Main Vent for steam boiler
Could location of the main vent effect one of the radiators not coming on except when therm temp is turned up by 3 or more degrees? Rad doesn't work when trying to manitain same temp throught the day, only when it's turned up by 3 or more degrees.
The main vent it located very close to the boilder. Can another main vent be installed closer to this rad to help get heat to it?
