Roasting in the basement

Blackoakbob

When you set the stat at 64 is that the temp you want in the living area? If not then use a digital amp meter and check the red or r wire at the boiler as someone turns up the stat then set the slider in the stat at that reading and that should give you a more accurate operation.

Warm Basement

We have an old Weil McClain boiler that's about 65 years old. And while it's still running great, it puts out a ton of heat in the basement. (It's often at least 75* in the boiler/laundry room during the heating season.) Is this typical?

Sometimes, the boiler will run for 3-4 minutes and steam doesn't even get to the end of the mains before the t-stat shuts off the boiler. The boiler is in the room below where the t-stat is located. I often wonder if all that heat is making its way up through the floor and effecting the t-stat.

Any thoughts?

i am assuming it is steam

are all the pipes insulated? you will loose alot of heat with no insulation

Yes..

It's a steam system and all the pipes are instulated.

It has been my experience that an oversized boiler which short cycles will also overheat the basement. At least thats what mine does. Is your boiler sized correctly to the radiation? What is the anticipator setting on your thermostat?

Anticipator

The anticipator is set at .3 amps. I set the thermostat at 64* to achieve the desired heat for the house. Generally, the boiler does not short cycle. (Most cyles are about 7- 9 minutes long with about 18-20 minutes between.) But at times when I set the boiler back at night to 60*, the condition mentioned above will occur.

Not unusual...

... the basement of the apartment we're renting has two steam boilers. It's always warmer down there than most areas of the home. Some pipes are insulated, some not, but the boilers do lose a lot of heat via the jackets, flue pipes, etc.

The boiler room in the new house receives combustion air via the great outdoors and it's always warm even though I have been very busy trying to get all the pipes in there insulated. Besides fitting insulation around the flue (either B-vent or blankies), the next step will be to shut off the RFH for that room...

When you say 'at the boiler' do you mean where the red and white wires connect to the transformer or after the transformer at the gas valve?

Thanks.
