Re: Seeking help evaluating hydronic heating advice and options
Your house was never steam. The large black painted steel pipes are for 1930 gravity circulated hot water.
he said ... You have an old refitted steam system with these huge cast iron pipes

Re: Repairing Mitsubishi Mini-Split Inverter Board
Usually homeowner's insurance covers damaged done by lighting strikes.
If so your best case would be that the compressor is shorted or open and also the PCB is toast.
Any HVAC person can check the compressor. Most of these people would condemn the entire system if compressor is burned.
Warranty at best would give you parts only. PCB is easy fix. Compressor replacement not advised, IMO.

Re: Caleffi 280 Thermostatic Mixing Valve
@OldawgBryant - good catch on the diagram. I corrected my earlier post.
Now I know that you understand it ;-)
The red thing in the photo is the B&G IAS (Inline Air Separator). It's piped to a compression tank above, and the fill valve connects underneath (not yet connected).
Below is the photo I sent to @OldawgBryant in an IM,

Re: Replacement for Beckett AFG nozzle assembly
Found it. Search on Lennox here:
https://www.beckettcorp.com/support/burner-settings/
The AFG air tube assembly ending in MB used on the COWB series is the AFG50MB. You need the nozzle line for this assembly. I don't see it on the site but one could call Beckett to get the part# that would then be ordered thru a supplier.

Re: Replacement for Beckett AFG nozzle assembly
Order this part https://www.supplyhouse.com/Beckett-AFG50MBAS-Air-Tube-for-Beckett-Burner
and this part also https://www.supplyhouse.com/Beckett-5394-8-Nozzle-Line
If we did not have the boiler model number Lennox COWB-3, we would need the tube length and the L1 style head info to get you something that would work.
The air tube length is the yellow line dimension. It would show up in the DEPTH column on this spec sheet above. With the part number AFG50MB you can get the correct size tube combination and just use the assembly part and scrap or save the tube for something else.

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.
