Hello - hopefully I've posted this in the right section...
I have an 8-year old house with radiant heat system in the slab. The system has worked fine for the first 7 winters, but this winter I have new problems.
The system had been on for several weeks, then started making gurgling noises one night. When I went out to the garage to see what was going on, I could see air bubbles passing through the tubes. I shut the system down immediately.
My first thought is that I have a leak somewhere, but we've seen no evidence of that.
The system uses a residential hot water heater to heat the water, has a Honeywell Sparco PV100 air remover valve, and an Amtrol expansion tank.
There is no pressure guage on the system, so I can't tell how much (if any) pressure is left in the system. When the contractor filled the system originally, he simply attached a hose to the spigot on the bottom of the hot water heater and let the public water pressure fill the system. He then ran the pump, circulating the water and purging the air from each zone. when he was done, he disconnected the hose and the system has been at that pressure ever since.
I've posted some pics below. Note that there is extra copper piping in some of these pictures because the regular hot water heater in right next to the hydronic heating system.
