: Incest in a better, tighter, insulated door and insulate that cold room in the basement with an insulated wall. After you tighten up the basement, you will have better heat. Insulating the basement ceiling will help. These are the least expensive, longest-lasting money savers.

: I have no idea why you have the circulator come on at 160F, unless you make hot water with a tankless coil in the boiler. However, you can move the high limit up to 200F, so if the boiler has enough capacity it will give a little more heat upstairs. Steam boilers operate at 215F without melting.

I have the circulator set at 160 degrees, because it allows the water in the tank to get
heated hot enough before it moves to the radiators. If I set it higher it does not kick on
enough and the living room radiator will not get heat because of the way the pipes are setup. It sounds crazy but it is the last radiator to get heat no matter how I adjust the other radiators shut of valves. This radiator happens to be all most directly above the basement door to the outside. Should the circulator be set lower? When I do set it lower
the boiler has a hard time reaching 180 or anything over it seems when the circulator kicks on for a longer period. My boiler is at least 30 years old as much heat that goes into heating the water goes out the chimney. I could heat air with what is going out the chimney and heat the whole house. We are saving for a new one hopefully for next year.
