My wife just called me, and said that the house was down to about 58 or so. The temp gauge on the oil boiler (that my water has to flow through to get to the house) was down at 80. The tank temp was up over 150. So there is no way that it should be this cold. My guess is that it must be air trapped somewhere in the piping run between my tanks and the oil boiler, but I welcome anyone elses suggestions.....
The piping dips slightly, and then has an uphill slope before it runs to the oil boiler. There is a zone valve, a three-way diverting valve, and the circulator in the mix too. I have an isolator/purge flange on the circ, so thats where I bled it this morning. I got some air, but then a lot of water.
Unless I have my diverting valve installed backwards.... Oh would that suck.

I of course am thinking about my heat not working right instead of working like I should be today, and Im almost positive it means that my thermic valve is installed backwards. Its an LK 821, and they can be installed any which way, and its probably not uncommon for them to be incorrect, since the direction plate pops of and lets
The cold water from the house is hitting my valve, and instead of hitting storage, is pumped back around the loop into the oil boiler. It worked for me last night because the temps in the first floor loop of my house were fairly warm, so it kept the flow open from storage. Now to figure out how big of a deal it will be to flip that thermostat back around.....

Just a guess.

I havent.
And the reason I didnt is that the boiler seems to heat the tanks just fine, but the issue is when I try to move from the tanks to the house. It works when the house first calls for heat, but then as the water in the OB cools, it seems as if I lose flow. This morning when I checked it, the top of my tanks were hot, the boiler was out, but the pipes near my storage circ were cold. I purged the line, thinking it was air.
Ill check the thermostat and see how that goes. If not, Ill be back!
mikefrommaine said:I followed the PT1 diagram but I don't have the storage hooked up yet. So not sure if the bypass valve would have the same effect. But when I had the valve open too much I found that the hot water was circulating through the wood boiler but I didn't have enough heat going to the distribution system. I went through the same thoughts as you -- air, installed backwards etc. Once I closed the valve to 25% I found the system much more responsive -- and I was able to get enough hot water to the zones.
The system also seems to work better when I have the woodboiler circulator set to a lower speed, again I think when the speed is to high it pulls too much hot water out of the supply and through the bypass loop.
Good luck
Just watched a video of your brand boiler. Looks very easy to clean. Nice set-up.

Btw Scott(Clarkbug)...nice work on the boiler..looking good. Congrats.
