drzbob wrote:Hi guys, our new K=6 Keystroker was fired up in Mid Jan and has had issues with pressure. Boiler is next to house, 65 ft of Thermopex to basement. House has new "pump wall" with 2 zones and Heat pex over 90% of house which is new. No leaks in the house at all and the pipeline is one piece so leakage would show up in the house. We used 30 gallons of Antifreeze and now the water is perfectly clear with no red color. System has a water feed, so pressure is now stable. So did the anti-freeze loose its color or is the boiler leaking inside and its going up the chimney? How can we tell and what can we do if its the Keystoker? Any idea's? thanks bob

We used a propylene glycol mix and its the mix they sell everyone with Outdoor wood boilers. I'm just concerned that we have a leak as the color is totally gone, and some of our pex lines have turned gray or brown. thanks again. bob

More than likely there was still some air in the system after the first manual filling and the system's performance was hinder due to all that trapped air. Sounds like he needs a high point vent.
