Diagnosing Problems with Outdoor Wood Boiler (Central Boiler 5036)

When we bought the house there was Central Boiler CL5036 already installed by the previous owner. Since we fired it up this fall, there have been issues with the boiler. In these series of videos, I attempt to diagnose the problems. And it turns out there were multiple issues.

    I enjoyed watching your video I’ve been a central boiler dealer and installer for about 14 years and although it was somewhat comical to me I do know that it happens often

    Bro, did it ever occur to you that the outfit you had winterize your boiler put the pump on upside down…?
    Original owner used it to heat with, then you took ownership, had Miguel from eye ball heating and cooling screw your shit up.. Not the original owner…

      Thanks, but we didn’t have an outfit winterize the boiler. The previous owner had winterized it for us before we took possession of the house. Also, complete removal of the pump wasn’t necessary for draining, even if blowing the lines clear.

      As you may have seen, there are plenty of other issues related to his self-install of the system. But we have got it all worked out now. All is well.

      To help confirm this, the people I spoke with who sold the original owner the system knew he installed it all himself because they were related to him.

      Just recently going through some paperwork in the basement I found hidden under the furnace, he had notes for himself to leave the breaker turned on for the water heater. That defeats the purpose of using the wood boiler for hot water. So instead he was using propane to heat constantly even though he has a sidearm hookup for the water heater.

      He definitely burnt wood in his boiler, that’s for sure! But to what advantage…

    Did you ever get this figured out? I can see from the video he has it plumbed wrong on the water heater

      Well, we have not replumbed the furnace area or the way it’s setup. However, the issue with the boiler turned out that the previous owner had installed the circulator pump backwards. The pump was actually trying to pull water from the house and push it to the boiler. It is supposed to pull from the boiler and push towards the house. A lot of comments said that’s not possible, but the certified installer said it was highly possible. The installer also said that could very well be the reason why the previous owner went through so much wood and still had to use the propane.

      It’s ironic that I am replying to this now after finding what we found just last night after we had a serious vibration in the furnace unit and ductwork. Check out the video coming later this afternoon! I will title it “Yet another furnace problem. The saga continues…”
