furnace on, radiators only warm

in THE MAIN WALL
I have a gas furnace which supplies steam heat to most of the house, but hot water heat to finished attic and re-done kitchen. Hot water baseboards are heating up fine, but the radiators are only getting warm, some not at all, and having trouble heating up the rest of the house. Water level in furnace seems fine, the pressure gauge is at about 25 psi. Any thoughts on why the radiators are not really getting hot?

    Did you really mean 25 pounds...

    or 2.5?

    If 25, hopefully you're reading the water side of your system - not the steam side...

    BTW, you have a boiler, not a furnace. Although 50-year old literature also calls some boilers furnaces, we havmn't used that nomenclature since Dan was a kid.

    If the boiler's a little light on BTU's and the HWBB load is preventing the boiler from making much steam, that may be the result of extreme cold - or day/night 'stats demanding a lot come day temp start-up - all calling for day temp at the same time?

    If you could answer the following questions, we could offer better answers:

    1) BTU input of your boiler. Make and model wouldn't hurt

    2) S.F of floor area the home has

    3) Lots, normal or small amount of doors and glass

    4) R-what, in walls and ceiling/roof

    5) Town and state the house is in

    There are 2 pressure gauges, the other's needle is down around zero. Regarding your other questions, the boiler is a 3 year old Weill McClain (I am at work & do not have a model #)which replaced a similar 20+year old model. The house is about 2400sq ft, normal glass & doors, and we are on Long Island. The temperature yesterday was about 27F. We had the thermostat set to 68 all day and it only got to that level at 7pm (the house temp seemed to be about 65 most of the day). The boiler seemed to be on all day, but the radiators never got as hot as they did last winter. Any thoughts?

    Photos?

    can you post pictures of the boiler, its gauges, and its near piping?
