Re: AC BTU Sizing question
The compressor ratings plate may give you sone idea of the size.
The 1 ton would be way oversized no matter how you look at it, my 800 ft^2 house in michigan is probably 1.5-2 tons. The hallway adds some load but unless you have a fan to circulate air between the 2, don't count on it adding much load. Even the 9,000 btu/hr will short cycle in that space but will probably be manageable.

Re: The “Good Deed”
I've got one too many "no good deed goes unpunished" stories. Guys like us always do the right thing and eat the cost. What I have learned to do in these situations is not touch ANYTHING until you are 100% clear with them, maybe in writing, that you are doing them a favor, but not responsible for any parts or labor incurred.
Don't beat yourself up Gary, we work in cramped conditions and its very easy to cause a dead short. Burned out plenty of transformer learning...Mad Dog
Re: Any plumbers good at small bathroom layout?
You might consider viewing a few RV manufacture sites to see their bathroom layouts and fixtures. They seem to specialize in tight spaces😎

Re: How much does size matter?
that calculator gives me a load of 103,554 BTU/hr. My boiler is an 85k mod/con and when I checked up on it this past winter when it was -15f outside it satisfied a call for heat in less than 10 minutes. That calculator is pretty far off, that being said a 125k with a 10:1 turndown is going to be fine, I just don't think your actual load is anywhere near what SH suggests.

Re: Biological control for filler station
On a closed system there is no need for bio control in most cases.
If you are using your potable hot water heater for heating both the water you shower with and the floor heat, then stop doing that. There will be bio hazard issues that you don't want to have near you in the shower or the kitchen. Your closed loop system and your Domestic Hot Water (DHW) need to be two separate systems.
What is a filler station?

Re: Co-op in Brooklyn looking for steam consultant, 120 unit, single pipe, 1950s building
To All,
This is not an opinion based on one day. Yesterday my burner did not start again [6th time this summer]. I don't care about other power grids. As for New York City and my area, You can go on the local utilty's web site and look at the power outages and voltage reductions that they list. They are required by law to notify you in New York for reductions of 8 percent. My location in Williamsburg of the past 5 years has had an increase in high rise buildings and residential housing and associated loading . I had to call the company that services my steam boiler 3 times in the last heating season at a cost of $1,800 because of this problem and the damage caused. That is why I mentioned people in my situation install the AVR in their steam systems to prevent this. The shareholders in a Coop who spend $500,00 for their units do not want to hear about power grids or even local law 97 compliance. They want the problem solved, preventative measures taken and their maintenance cost foe their steam system kept low.
Re: Replacement PTAC system for a Singer
some manufacturers put ratings plates in where they are hidden in use, like on the side somewhere where the sleeve blocks it.
