Re: Moving steam return in one pipe system…images in thread
If it is a return it has to be under where the steam condenses in the main and the emitters, the water can't flow up hill.

If you raise the pipe it will probably trap water and you will get water hammer. But we need pictures to tell for sure. Chances are if it could be raised the original installer would have done that
Re: What type of Vent on pipe near boiler in basement
@mattmich and @ethicalpaul , the other part of the equation is……. balance.
You want the steam to reach the ends of all the mains, not only quickly, but also at about the same time. Once you accomplish that, the steam is available at every tee where a radiator connects, and will rise to all the radiators at the same time. Balancing the heat in all the rooms is easy when you do it this way.
This is where "pipe math" comes in. Once we know how much air is in each main, we have our starting point for sizing vents. Occasionally we need to make changes from the original sizings, but having that starting point gets the job done faster.
Re: Turning off power to minisplits
Could be a crankcase heater to keep the compressor warm and keep the liquid refrigerant out of the compressor. No harm killing power but they used to recommend 24hour CCH warm up before starting. Probably doesn't need to be that long but it is what it is.
Re: another copper press fitting peeve: street female adapters
For commercial repairs I think the hot work permit process is driving service people to press options.

Re: Need Steam Specialist in Portland, Maine
Who installed it? Not that old. Piping doesn't look horrible from what I can see.
Someone here may know someone in your area. Portland is a large city there ought to be someone. Maybe check with some P & H supply houses to see if they know someone who knows steam. Steam Experts are dwindling. Maybe @New England SteamWorks
Re: Bad homeowner steam advise= $$$$$
The pressuretrol got a workout, sure, but it stops the burners
There is no way 90% of all the produced heat went up the flue
Anyway we can all be sad about the house going down but I don’t see the boiler being responsible. Sorry for the disruption
Re: Bad homeowner steam advise= $$$$$
i mean like 2 years of that 20k would have paid someone to put in appropriately sized emitters and fix up the boiler to bring the heating cost down to the coupe k that it should be.

Horse Barn Radiant Heat
Just got asked to bid a horse barn project using radiant heat. The customer was looking for some direction on if the stalls get radiant under them. My initial thought would be no because of bedding or stall mats would insulate the floor in that area. Plus ammonia issues in the stalls. I know the barns we have kept our horse at has compacted dirt floors in the stalls with bedding and no concrete. I am planing on the aisle way, wash stall, tack room, etc. Has anyone done a project similar to this?
Re: Horse Barn Radiant Heat
i think if yo heated the stalls you would only want the water to be something like room temp, if you heated it enough to provide heating you would turn it in to an incubator.
