Re: Prevent mold in mini-split heads
I've never seen a mini split that is not mold box after about two years. Even when it drains perfectly and the hole to the outside is sealed perfectly. Sizing doesn't seem to make any difference, the more it runs the more filthy it gets. The UV lights make the plastic brittle. The only thing you can do is deep clean them with the bib kit and power sprayer. Maybe this doesn't happen in less humid areas, but it's a real problem in the northeast. I wouldn't want one in my home. Although some manufacturers have models that are easier to clean than others.

If only they could (would) make equipment now that would last that long

usually they do radiant cooling in large buildings where they duct in ventilation air and that ventilation air is already dehumidified.

Re: Is internal circulator needed?
Major clue here. Baseboard hydronics and one tall radiator which, evidently, either can't be or hasn't been bled adequately.
I'm not at all sure that a bigger boiler is going to help you. You need to look at those baseboards and measure them up (the actual finned elements, not the overall length) and get the size of the radiator. Then figure out how much heat in BTUh those can put out. That is the maximum size of boiler that will be of any use.
Re: Is internal circulator needed?
It could be you need more heat emitters, not a larger boiler?
It sounds like you have a primary secondary piping, do the boiler would need a circulator
What brand snd model if boiler and what do you have for heat emitters radiant, baseboard or cast radiators?

Re: Can you help identify my B&G boiler pump? Possible replacement? Repair parts?
NOTHING made now will last 10 years never mind 75. Even if it is the same "identical " pump it is likely made in China or some of the parts are.
There is probably twice the copper in that old motor as a new motor. Take care of it. The volute and housing are probably fine. The motor can be rebuilt at a motor shop and new bearing assemblies are available, I think unless they changed th thing so a new one will not fit.
But you will need a truck to haul the money from your bank to Bell & Gosset. They give nothing away.

That's not a 100. Note the 4 bolt flanges, and flange to flange height difference.

Re: First time flushing hi-eff boiler-what do I need to know?
Looks like all you need is a flat-bladed screwdriver. And from that drop down screw, you have a Viessmann boiler.
Why do you want to flush your boiler? It should not be flushed unless there's air or a clog you want removed.
