I can’t let you get the last word :-)

After I get some of my other projects caught up the electric heat is something I have to investigate. Currently you need to turn on the switch on the KIB panel then turn on a standard light switch next to the sink then turn on the switch underneath the sink next to the other propane water heater switch. Three electrical switches to turn on the electric water heater element???? Not sure what does what but you have to have all three of them on for it to work.

As I typed this on my phone I was running this scenario in my head. The switch to the left of the sink is the 110 the switch under the sink is the switch to turn 12 V propane igniter or energize the 110. The switch on the KB panel is the master on/off.

Just seems like a lot to heat water

Interesting.

My 110 runs right from the breaker under the bed to the switch near the batroom sink, then to the shut off switch right on the heater, which is normally left on. Normally only the switch by the sink is used.

My LP is controlled by a single 12V feed from the KIB board switch. It appears the two systems are completely independent.

Another example of Barth variation.
