Re: Radiant Heating for The Modern Home
Can not thank the person who posted this Kohler catalog enough. I had an old house in Sayville NY, circa 1940, that still heated with steam from an old Kohler furnace, looks like it was the model 'G'. Originally ran off of coal and was later converted to oil. Later I had it converted to gas but increased the size of the fire box to increase the amount of steam Ol' Betsy would produce. Extremely efficient even after 80 yrs of operation once the main line air bleeds were corrected to #2 Gortons etc. Absolutely loved that boiler. Thanks for the memories.

Re: Vitodens 100W Power Pump Module Failure
The fan and boiler are now operational!
The high voltage capacitors, optoisolators, gate drivers, offline switch and transistors were replaced in the fan.
I believe the problem originated with a shorted MOSFET in the fan that caused a power surge. The surge in turn damaged another component(s) on the fan board, blew the fuse on the control board and damaged 2 resistors on the power board.
I want to thank @GGross and especially @109A_5 for their assistance in the repair.

Re: Use Tekmar reset control with MZ boiler?
Surprisingly, we have 3, maybe 4 still going; parts are still available. They were all installed in 2000. If I had one, I’d be replacing it next summer.
High temperature systems lasted longer as the condensate from radiant systems eventually compromised the HX.
Don’t throw a lot of money for ODR on your new radiant. Maybe just a 3-way mixing valve. And you may have to tie it into an existing zone to keep the flow rate high enough to keep the boiler happy.
Re: mini splits working in conjunction with oil boiler
There ought to be a law... that control wiring shall always be attached neatly to terminal strips and clearly labelled. Although I will admit that it looks as though there might be some labels in that spaghetti bowl.
Really without being there with a test light and a meter, I wouldn't even know where to begin. Be easy enough if one were on site, though, and knew what one was doing and what the widgets were supposed to do.

How does my boiler get power?
I recently bought a house with an older steam boiler. I’ve read we’ve got steam and the lost art of steam heating to understand my system and make it more efficient.
One thing I’m not clear on is how does my boiler power the electronics like the pilot for the burners and pressuretrol? I ask as I don’t see any 120v wires anywhere.
The only two wires I see run to the thermostat and the gas shut off switch on the basement steps.
Also I don’t see any emergency switch on the boiler. Should I have one? Or is that the same as the gas shut off found on the steps?

Disclamer: I do not really sell that device. You can get the necessary components at your local auto parts store.

Re: Big box copper pipe vs plumbing supply copper pipe
I don't even know what brand they carry anymore, but I get all my copper from the big box. I had plenty of pinholes and other issues with Mueller and Cerro from the wholesale house at nearly double the price of the big box, so I'm content with whatever the big box has on the shelf now. I don't go through a ton of pipe, maybe 1500ft per year, but have not had any trouble since switching over. Same with PVC pipe- it doesn't make sense to buy from the wholesaler anymore due to cost.

Re: Large, Successful NYC Union plumbing Shop needs quality help
Just wanted to add...I've known the Owner, Vinny coming up on 40 years. We went through the plumbing Apprenticeship program in the mid 1980s. I also worked for him as a Journeyman Plumber, Heating installer, and Foreman on some smaller projects. The company has quite a few 25, 30 and 35 year employees. They have some of the Top Foreman in the industry and many very good plumbers to work alongside of & learn from/share.
They are looking to expand their service, install, renovate and repair department. This is a great opportunity for entry level to supervisor levels of experience. Being a Union Plumber off and on for close to 40 years, I am grateful I had the opportunity to get in the Local and what is has given me.
I am also grateful that I had the opportunity to work for such a good shop. Good luck! Mad Dog 🐕
