Re: Need some advice for a vintage Peerless radiator valve hookup
IMHO if the new radiator was on site for measurements and he was allowed to open up the floor to alter the pipe connections then he has no excuse for not making it right.
Re: Small baseboard zones
how long did you run the system?
It needs to get to a steady state condition, then observe the temperatures, the delta t.
Steady state is when the s&r temperature has stabilized, not going up or down
Delta t will constantly change as the building load changes.
You design a system around a certain delta, but in reality it may never run at that exact number. Nor does it need to if it heats adequately and doesn’t cause short cycling, etc.
Low mass emitters and light heat load conditions, steady state condition could happen in minutes. A design day may take much longer, of course.

Re: Pricing on refurbished cast iron radiators
It's a very small market in most areas. Here in the Detroit area I refer my customers to a powder coating company so they can go look at the samples and drop it off. I will usually just uninstall and reinstall the rads once they are done.
Re: I get all the weird ones...
"They need the door open for several reasons, they bring the material in with a loader, and then it gets placed with a 308 CAT excavator onto the conveyor. So they want the door open for the fresh air (i already told them bad idea) but also they run that loader in and out about a 100 times a day"
What a god awfull idea. Running a diesel engine inside a building.
Why don't they do things the normal way. An overhead trolley crane with a grapple. Staging area outside for unprocessed material. Crane moves material from outside in through a small opening right to the conveyor. Forklift inside for handling the bales.

air curtain. They are power hogs for the blowers, but they are oddly effective.
Re: New Century House with Two Pipe Steam - Questions
I honestly think these are just "pipe hangers," basically a sideways L drilled into the wall and then connected into something holding the pipe.
Re: Steam kettle trap
Might not be a bad idea to replace the bucket trap with an F&T. Bucket traps don't vent air that well, and if the air can't get out of the kettle, the steam can't get in.
Re: I get all the weird ones...
Since we're just throwing things out there. How about a 50 ft long entrance tunnel with doors at both ends. Only one door open at a time. Overhead IR heaters in the tunnel.

Frozen EVAP coil
4 ton Trane RTU. I replaced the compressor, TXV, drier few weeks ago. Performed pressure test and pulled good vacuum. Charged per the unit tag. Unit ran fine.
Yesterday service call- evap coil frozen. Thawed it overnight. It's cooling. R-410a.
110/262. My sub cooling is 12.5F. I have 20F across the EVAP coil. 54F discharge air into the space. Clean filter and good airflow. Only thing that concerns me is the low side pressure. My EVAP coil temp is 36F. I'm afraid it will freeze up again. But I'm reluctant to add gas as I charged the exact amount. I've checked the setpoints and schedule on the thermostat and it looks good.
Any idea?

5th pic from the top is the radiator leg off the floor like it looks like it is or is that an optical illusion?
Looks like the pipe is holding the radiator up in the air,
