Please Help No Heat In Upstairs Radiator Downstrairs Is Fine


My temporary fix has been to force water into the furnace and bring it to about 11psi. I then bleed the radiators until i get water. This works for a few weeks or so then I lose heat agian. It seems that i lose water and pressure. I have no leaks in the house. Its a small area 800 sqft to heat so its not a big system....any ideas or advice/help would be great!!!!


Thank You

How old is the expasnion tank?
The furnace should "fill" on its own.
Do you bleed the system?

I would say you need at least 12-15psi to make it to the second floor, do you have an autofill installed into the system?

The boiler should maintain 12-15psi as has already been stated. Your fill valve is probably broken. Manually raise it to 15psi and see if that helps.

The circulator pump has nothing to do with the pressure which we have already established is your problem. Go to your local plumbing supply and get yourself a new fill valve. I recommend against Home Depot, Lowes, or any other big box stores. They tend to go for the cheapest stuff they can get there hands on.

if the circulator pump isn't running you won't have any heat and the boiler would be satisfying itself on the limit due to the water not being circ'd.the pump should run when the stat calls motor should be warm to hot(depends on location around boiler)i am thinking you have a steam boiler not a hot water boiler...with loosing water and pressure but no leak?

Ok, hold everything for a minute.
I assumed this was hot water. If you have steam ignore the previous advice, you have a different problem.

Hot water boilers do loose water and pressure over time. I'm not sure exactly where it goes but if you shut off the supply to any boiler usually in a few weeks the system is going to be low. A new system can probably go a couple months but it will eventually get low.
