Thanks for the video, Gordon! We're professional engineers and NYC plumbers, and installed several hundred of these over the course of a year or two. They looked good, well made by an American company with a good history. Two-fifths of them failed in a year. They stopped venting. We cut one open and found that the bellows had dismounted from the top and fell onto the aperture. So we called Heat-timer. We wrote to Heat-timer. Never a response. We were out thousands of dollars and had dozens of angry customers. A great idea - like a mini-steam-trap. But there's a design flaw. And the company, like its product, fails its customers.

I found a copy of the Audels oil burner guide a few years ago I remember some of the information thanks for sharing. I have a two pipe system and have a Hoffman 75 installed on the steam separator two pipes vertically hung with a cast iron contraption on top and the main vent on top of the device, I think the main vent was replaced about every three years or so. I’m never thought about using anything else but you have a good point that Hoffman 75 isn’t the best thing. I have about 600 square feet of radiation around the building and I’m thinking about adding some more radiator’s to some cold area’s. I’m going to get a thermal video camera attachment for my phone and start looking at the steam to find out where it works and where it goes wrong. There’s no shortage of work as a homeowner, but thanks to you it’s been very easy to understand how to troubleshoot the steam heating system. Not everything is the same in two pipe steam but there’s enough similarities to keep it interesting.

@davidlampe41532 жыл бұрын
I have two steam traps at the end of the mains I thought it was weird that they were uphill from the mains to the dry returns and I changed the nipples to make them downhill But I was corrected by an old timer who said that there was no steam left by the time the steam trap was reached the end only air so it wasn’t necessary to install longer nipples. I did remove two large radiator style steam vents from the top of the wet return pipes at the end of the mains they seemed out of place and not in keeping with the rest of the system. I can send you a link to a video I’m thinking about making since my skills at descriptions are inadequate.

Thank you very much for the kind words! It took me a bit too long to realize that if someone is putting a Varivalve on a radiator, it works because it's treating the symptom and not the underlying problem. In the meantime, the customer is having to put up with the notorious V.V. spitting and early failure rates. On the plus side, they add good weight to the scrap bucket! Thanks again & happy quiet steaming.

I used on a radiator on the end of a main that I couldn't get to heat. I had a Gorton No2 vent after the take off for that radiator and had all the other radiators working perfectly. I suspect that the boiler may be slightly undersized. That vent finally got that radiator to heat.

You bring up a good point about an undersized (or underfired) boiler causing otherwise properly vented radiators not to heat properly. "If you put a big vent on a radiator (and have proper main vents on the pipes), and it still doesn't heat properly, it ain't a venting problem"

I use one of these. It's on a W.W Carman's radiator from the 1880s. It's bigger than a small boiler, and most vents are too small to get even 1/4 of the air out of it during a cycle, even with main vents properly sized. The Varivalve does work for it, with the additional benefit of fitting properly under the top cover due to the short height. No spitting because the vent is about 3 feet or more up off the ground. I would never use one on anything smaller but for such a massive radiator it or the Gorton D are the only vents available beyond putting an elbow and small main vent on the radiator.
@gordonschweizer51547 ай бұрын
Thanks for your comments & observations! I think what the Dead Men used to do is drill & tap the larger radiators that were hard to heat in two places to install vents. The steam would reach one first & shut it down after a lot of the air was gone, and the other vent would continue to allow the air to be expelled, but at a slower rate to reduce the likelyhood of spitting & gurgling. This all supposes that there was also massive main venting, of course.
@theodorgiosan25706 ай бұрын
I have seen that in Audel's Oil Burner Guide. On this radiator because of its rarity I don't dare go anywhere near it with a drill. On something common like a thin tube or similar I would maybe try that, or a manifold that holds two vents. In this case, this seems to be the only radiator that works well with a Varivalve. It has the right combination of almost comically large size, super high vent location, and on the end of a very long steam main. Even with a Gorton D it doesn't heat up fully with the boiler running for hours. Wonder how it was supposed to work in the 1880s, when I can assume vents had nowhere near the venting rate they do today? I suppose with coal you could wait hours for the thing to heat up. It weighs around 350-400 pounds, maybe more, with wrought iron tubes, steel? inner tubes, and a cast iron base. Believe me moving the thing to repaint it was difficult, even on linoleum where it could slide. It had to be stripped and repainted right in the kitchen where it is, moving it somewhere else would have been nearly impossible.

I've heard that the Varivalve line suffered a really bad run recently and you must have been caught up in that. Hope you got your money back. As to your needing Gorton C to get your radiator hot, have you looked into improving your main steam venting? By venting your mains properly with large vents, the radiators can be vented with smaller vents. In general, smaller, slower radiator vents last longer due to not as much rust & stuff being sent through the vent orifice. Also, radiators tend to heat up with less spitting and sloshing in most cases (also a general case... you yourself might be just fine). It is easier to balance a system with good main venting as you can dial in the venting on the radiators when most of the air in the system is dealt with in the basement. Stay warm!

Great video! Watched a bunch of your others too, thanks! I have a Gorton # 1 on my main. It takes 2 to 4 minutes of releasing steam before it shuts off. Is that normal? It seems 10-30 seconds should be enough. 1 year old small (100k BTU) Weil-McClain. Could surge be affecting my Gorton? (I have always used Hercules boiler liquid). PSEG wants me to fill it to 3/4 (I think the lower the better as it's steam I want). It has to be refilled more often than my old peerless. BTW, I replaced the Gorton #1 with a new one and it is doing the same thing (may be from same lot as both were given to me by 1 year ago by PSEG). BTW, I have all (working) varivalves on my radiators which I will be replacing after this.
@gordonschweizer5154 Жыл бұрын
Thank You! As to your issue with the Gorton #1, it appears from reports by others that they are going through a rough patch as far as quality control is concerned, sad to say. But you might be having wet steam issues, as you suspect. 3/4 is too high. I would try to run your boiler water level at about mid gauge. I believe that is close to what the manufacturer calls out for. Check to make sure your pressure control is set to the lowest possible setting & the pigtail is clear. Is the near boiler piping correct? All the Hercules boiler liquid in the world will not overcome bad piping.

@@gordonschweizer5154 UPDATE: I installed both my Gorton #1's and both were letting out so much steam the water levels dropped like crazy and I'd have to refill. I went and bought a third and installed. This new one barely vents but at least I'm not losing water. Meanwhile, I returned the first two to Gorton and they quickly sent me two replacements in exchange. Will try one later today to see if I can get goldilocks "just right". Also, I got PSEG to give me a new Pressuretrol. I installed a 3 psi gauge next to it for a more accurate reading and it cuts off at 2 1/2 psi and then back on at 1 psi (settings are at the lowest at .5 with 1 differential). The old-brand-new one wouldn't cut off lower than about 4 psi. So much for getting it to run at 1 1/2 psi. Not happening so I'm going to have to live with this. The piping and the Hercules had nothing to do with all this. Thank you!

I am sorry to say I do not trust the longevity of the B/M vent over the average Gorton #2 vent for constant steam exposure cycles mainly due to the o ring seal.
