Re: Does any one know who manufacture's the mini-splits sold as Mountman?
Refrigerant for extended line sets are weighed in in oz. according to line set length. If the manual doesn't provide that data sheet, I wouldn’t even consider purchasing the product. Why Mountman? Because its on Amazon? Because its cheap? Because of their excellent tech support? Because parts availability is plentiful and handling warranty items is not a PITA at all? Because the customer already has a Mountman portable swamp cooler and its wicked awesome? Penny wise, pound foolish comes to mind with this.
Maybe Mountman is great. I don’t know. I do know if I want to sign up for their email, I need to know Chinese. I can't even tell if its Mandarin or Cantonese.
You've been an HVAC pro 54 years. I'm assuming the customer has been an HVAC pro for zero years. Can't you talk sense to them? It starts with Mitsubishi, Daikin, Fujitsu, Bosch, and goes down from there. And if their second choice is MR. COOL, run. Run as fast as you can.

Re: Trane ac air handler
Ed,
I assume I can replace it then with the RLY02807? Looks like that has the time delay board built in. I think that is the way to go, looks like they’re under $100. I’ll just have to figure out the wiring.

Re: boiler replacment opinion on the West Coast
I have the same setup as you are suggesting except my Viessmann (V.) is a 100 series. No need for the 200 unless you have lots of peripheral equipment (mixing valves, solar, etc.).
I service many V. boilers in the City, East Bay, Marin and South Bay and stock the most common replacement parts as, unfortunately, parts are not available locally. I urge my customers to stock these parts there, with the boiler in case I run out or if they call in someone else for repairs.
The 120 gallon indirect sounds too big for you. I’d go with the 80 gallon. V. has the best stainless indirects. None of the ones I’ve installed over the last 40 years have failed.
Lochinvar also makes a great boiler and they, along with V. have good technical support.
Edit:
"In looking back and with current research it seems my installer did not account for the value of stored thermal mass even though I have a decent size mechanical room."
Stored thermal mass? I don't understand.
"I’m also considering 2-3 solar thermal panels now or in the future."
Oh, I see. The solar add on is why you wanted the 200 Vitodens. I'd skip the solar thermal. Too expensive to maintain and repair. Solar electric is a better option.
Re: Boiler Header?
Depends on your craftsmanship and ability to source components. If you can find the correct components and your design and craftsmanship are up to what Caleffi or some others can do, yours and pre-made will be equal. Yours will probably be more expensive, quality for quality.
Re: boiler replacment opinion on the West Coast
Air to water heat pumps are common in that area, climate is a good match, incentives are available.
Corey Page posts a lot of HP conversation on his IG account, in that area

Re: Can you help identify my B&G boiler pump? Possible replacement? Repair parts?
"Point arrow towards wall" means do not point to floor or ceiling. IMO
Horizontal shaft position only. Some may have been confused by "Horizontal" and "Vertical" wording.
I have a 1961 school with 2 pumps similar to this. Both original motors still working.

And cost much more than $36 to service. They are nothing but trouble.
Re: J-channel mounting block suitable for Prier C-134 series
Use a wooden block cut to the flange with whatever reveal you want and install j channel around it.
Re: 1933 Burnham Boiler - Questions and Potential Replacement
the actual input and out put will be set by how the oil burner is set up. coal boilers typically weren't fired at their full capacity for a number of reasons. it looks like that is a multi pass boiler so if all the baffles are in place and the oil conversion was done well the efficiency might not be terrible.
