Re: DEAD WRONG

@STEAM DOCTOR this is an interesting subject. However, I work with three two pipe air vent systems, newest from 1885, complete with “gun barrel” (eg nason or bundy) radiators locally manufactured and they are a delight. They’re quiet and trouble free (well NOW they are after the vented returns were corrected and returned to original design).

One can’t assume that the returns are instantly filled with steam. They aren’t. Once everything hits saturation, yes steam enters the returns but by that time the radiator vents are all closed and the radiators heating. The ONLY thing to bear in mind is that you just can’t shut off the supply valve and expect to get no heat at all from a radiator but that’s why the dead men thoughtfully provided a shutoff valve on the return connection as well.

I’m terms of being a flop, it wasn’t. Very soon thereafter the radiator trap was developed and it made for easier plumbing and single valve control.

Interestingly, one site under my care has a few Danfoss valves on the inlets and they actually work well enough to control the room temps, as most cycles are short enough that the returns are effectively lower pressure than supply. So it works, and quite well!

Interesting subject tho

Re: DEAD WRONG

Remember this, nothing has changed from than to today. There are installed systems right and many wrong from application to commissioning. The only difference is the Wanabees cheat their education, their time and their clients, not intentionally unless you consider not getting trained and educated, intentional. What has changed is clients are getting smarter and mfgs. are building more installer proof systems. Some like AO Smith will not let the installer start up the system if they want to keep it warrantied. After all what average installer can afford to replace a $20,000.00 piece of equipment from stupidity. And of course, on this site we are constantly being educated as to how it can be wrong. If you are here, you are among those who want to do it right.

Re: Steam humidifier

We install and service the Aprilaire 800 series..
These units can be installed as a stand along with the fanpack or in a rigid duct with the injection pipe , if you are installing it in a duct it is highly recommended using a "Sail switch" to only allow the unit to work when there is air movement.
The higher end AA Thermostat/humidistats have a "Window schedule" and also base the humidification process on ODR which greatly reduces the possibility for overhumidification.
It also can be hooked up to your WLAN for remote access and notifications.
Hope this helps..

Re: Firomatic as outside shutoff?

The Firomatic is a safety device, not a control valve. Don't mix them up.

Re: Firomatic as outside shutoff?

I would put both a firomatic and a ball valve Use IPS valves threaded for pipe. You can put flare x pipe adapter in where you need them. Look for a ball valve marked "WOG" they are very common WOG is water, oil or gas. Put in the two threaded valve with a threaded nipple between them and flare adapters on the ends if you need to

Re: DEAD WRONG

I can only speak to the plumbing/heating side of things. I go into a lot of old houses. Most of the old stuff, was properly installed. Very rarely see the money business. There is a lot of monkey business/shortcuts in the newer work. More in the renovation end than in the new construction (although I do see it in the new construction as well, just not as common). I was in house today that had some renovations done. Gas dryer vent was venting into the new extension. Indoors. Washing machine drain did not have a trap. About 10 ft of flex gas line. Maybe a little more. No separate gas shut off for the dryer. Dishwasher piping was buried somewhere. Extension cords galore. This is just one example. See crazy stuff all the time. Almost never from the dead men. Obviously a small sample size. Just saying.

Re: DEAD WRONG

......... Just like now, years ago you had people that took pride in their work and did a good job. But at the same time you still had lazy people, you still had greedy people. Nothing has changed.....

Back then, if you were that lazy you lost your job.

Re: DEAD WRONG

I'll take the smell of Horse Manure over Carbon Monoxide & Smog from Vehicles and trucks 🚚 any day.

If you like the smell of horse poo, check out Michigan's Mackinac (pronounced MAK-ə-naw) Island. No cars or trucks allowed!
https://en.wikipedia.org/wiki/Mackinac_Island
Last time I was there, I sneezed the entire day. I suspect I was allergic to something in the horse's diet that went through their digestive tracks, and was then ground into a fine powder and atmospherically dispersed by hooves, bicycle tires, and touron's feet.
Green and sustainable, just like medieval Europe!
