Suppliers that help with supply detail and design of Radiant Heat
When I did my Solar I called AltE store and told them what I wanted, and they put together a quote of everything I needed, and it all worked out in the end.
Are there similar suppliers for Radian Heat?
My heating source is not common (Sanden Eco2), but from a plumbing perspective, it's just a two zone radiant system with two heat exchangers (pre-heat with drain-back solar system and exchange heat via required Taco x-block with Sanden Eco2 tank).

Re: Importance of outdoor temp sensor for reset on Viessmann Vitodens B1KE-120 ?
@GGross I thought Viessman had 0-10v control but called it something else.The 200 series has a 0-10v. Older Viessmann equipment utilized 0-10v but instead of the 0-10 correlating to a burner operating percentage it corresponded to a setpoint temperature. Viessmann doesn't like external controls operating their burner. I believe the new 0-10v is more in line with US needs but not entirely sure.
You may be thinking about the european "open therm" which I am pretty sure is very similar to how we use 0-10v controllers. Viessmann used open therm controls as their own form of room feedback or indoor reset. most of the 200 series boilers have this capability if I'm not mistaken.

Re: Venting - What's code?
The national standard plumbing code requires the aggregate vent area to equal the required building drain size. (Not the actual size that was installed.)
So if the house requires a 3" sewer leaving the building, your aggregate vent area must be the same in square inches. It does not need to be a 3" pipe, it needs to equal the 3" in square inches, which is two 2" , and one 1-1/2" pipe. Or a 3" pipe of course.
Even if the building drain leaving the building is 4", but the calculations say it needs a 3", that is all you are required to provide in Venting. Most all residential only requires a 3" building drain. (The building drain is the main drain inside of the building, to 3' outside of the building, where it becomes the building sewer. )
The hoar frost portion of the code is not adopted in the NJ edition.

Steam input seems to be block ways to unblock?
Two pipe building, four stories tall, third-floor bath rad no steam out of supply, Replaced Trap, Removed supply shutoff valve, valve full open. All other floors' bath rads are functioning correctly. I am thinking of air pressure on the supply to unblock possibly; any Idea would be helpful. Thanks, Ed. W

Re: Thermostats for Steam/Hot Water Hybrid
There is a standard wiring system that will solve your issue. It is possible that the person that installed the addition system along with the RA832 and the Aquastat missed something and wired it incorrectly. There is also the possibility that the Aquastat is not installed in the correct location and is not stopping the burner when the boiler starts to make steam.
The Aquastat should be installed below the water line in the boiler, not on a pipe that is external to the boiler. I will follow up with the proper wiring diagram shortly. It would be helpful if you posted a picture of the boiler so I can suggest a better location for the aquastat and also know what is operating the steam boiler.

Re: Venting - What's code?
In SF, you need at least one full bore vent stack, usually 4” for residential. Elsewhere (per UPC), you only need to add up all the vents to equal the area of the building drain. Those were tough lessons to learn when you did it wrong, but you always did it right afterwards.
Importance of outdoor temp sensor for reset on Viessmann Vitodens B1KE-120 ?
I'm currently having a Viessmann Vitodens B1KE-120 installed in Palo Alto.
I'm wondering if I should have the included outdoor temp sensor installed and enabled.
Here's what the heating company said:
"We could but we found it a bit problematic at times and customers don't really tend to use it so 95% of the time we come back to remove it . Keeps the boiler from running as temperature rises throughout the day some people like the warm floors. Totally up to you."
Any thoughts on this decision?

Re: How bad is it going to be to repair this leak?
Might want to consider opening the ceiling below for access.
When my customers gripe about cutting access holes, I tell them I can cut it now with a saw and vacuum, or the firefighter can cut it later with an axe.

Re: Speed question about Taco 007 vs. 0015e3
The 0015e3 set on medium speed has a very similar performance to the 007.
When you say you have an issue raising the temperature inside from 64 to 68 degrees, what do you mean?
Does is take an ungodly amount of time or is it different amount of time from month to month and hard to track?
Has it always been that way for the past 24 years or is it a recent issue?
