No heat in upper level
Hi I am new to this. My question is about heating. We have a forced hot water boiler that uses oil, we are not getting any heat upstairs. I have bled all the lines, water comes out of all the first floor lines, only air comes out of the lines upstairs. I can leave the lines upstairs open and water never comes out. We have an expansion tank and a fill-tron flow valve(?). A neighbor suggested adding water to the system? Does this sound right, and if it does how do I do this? I can take picutures if this will help. The upstairs has two bedrooms each with one baseboard. thanks

If the system is low on water, you need to open the fill valve to get the air out of the system. Most systems need very little if any top off water however. Is the upstairs on it's own zone?

You need to make sure the water feeder is working an dhtat you have pressure on the boiler gauge. The minimum water pressure should be @12 psi cold. You may find the feeder is bad.

water feeder
Thanks for the help, what is the water feeder and the gauge is at 12 psi when the boiler is idle.

How do I open the fill valve?

It doesnt look like the upstairs is its own zone but i cant find where the pips go up

Try and find the cold water line coming to the boiler, the feeder would normally be red or green depending on the brand. If you can raise the pressure to @20 psi before you open a bleeder on the second floor, it will bleed the air out easier.

I found the cold water line coming into the boiler, before it reaches the boiler it branches off and a line goes to the expansion tank. The psi is @ about 9 now even when the heat is on. Now there is a spicket on the cold water line just before it goes into the boiler below the red feeder valve if I turn it water comes out. I dont know what else to tell you. I will take pics and upload them later today. Thanks

How many thermostats do you have in the house?

stonegirl 12-16-2007 01:58 PM

We have one programable thermostat on the first floor

That would indicate that this is a one zone system.

Are any of the pipes that supply heat to the upstairs located on an outside wall?

If so, they may have frozen and will need time to thaw.

Has it been cold in your area?

What is the thermostat set at for the night time? or last night? (50, 60, 70... degress)

I found the pipe that goes to the upstairs heat, it is on the inside and goes through the wall. I dont think that it is frozen because air comes out when I bleed them.

The fill valve should have a small lever/handle that can be moved to manually allow more water into the system.

It is about 15 degrees out side and sleeting out right now. At night we keep the heat at 60. But because of this problem I purchased two small heaters for the girls rooms. There has been a few times that the kids closed their doors with little heaters off and the temp in the room drops to about 45.

Like a hose faucet, because there are four of those
