Indoor boiler question
« on: October 05, 2014, 07:39:40 AM »
I know some of you are experts on this......  My indoor boiler which is heated via my p&m 3444 is giving me problems.  First issue is my pressure gauge is reading 39 psi at 180 degrees.  I think from what I have read that is to high?? Also The only way I can get it to pump water to my upstairs zones is to have my pump on level 3 (high). 

Any thoughts?

The 2 things I can think slim.

I have a blockage or partial blockage somewhere in my baseboard heat.  Or I need to replace the airscoop, valve and expansion tank???  But those are just guesses.

First of all 12 valve is that the pressure relief valve should have popped long before that pressure, why did it not? is it functioning?

I don't know????  That is why I am here?  It is an old boiler,  But I am just using it for the pump and the thermostat that are built into it.

T&P gauges should be replaced often, the reading is more likely wrong. It's more likely the gauge is wrong than PRV being stuck. Both should be replaced every 5 yrs or sooner if they fail a test.
By the way was that pressure reading while the pump was on high, or is the gauge close to the pump? There are a lot of variables as to why you have no circulation upstairs. The pump speed should ONLY, control GPM. Not whether it actually flows at all. If their are no checks or zone valves stuck there should be gravity flow atleast, unless there is a heat trap.

Sprinter I sent you a PM.  The pressure gauge I am looking at is built right into the boiler.

I doubt the guage is built in, it's probably a threaded guage in a sensor well.

I could easily be wrong though

Was a plate exchanger used to separate the two boilers if so you could cut in a tee with a new well for a new gauge so you don't have to mess with your old boiler  also sounds like trapped air possibility try a good purging on the lines crack the flange on the circulator to see if it is air bound just some more info
