Re: Hodge Boiler Plant Photo (1890s)
When they rebuilt the Longfellow Bridge in Boston a few years ago, they trained ironworkers in old school hot riveting because they wanted to keep the historic construction accurate. They did a beautiful job, too!

Re: The “Good Deed”
OK GW…. there is this thing called a power switch that you can toggle off and on in order to make the chance of letting factory installed smoke out of transformers. They are very easy to operate. For the most part if the electrician did his job properly, you just toggle the handle to the down position before you put your screwdriver inside the control. here is an example of what the switch might look like.
Hope this helps you in the future.

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.
