Re: Radiant Snowmelt Tubing Size and Placement- Under Eaves
Here are the classifications of snowmelt design. Bottom line…how much snow and how quickly do you want to melt?
Of course the faster the desired melt, the more boiler power you need. I would guess 200 btu/ sq ft or more for a system like that.
What will it be powered by, it will not be a cheap date to run.

As long as there is not too much Chinesezium in the welding rod used.
Re: If you are not using AI....
I've had good results by asking very specific incremental questions that lead up to the answer for the bigger question. You can sort of hack the AI into showing its work and giving correct answers to smaller problems. Then you can ask it to consider it's previous answers when answering the bigger question. But yes, definitely be careful! I was working on some website integration coding stuff (of which I have zero knowledge) and using ChatGPT to guide me through the process. I had some initial success, but once it got really technical it led me on an hours long circular wild goose chase. One of the harder things to calibrate for initially is unbridled confidence with which answers are given. It's like your buddy who "knows" everything, but really knows pretty much nothing 😂
Re: Electric Anode rods
Hi and yes, @mattmia2 . But it's sort of a bean-counter's guess. How can the manufacturer know in anything other than a very general way what water the heater will see? Powered rods cost more, but might be a better one-size-fits-all solution. 😎

Re: Off grid heating/ac minisplit efficiency
Hi, My experience with off grid stuff has been clear that pure sine wave power is needed for electronics. Even modified sine wave is considered to be "dirty power" and makes electronics get all glitchy. Even LEDs have problems with anything but clean power.

Re: Steam Take-off piping
If you also put a drip back to the boiler return off the end of that extra header, it should be OK. Otherwise you may have problems. But why? Surely it might have been possible to find a harder way to pipe that?
Re: Boiler
On the other hand, I see a lot of decades-old Burnham Series 2 boilers, including newer variations like the ES2 and the Series 3……….
Re: Is the circulator pump too powerful?
The Taco pump for the 3rd floor has an internal flow check which is stuck open or has some debris in it. It’s in (or should be) the discharge side of the pump. Fix that and your problem will be resolved.

Re: do you really need a thermal expansion tank
If there is any form of check or non-return valve on that domestic system, then yes you need an expansion tank on the hot water, unless there is a well pressure tank AFTER the check or non-return valve.
Don't debate the issue — just do it.
