General Description from Customer:

I am building a custom fireplace in a meditation room that will be built of compressed straw bale wall construction with a super insulated roof.  The room will be 100% passively solar heated except for the very rare times when the sun does not shine for 2 or more consecutive days in Southern Colorado, or temperatures drop below -20° F for extended periods.  During those times, the fireplace will be used to provide additional heating.  Due to the basic inefficiency of fireplaces vs. wood stoves, I am installing a copper coil heat exchanger in the top of the fireplace which will connect with closed loop in floor radiant heat tubing buried approximately 2” in the poured adobe floor.  The switch will activate a 120V 60W Taco 007 pump to circulate the water to the floor loop when the tubing above the fire reaches approx 120° F and will deactivate the pump when the temperature of the coil is approximately 70° F.  It may cycle a couple of times in the beginning because the water initially returning from the floor loop will be approx. 60°, but as heat is transferred to the adobe mass, the returning water will quickly warm up to above the open set point and then there will be constant operation until the fire burns low and the coil cools to below 70° F.

Our temperature switches work by using a bimetal disc. The bimetal disc in the switch reacts to heat, and opens or closes a set of contacts based on what the ambient temperature is. This is works because the different metals in the disc react to heat in different ways, which causes the disc to bend.
