Re: Indirect- Going away,shut it off?
Your right about "getting over it" For me it was Ice skating I had a pond within a short walking distance from my house. I would sit in school looking out the window wondering what shape the ice was in. Couldn't wait to get home to grab my skates as soon as school was out. I would miss dinner and get home around 8:00.
Caught a lot of flak because I should have been doing homework…….and my report card showed it.
Then my father and my sister who was a teacher would make my life miserable LOL

I think @hot_rod just rained on the OPs parade.
Re: Water Tanks on Roofs?
i don't know what hotels you're staying in but every hotel i've stayed in in about the past 25 years had a shower with a flow restrictor in it that was like trying to shower with a squirt gun

Re: Replacing gas Navien boiler with electric boiler for hydronic heat?
Rarely is electric cheaper unless you are getting it free from the sun. My son-in-law and daughter both have solar panels on the roof, and they both have electric vehicles. They never visit gas stations and “fill up the tank” while they are asleep. (They are ER doctors often on the night shift.) So there is time saved with that scenario.
I always get them a Gas Card for Christmas. That's the kind of Dad I am.
To the point. the Solar does make the electric less expensive in the long run. But still, I would keep the Gas Boiler and just connect the Electric Boiler or Air to Water HP next to the Gas boiler.
Re: Augusta Stone Church
@leonz
Im glad that burning coal works for you, but am I to understand that you’re suggesting that as a mechanical contractor I should attempt to sell this as a viable solution to the church? Do you really think that they would want to have to have a coal bin installed, find a coal supplier, have someone be there at least twice a day to shovel coal, and put up with the mess that it would create?

Re: Augusta Stone Church
Please do not yell;
I am speaking here as a homeowner with a coal fired boiler heating system and paraphrasing what Brother Jamie has said "Mercy Me, YUCK!!!!!!!!!!"
As you are in an area where Anthracite rice coal can be obtained easily, your heating system can be upgraded with a dual fuel EFM DF520 coal stoker set up for steam heating with some work and reconnect/replace the missing radiators to replace that abomination in my opinion as a lay person.
The EFM DF520 coal stoker boiler has a 3 inch tapping in the steam chest and two 2 inch returns for hydronic heating.
Again I am speaking as a homeowner having grown up with one pipe steam heat; a 3 inch double header coming off the riser in the steam chest makes a great deal more sense with that mess as the 3 inch drop header transitioning to a 4 inch header pipe then rising to meet the existing piping would make much more sense and allow the entire church to be heated eliminating all that excess piping and making a cleaner installation.
You apparently have at least 24 inches in open space above the existing boiler for a double drop header with a drain back to the boiler Hartford loop so it would be an ideal installation to create very dry steam.
The EFM DF520 can be equipped with a dual fuel heating system where I believe natural gas can be the dual fuel used rather than oil.
I am making the popcorn with olive oil and will pass it around here as I wait and see what happens next.
It may be well worth the phone call to EFM in Emmaus, Pa and ask about adding a second riser to the DF520 boiler to increase the steam output more quickly to a double drop header to replace that mess.
Please do not yell.

@hot_rod, that photo was during standby.
You should see it when it is running full tilt
It's a thing of beauty!

@HVACNUT said: "Both R32 and 454B have been used worldwide for years already. I'm not aware of it being banned anywhere. But what do I know. The way things are going, there's probably a Bill out to revert back to ammonia again."
I never liked Bill.
However his sister Janet was pretty hot
