kill overheat with wood furnace
I recently try to repare and modificate an heating floor system with a oil and a wood furnace. Bolt on the same system. I made a parallel connection with the boilers and I put only one circulator on the return pipe. I didn't use a pump on each boiler because I was thinking that if the water pass constenly inside the oil furnace can help to kill the overheat when the wood groove working. The boilers zone had 1-1/4 cup pipe with a buffer tank set at 160F and then, I put an injection pump who feed the heating floor zone with an aquastat localisated on that zone. The heating floor zone is setting at 110F because it's all slab with ceramics. The system also have an indirect water heater and a big garage (36x40). I put a 1-1/4 pipe to connect the injection pump between the boiler and the heating zone because I was not sure how to do it. What can I do if to adjust easly and fastly if I oversive the injection pipe????? What should be the cheaply and easier way to kill the overheat if I still have on the boiler zone??????
