Re: Vidodens 200-W Three way Valve Heating/ IDHW Testing pulling out diverter motor.
Just so everyone knows the motor must hook on to pull out the valve. It will seam to work without doing that, but it needs to hook to pull the valve out. Most times it will work without hooking the end, but that will just fail again. Either it broke loose when it reset the stepper motor or was not assemblied correctly from the factory. Time will tell. Huge thank you Alan

Re: Is this a steam trap?
I had a houseful of these to deal with a couple years ago. But different. And when I cleaned them out (using dental instruments) the house had balanced heating for the first time in 30 years. Or so said the customer.

Re: All Steamed Up has transitioned to new ownership
These guys are amazing and are amazing partners as we take All Steamed Up forward- always looking back at the giants who built this business. Nick is a special guy who loves Steam as much as anyone and will be a great operator.

Re: Is this a steam trap?
It's an O-E Vapor system. That return fitting is a water seal with a small hole in it to let air escape from the radiator. You can find it chapter 15 of @DanHolohan 's excellent book "The Lost Art of Steam Heating"- the latest version is here:
Re: Is this a steam trap?
Wow! We've never known this was a vapor system, even after having two contractors who are supposed to be steam system experts. We are in Ferndale, Michigan, just north of Detroit. I found this in Holohan's book and it looks just like what we have on many radiators, although it doesn't seem consistent around the house. And apparently if we have a vapor system, we shouldn't have a pressuretrol (which we do) and should have a different, more sensitive control for the lower pressure?

Re: Struggling to identify my radiator brand
I have those identical radiators. Somewhere on this site there is an edr sheet for them but I’ll attach mine. Steamhead is 100% correct

Re: Struggling to identify my radiator brand
It's an Eastwood, made by Pierce, Butler & Pierce which was based in Syracuse, NY.
This is true. Any chart for similar rads will work. On page 148 of E.D.R., we see a similar Aero rad made by National Radiator Corp. is rated 35 square feet.
Re: Taco needs to create an animation of how the 570 series zone valve works.
Not to me!
I consider cutaways an excellent training tool. Most hands on people like to know what is happening inside. We get a lot of ah ha moments.
Cut one open for training your own team if nothing else.
Caleffi produces dozens of cut away cases every year for reps and wholesalers. The trade schools snap them up also.
I clamp my PortaBand, with a coarse blade for soft metal, in the vice to slice open these valves. Spray paint, clear coat them.

The Hidden Hydronic Problem Nobody Checks: Water Velocity
This week's video talks about why the speed of the water in a hydronic system matters. Too slow and the air gets trapped. Too fast and you get noise and eventually leaks.
