Re: AO Smith Gas Water Heater Warranty Replacement
Hi, Is the tank itself actually leaking? If not, I'd replace the cold-side plumbing down to the tank, replace the anode rod and keep going. I'd also use a different plumber. The old gate valve should have been replaced, along with having unions at the hot and cold connections. In the West, we almost always use flex connectors, which would have prevented any strain on the copper sweat joints and given unions. 🤠
Yours, Larry

Good that it is now working.
Hopefully now you understand more than you ever really wanted to know about your boiler's wiring.

Re: high velocity ac
I understand all that believe me. The factory is the one who instructed me to have lined inside in this application-I have installed these systems for 30 years
Re: Staged boiler retrofit design questions
I think a hydronic separator is just the ticket! Great suggestion, thank you @hot_rod !!

Re: Staged boiler retrofit design questions
hydro seps are more common for combining boilers
You get air, dirt, magnetic and hydraulic separation with one component

Re: Staged boiler retrofit design questions
Looks like they had pumps on the old boilers at one time as the flanges are still installed.

Re: Can I use new oil boiler to replace old? Old is leaking. Old has vent, looks like new does not? TY
That’s not a DIY project. Get someone who knows what they’re doing.
Improper installation of a boiler can cause an explosion or CO poisoning.

Re: Where can I add a scoop and air vent
Sorry for the late response. Thank you very much for your explanation and the drawing on where to put the Discal air separator! I'll be sure to ensure that when I have a new boiler installed, the installer is experience with residential boilers and piping. I'll also review the book that you recommended.

Re: Unico potable water furnace, expansion tank pressure
whats the normal static fill pressure? and does this system also provide DHW or is it heat only? a boiler system on a with an attached fresh water supply would have a pressure reducing valve installed, is there such a valve on this system or is it just taking in city pressure?
