Central heat and a problem solving triumph…...
For the first time in this homes 140+ history it has a comprehensive central heat and cooling system. Just before Thanksgiving we got the boiler running. So now the house has four independent zones for heat run by four thermostats. In the process of hooking up the thermostat wires we discovered there was a dead short in the master bedroom, bathroom , and closet zone. Basically somewhere in 35-45 ft of thermostat wire the was a place or places where the wire had been crushed or nicked enough to allow the conductors to make contact with each other. Simply put the thermostat is a switch. When it calls for heat it closes and completes the circuit, that in turn starts the pump and the heat is circulated. When it no longer wants heat it opens and ends the cycle. So my job was to find the short or fish 35ft of new wire through framing and finishes that were for the most part inaccessible. The path for the wire sent it up an interior kitchen wall, across the kitchen ceiling, then lastly up to its location on a wall in our master bedroom. The good news it was “relatively inaccessible”. I installed a vent in the kitchen ceiling above our woodstove that supplies heat (passive heat) to our master bedroom, as well as heating our shower seat. My plan was simply to unhook the vent (pictured upper left), push it into the void under the shower seat and look for a way to fish a new thermostat wire. When I removed the vent I found the thermostat wire and was getting ready to start cutting up floor and all the other necessary stuff to fish the new wire to the basement……….then it hit me.
With the thermostat wire exposed I decided to cut the wire, expose and separate the conductors. Because less than a third of the wire was above me it was a long shot, but if the short was in that section of wire I would save myself A WHOLE LOT OF TROUBLE. I ran down stairs connected the splice in the basement…...and short was gone. Somewhere above the cut I just made was where the problem was. I had actually gone to my van to get the saws necessary to start taking flooring up, and was within seconds of starting the demo process when the idea hit me to check for the problem like I did. I don’t normally get excited about problem solving, I do it every day in my job, but the sudden realization that I had figured it out and didn't have to start pulling floors and ceilings apart brought me MUCH JOY! I think for the most part I was surprised because it’s not what I do every day. It would have been one of the first steps in problem solving for an electrician, but I’m not an electrician I've learned a lot renovating this old farmhouse, and some it has been learning look at things from different views……..like an electrician instead of a carpenter.
