCCUPIED AND NEVER WHEN YOU ARE SLEEPING
