Richardson Vapor System

Petheat

Good morning all. I have a plumber friend who has run across a Richardson 2 pipe vapor system. He's adding a couple of radiators to an addition. Can he pipe those as a 1 pipe with an air vent? Will that affect the rest of the system?

Thanks guys!

Yes, he can, though it would be better if he could run a small diameter (say quarter inch) flexible cooper line back to the dry return from where the air vent normally would be tapped in. That line might even need an orifice to control heating rate on those radiators, since they can't be contrlled with the inlet valve.

Steamhead

I wouldn't. That system was designed to work in a certain way, at very low pressures, and if he tries to scab a couple 1-pipe radiators onto it, they might not work well or he might throw it out of balance.

The proper procedure is to hook the new ones up the same way the originals were. Since Richardson return fittings are no longer made, use standard radiator traps on the returns.

I was going to add to make sure that that small diameter vent line can drain — but @Steamhead 's advice is much better than mine!

Or run them as hot water as a separate zone off of the hot water in the boiler.

Is it possible to run a counterflow directly from the boiler?

Steamhead is right.

Thank you all. I've revisited the project sight today. I'll attached a few pics soon and add more to my previous post, please stand by!

I'm 65 and have been around steam since I was 20 but I am humbled by our predecessors and I'm thankful for all your expertise, we are truly always learning!

I’m 73 and still learning. Thanks.

Ok..But my first Memory of You was the B & G pamphlets...Counterpoint?  Right? Wasn't that mid 80s? Some supply houses had them out on the Counter.  I caught the Dan Holohan Tidal Wave...at the Perfect Crest...still On the Surf Board , enjoying the scenery and looking ahead.  Mad Dog 🐕

Thanks, Matt. Yes, mid-80s.

I once did an oil to gas conversion on a 1910 Pancake-Snowman Boiler connected to a Boynton and Richardson Vapor System.  I had never come across THAT particular two-pipe system so I was hoping everything would go well.  I remember calling Dan for advice on the number listed on his books.  He picked right up.  I had been to his seminars and had all his latest books but the internet and Wall were not quite around yet.."Build a nice generous header, keep the pressure below a pound with a Vaporstat and vent it well!" I did as he said, and it went flawlessly.  That boiler made it on to The Burnham Calender that year.  I didn't know about Gorton #2s at the time but about a year later, I replaced the ordinary ones with the Gortons.  I still maintain this system and its over 20 years and plugging away.  A few months ago on a Consult in The historic Long Island 🏝 Gold Coast town of Seacliff, I came across a Richardson "Expeller."  It was still working!  I like stuff that was built to last 150yrs....So..Pet...let's see some pics buddy.....Very simple to add on a supply & Return.   Mad Dog

21 years.....Geez...I wanna go atleast another 20 doing this..I'm going to be the Old, Half-crippled,  curmudgeon plumber that loves to tell War stories, impart sage advice to the "Yutes." (Fred Gwynne - My cousin vinny) and actually will crawl in to a crawl space to inspect the work.  I relish that role!!  It's not work when you love what you do!  Have a great day you'll Palm Sundee...gotta hit 3 different cemeteries today from Queens to Farmingdale to lay PALM crosses on Fambly plots..God Bless  .Mad Dog

Returning to original topic and my question. Are you guys comfortable with breaking into a vapor system? (besides in the boiler room)
That is why I asked about independent pipes to additional radiators?

Mad Dog_2

Yes!  I believe I said its easy!  Is there ACM on the piping?  Mad Dog

"LETS SEE SOME PICS...VERY SIMPLE TO ADD ON!.  just waiting on you.  Are pipes accessible? Mad Dog

So..... if it was still working why was it removed and does the system work more efficiently without the vacuum or was there some other modifications ? Thanks 

Mad Dog_2

It was already removed and lying on the boiler.  They replaced with a  Cheapo main vent, but it was doing ok.  The big problem was an undersized boiler. Mad Dog
