Set-up:
I have an over 100 year old house with radiant heat. The radiators were replaced many years ago with base board heat. It has three different zones with three individual pumps.
I have two furnaces. The first being a natural gas furnace and the second being a "Jack Line" wood furnace. They are plumbed together and can be ran individually or together by opening or closing valves.
There is a expansion tank as well as a line plumbed in to add water.
Problem:
Both furnaces will continue to build water pressure. The gas furnace will max out around 80 lbs of pressure! This will actually do nothing to the mechanics of the gas furnace and it will continue to run. I will occasionally release pressure to the preferred 15 lbs, but it will rise up again eventually.
The Wood furnace goes par for the same course, BUT it triggers the release valve dumping about 10 gallons of scalding hot water! Releasing the pressure on occasion comes to the same conclusion.
What I have done:
I have drained the expansion tank thinking that it had become water logged (no room for the additional pressure to go). Same conclusion.
I have systematically drained the pressure down to 15. Same conclusion.
I am sure that there is no air in the lines, because I have bleeded the lines several times (Usually right after it dumps the water and I have refilled).
Thoughts:
Is this a leaking valve (water supply line) that is continually adding water to the supply? If so, why does draining the "excess" water out of the line come to the same conclusion? Why doesn't the gas furnace pop the valve?
Is there a (hope the hell not) break in the water jacket on the wood furnace? Although, it does hold its pressure when not in use, in fact the whole system holds pressure when not in use.
There are no indoor wood furnace service people in my area, or surrounding area. As soon as you say "indoor, radiant, heat, and wood" in the same sentence they are done talking to you. The manufacturer (the Jack Line) was bought out. This unit was made in Warrens, WI.
Frustrating!!!:
The frequency of dumping water varies greatly. Most of the time it will go 2 weeks or better, but on occasion it will dump twice a day or sometimes three times in a two day period. Going through the routine of refilling and bleeding the system is extremely tedious!!!
Any help or thoughts would be truly appreciated! This problem has me at my wits end.
I'm not in the position unfortunately to replace this system, and being in town excludes an OWD.
Thank you for reading this.
