General Outdoor Furnace Discussion / Re: Problem with wood boiler water PSI being too high
« on: November 27, 2011, 01:00:19 AM »
thanks to everyone for all the helpful advice.
1) Relief valve and pressure regulator have both been changed 2 days ago
2) Expansion tank has no bladder, just the tank, no air vents on the tank, tank has been drained
3) Pressure does not go up and down with temp, seems to stay at 32- 35 psi regardless of temp (as long as temp is above 120 degrees
4) Will try opening relief valve and taking some water out of the system (since I may have too much water in the system, as one poster indicated had happened with his system)
5) All control valves, etc were serviced by technician about a month ago and I was told everything was fine. This was before I fired it up for the season.
Again, thank you all for your help, if opening relief valve does not work to correct problem then I will have a tech come in and diagnose the problem

General Outdoor Furnace Discussion / Problem with wood boiler water PSI being too high
« on: November 26, 2011, 08:07:12 PM »
I have an indoor wood fired boiler (New Yorker) with an expansion tank, 35 psi pressure relief valve and an automatic water regulator set at 12 - 15 psi. The system is a closed hot water system with finned baseboard rads/
My problem is that the water pressure is running at 32-35 psi constantly, causing the pressure relief valve to blow off, but no water is being added to the boiler since the pressure is so high. I have been told this is caused by air in the system somewhere. I don't know of any way to get rid of the air except by draining the entire system and refilling system. Due to the cold weather, this is not really an option presently.
If anyone can offer any suggestions \ advice it would be greatly appreciated, thanks.
