Re: Math Problem
Ratio is correct.
To put it into algebra. For each person staying (a-g) replace the letter with the number of nights they are staying so:
(a+b+c+d+e+f+g) * x = $3,572
where x is the cost per person-night.
x = $3,572 / (a+b+c+d+e+f+g)
Then the actual cost per person is
a*x = Cost for a
b*x = Cost for b
etc

Re: OT Electric: Hedgetrimmer & Other Ext Cord Choices
My refrigerators are wired with 18 gauge wire and plugged into a 20A circuit.
Many modern refrigerators, lamps etc are still wired with 18 gauge wire, 16 if you're lucky.
A 16 gauge ungrounded cord is perfectly acceptable.
If you draw 15 amps on that 16 gauge cord over 50 feet all that's going to happen is excessive voltage drop and the cord will feel warm.

Re: OT Electric: Hedgetrimmer & Other Ext Cord Choices
16 gauge cord is fine on a 15 amp circuit especially with the small load you have. Using a larger cord with a short piece of 16 gauge is a good idea as it will limit voltage drop although probably not necessary with the small load.
Plug into a GFCI receptacle if you can.
The trimmer is not internally grounded it is considered double insulated.
Re: Multiple steam boiler piping concept
but...
I'm a little concerned about the check or non-return valves. Ive not had really good luck with valves on saturated steam lines, unless they are full port plug or ball valves -- but those don't operate as non-return or check valves by themselves. I wonder if, at the expense of some complexity (which I hate!) if you might need to use a motorized full port valve, opening on a signal from the boiler that it (the boiler) is up to steam...
Re: AFCI Circuit Breakers
I put four Square D QO combination arc fault/ground in when I upgraded my service in 2017. The only nuisance trips I’ve had were caused by a pretty fancy computer running graphics intensive software. Otherwise they haven’t been a problem at all.

Re: AFCI Circuit Breakers
I've had a couple of QO breakers installed next door for several years now, I'm unaware of any issues with them. I did exchange one during the initial install, as it didn't trip when I used my Amprobe ACFI tester (INSP-3). I later heard that the only legit test is the test button, so take that with a grain of salt.

Re: AFCI Circuit Breakers
Not sure if any brands are exempt from random tripping.
Sq D Qo has usually been considered the top of the line for years even used on commercial jobs FWIW. Don't know how their GFCI/AFCI breakers are holding up. Will try and find out.
Re: Wood Stoves with Outside Air Intake (Benefits/Disadvantages) - (Catalytic/Non-Catalytic) ?
My catalytic stove was more trouble than it was worth. It required constant attendance. New stove with secondary burn is much better. A leaky old house does not need a fresh air intake.
Re: Wood Stoves with Outside Air Intake (Benefits/Disadvantages) - (Catalytic/Non-Catalytic) ?
@LS123, we have a category for this on the forum called Biomass.
The Alliance for Green Heat's website is an excellent resource for information about wood and pellet stoves. I enjoy their monthly email newsletter too.
