  • Winter Heat - Keep a jacket handy

    As we are all aware, the building is old and winter makes the space uncomfortably cool on some days. Please note however that the space will be experiencing abnormally cooler days than usual until further notice. We are currently running one boiler as opposed to two due to pressure issues and a bad gas valve and the other day we had the spring coupler on the main recirculator pump explode (Seriously. The tension springs chewed up the bearing housing pretty good) Please do not touch the thermostat as the system currently cannot deliver a lot of heat. Grant Fraser I left you a note in regards to the disconnected boiler. Nicholas Adams I have dismantled the pump and removed the remains of the coupling and left it on the office door. Replacements should still be available at IPH. I spent tonight cleaning, oiling and retesting the motor and it's still useable.

    Wow. Thanks for that. Now I know who the ghost is. I did already reconnect the second boiler. They run in parallel. I wondered why the heat was turned down and I put it back up. Thanks for looking after the motor. I wasn't going to be able to look at it until Wednesday.

      Sorry, I should of made more people aware about that change when I did it last week. We can run with one boiler for now and we've done so for most of the season so far (because of said sticking gas valve) but I don't trust the system enough to leave it running a high pressure from both boilers running until we can figure out why it's trying to run so high.

        The air pressure control tank was waterlogged. It's old enough in this building that it doesn't have a bladder so every few years the extra water needs to be drained out or else the system hydraulically overpressurizes. I've gone and done it now and that seems to of taken care of the pressure issue.

        there was also concerns the wiring or control relays were acting up again so I hung around and watched the thermostat call and then satisfy with no weirdness so electrically everything is working fine.

          It's 1AM and I've been in the basement for the last six hours repairing the boilers after the space was apparently without heat for at least a day. Looks like the boiler relay has burned out from cycling too much and sometimes turns on when tapped with a screwdriver. Also found the Blue pump motor thermostat overheated and burned up some of its BX wiring so it will need a new terminal block.
          All the old control wiring has been replaced and the old relays have been replaced with new modular relays in a cabinet. There's a few things I still need to go back and adjust but this will get the heat back on.

          It's been four months since that coupling failed and I asked you to go buy us another one. this isn't an optional component. the building NEEDS it running. I could be heading home now but because it's still not repaired I have to sit around for probably another hour to make sure the system comes back up properly.

          Edited: Came back in at noon and finished tidying up the rest of the work from last night. A new coupler has been ordered from J Walsh and hopefully I can install it on Monday. I have printed two copies of the new system documentation and left one in the office and the other in the relay panel with a schematic so that everyone required knows how the system works and how it's wired.

            Thank you so much for all your work on this, it is appreciated more than you know. The work you do in the background tends to blend in and not be noticed by most, but know that you are appreciated MIPS
