I think I caught George's bad luck

After a good productive day out in my shop yesterday, I went back out to load the wood boiler about 8:00 for the night. Had a massive blowout in the return line to the boiler. Not sure what caused it, but suspect it built up an air bubble that the piggy back circulator pumps, (one on wood boiler and one on oil boiler) couldn't push back down into the wood boiler and it air locked and then went to steam. There are also two PT valves, in the system, one on each boiler, neither opened.

Anyway, I just shut the auto feed pressure regulated supply to the system to stop more water from soaking my shop. Shut off the combustion air fan, and fire died down. Turned off all the distrubution system throughout the house and shop. The house only dropped to 67F this morning with everything shut down.
This morning I cut out the burst peice of Wirsbo heat pex and replaced it with a new one. (Glad that I have all my tools from when I was doing turn-key comercial buildings). Supplies and proper tools bailed me out on this dilema, as well as when my waterline from the well rotted out back a month ago..
There must have been a lot of pressure when it let loose, as it blew the drywall and fiberglass insulation that encased it on the beam,10ft across the shop. Some of the soggy insulation stuck on the wall above my overhead door.
The repair was quick and easy, but after I started reloading the system with water, and running all the zone circulators it took the rest of the morning to bleed off all the entrapped air. I have two manual air bleedoffs out in the shop and a auto air elininator down in the cellar on the oil boiler.
Refired the wood boiler after lunch and all is well, and saved a little wood. Also gave the bottom end of the boiler a good complete cleaning.

Loren, I always loved to hear water running when I got up in the morning. Our barn cleaner was fairly flat and when I went to the barn and heard water running into the spreader yeeahh. We have the same Wirsbo tool but have switched over to crimped ends for pex pipe.

I don't care for the crimpers. To tough to get them into some places. With the expander all you have to do is get the pex up on the fitting before it shrinks back.

Loren,
It's bad enough that woman blame men for all their problems. Now you are saying you caught my bad luck. All I got to say to you is MERRY CHRISTMAS AND HAPPY NEW YEAR.

Do you have a steam boiler or heated water boiler? In the 60's dad had a dairy and a milk processing plant. We used a steam boiler to pasteurize milk and heat the plant. Once a year we had to shut it off, take it apart for a state inspector to look at it. Boiler was set up for coal or wood. Wood in the day, coal in winter at night.

BTW, I think my bad luck with dishwasher may be related to Kitchenaid. Been researching dishwashers and my problem isn't unique. Many people post same problems. MarkB even posted a link to a class action lawsuit. I'm too late. I bought my last whirlpool, kitchenaid, amana, maytag products. All the same company. Even had bad luck with whirlpool washing machine.

I found out my kitchenaid blew the thermofuse, like the coffee pot. Both on the same day. One in the morning and the other in the evening. What are the chances of that happening? Dishwasher may be used for target practice. Bunn is working easy fix.

I think you are on to something Loren , George's post most probably has an imp inside it that leaps through the '' interweb '' portal and infects anything it can .
Shortly after reading about the various woes concerning the dishwasher, three light bulbs in our home blew out ,one after the other at hour intervals . No surge , just an imp or maybe two wreaking havoc :lol:

George, it is a hot water boiler. It is air tight and relies on forced combustion air. The aquastat is set at 180F and it shuts down the combustion fan. I checked that after refireing the boiler and it is working properly.
I guess I need to be a bit more dilligent on bleeding air off.

An old plumber told my Dad that bleeders are cheap in the long run. I was about 8 when I overheard that remark. Looks like nothing has changed! Glad it didn't do more damage.

one thing about it, loren, it wasn't 20 below and howling wind last night. glad it all worked out.

Bill, we also have an air tight fireplace which can heat the house in a crunch, and a Harman wood pellet stove in the cellar.

I've got the Wirsbro type too, and it's worked great for me - I'm surprised I don't see more of them
