Started putting away some of the “garage tools” that were used in the basement for the new boiler install. Not all of them as I still have to disassemble the old boiler to take it out in pieces, and those pieces will occupy the garage until I figure out the salvage options. The old Larrs boiler has a stainless heat exchanger that weighs ~100#. Might be worth a trip to the scrap yard once I pull together all the copper and brass scrap I’ve accumulated.
The boiler install went well, but a few snags slowed it down for a couple days. I was planning on retaining the fancy-schmancy zone controller, but as soon as I powered it up, all the leds lit up like a Christmas tree, it failed to go through it’s start-up routine and no amount of re-booting changed that. WTF, you would think that it would work for 21 years, but I think it had a suicide pact with the boiler of the same age.
New Tekmar control and thermostats arrived and everything is working together perfectly. More than I wanted to spend, but this one controls the boiler modulation as well as managing zone control. I did have to call tech support as there was an error code for an equipment address that didn’t exist (I.e. - each thermostat or connected device is automatically assigned an address). Clearing the fault code was super simple, but it was not covered explicitly in the manual.
The boiler itself is just a beautiful piece of equipment. I could go on for hours, but I don’t want to bore everyone. I tend to geek out on hydronic systems, so unless anyone is interested, I won’t bring it up again unless I post a few photos, but no leaks!
Yard work to do and the Sienna has to be investigated as it has developed a new (bad) noise.
