Re: Thin Tube Steam/Hot water in Barre VT
You have to keep the water from getting there in the first place, you can't seal a rubble foundation, you can't seal a modern foundation. the lime mortar is soft so it moves with the stones, but it is just mostly cosmetic and does a little holding the stones together.
I would suspect the sewer long before I would suspect surface/ground water.

Re: Monoflo tees
two standard tees with a ball valve between give you more adjustability, and accomplish the same task

Re: Monoflo tees
I would use two MF tees for a kicker and add a purge set .. so you don't have the need for a constant rise …

Re: Monoflo tees
You could put a balancing valve on the main between the tees if you aren't getting enough heat from the emitter. Use long sweep 90's on the branch and use 45's and an offset wherever you can, 90's will be more restriction than the pipe itself.

Re: What would an “Expansion Tank Relay” been used for historically?
looks like a pressure switch that determines if the system is sufficiently filled from the weight of the water in the pipe to the expansion tank. If it opened a feed valve or shut down the burner is another question.

Re: Monoflo tees
It shouldn't make a difference. You will need a bleeder on the emitter because you won't be able to get the kind of flow you need to purge the emitter. That isn't specific to the tee orientation but because it is monoflo.

Re: Monoflo tees
A monoflo tee has a physical partition that divides the flow. that does a lot more to encourage flow in the branch than the pipe between tees. One or 2 depends on the resistance of the emitter and output and if it is above or below the main.

Re: Thin Tube Steam/Hot water in Barre VT
You have to get rid of the water, just sealing it up against the wall/floor is going to cause severe mold problems and cause the masonry to crumble.
Many boilers need to be on a noncombustible base so you can't put plastic under it without protecting it. Many boilers also need the bottom of the boiler sealed to draft properly. Check the manual.

Re: Thin Tube Steam/Hot water in Barre VT
Drain tile now is perforated plastic pipe that is run around the footing and to a sewer, sump pump, or open drain if grade allow that collects the water that comes from the surface or ground and collects near the foundation and directs it elsewhere. Originally it was short sections of clay pipe laid together with open joints that carried water away from the foundation.
The boiler needs to be below the emitters so the condensate can flow back in to it, you can't put it on the 1st floor(at least not without modifying the system so heavily that installing hot water wouldn't be more cost effective).
You can probably put the boiler on a pedestal in the basement but you need to be careful of some dimensions to the main and with the returns though the mains are usually the main concern with raising the water line. You can solve the main height issue with a drop header if it even is an issue.
