Holohan Seminar (long ago)

Was looking though one of my old books on my shelf in my office and came across this from January of 1994.

Re: Holohan Seminar (long ago)

That was probably the year I met him and Erin at the Davis and Warshow trade show.
My father gave me the day off for any classes I wanted to attend back then and so I took full advantage.

Re: Zone 2 Upstairs Thermostat placement.

If you don’t want to put the actual control in that particular room, then get a thermostat with the option to use a remote sensor.

Put the sensor in the cold room and keep the thermostat in the master bedroom

Re: How is air getting in my system?

I am guessing that your diagram is a basement pipe layout since the radiators for the second floor are at the bottom, the middle, and the top of the diagram and at the same plane as the first floor radiators in some cases. So based on that. I doctored your drawing to make it clear that the second floor rads are actually higher than the first floor and basement radiators. The lines on the angle are actually vertical pipes.

Can you pinpoint what radiator is getting all the air?

To understand how air from the closed steel expansion tank can get into the radiators you may want to look at these recent posts

Re: AC BTU size for ice bath.

Forget the window ac. You need a medium temperature chiller. Everything for AC is a high temp.

The chiller will need glycol and your chiller evap temp would need to be 28 degrees minimum. Lower if you want a faster pull down. The window ac will never cut it. You need 3 tons at medium temp just for the water. If you tank is insulated the you will have to allow for the surrounding environment

Re: Wall Brackets for Wall Hung Cast iron radiator

I rarely come across old brackets that are practical for specific jobs so I like to use these homemade brackets. The gold one is 2-1/2” pipe which work on narrow radiators. I use 3” pipe for most radiators including one like yours. For the upper bracket I use threaded rod to fashion whatever tie is necessary to keep the radiator plumb. That varies depending on the radiator style. The silver radiator pictured is an installation with 3” pipe brackets in a commercial space.

I made the decision a long time ago that I'd rather replace the gauge glass than the boiler. So far though, in 8 years no issues.

Re: Tandem bowls?

They're ya go...dont be shy boys...NYC Public HSs up until the 1970s REQUIRED graduates to be able to swim well enough to survive. Oh yeah. And the boys all HAD to swim naked....hmmmm....Mamy also has rifle teams and ranges in the basement. It was normal to see boys carrying their 22 Cals in a gun case. Mad Dog 🐕
