Re: New thermostatic radiator valve on old radiator fitting?
You have a point there, but do you want to have to access the room any time or should I say ALL the time. The point of the TRV is that it is automatic. So the labor to install a manual valve or a TRV is identical for you. the only cost difference is the price of the valve and actuator. I like the idea of the remote actuator with the 6 foot capillary tube where you have confined space for the valve to be installed.
Re: Multiple temperatures on single zone with single circulator pump?
I think you will have problems balancing the system. I would use two pumps 1 for the radiant and 1 for the base board.
Re: Micron rise with respect to valve core removal tool
agreed but when breaking the vacuum use the refrigerant for the system.

Re: Preferred gauge glass cutter
Thia is the way it works for me. Bring a spare glass and you won't need it the first cut will be good. Don' t bring a spare and the first one will shatter.
Re: Purging air
As Bob has said that silver automatic air vent MUST BE removed. I am sorry I missed that at first.
The water cushion in the steel compression tank is gone and the excess water in the steel compression tank must be drained out of it to allow it to work properly and create the point of no pressure change.
It's better to drain the boiler and then crack the drain o tank valve in the steel compression tank to allow it to be filled with water to the right level. When there is nothing but water coming out of the drain-o-tank valve you need to shut it off and shut the water fill valve off.
Afte that you can restart the boiler.

Re: Questions about a steam system
So, water is only half way up the gauge glass, but the system was heating?
I'd think it's pretty clear it's not a hot water system.

Re: Need help with Radiant How to go laying panels over existing floor
viega and Uponor have a thin over the top board, it uses 5/16” tube you would need to fasten them to the concrete somehow and floor over it.
35 btu/ sq ft is kinda high for radiant floors, you will need to run a high surface temperature
Radiant walls and ceilings are sometimes easier to retro fit
Panel radiators are another option

Re: Questions about a steam system
Thats not a condensate pump. Can't tell if that pump is hooked up or not.
Steam for sure maybe with a HW zone off it.
Re: Questions about a steam system
That pump and those air vents make it a hot water system. Reinstate 15psi pressure.
