The footings have been poured with full depth pea rock for drainage under foundation. The Thermal
Storage Tank has been set. The copper pipes are sealed on the inside and outside Twelve inches of high density foam
insulation is going on the sides and top of tank. The tank is to be sealed to prevent leakage due to thermal expansion.
Two pipes are for sensors. One sensor is at the top of the water level and the other is at the bottom. Two
pipes are for the heating loop and two are for the solar loop. Specific information on the heat exchanger and material
used inside the tank are private at this time.
