Traditional Drainback Systems
Specially designed drainback tanks can convert any regular water heater into a solar water heater!
The Traditional Drainback Kit includes:
• 10-gallon US-made drainback tank with heat exchanger
• Taco 009 Bronze circulator pump
• Taco 003 Bronze circulator pump
• Taco Bronze pump flange set for 009 pump
• Steca TR301 U solar controller
• Brass boiler drain
• 50 psi pressure valve
• Tank stand
• Solar collector
IMPORTANT: Water storage tank is NOT included. This kit installs on the existing stroage tank.
NOTE: Additional fittings and piping are required during the install.
How does a Traditional Drainback Solar System work?
Traditional Drainback Systems use a pump to circulate water or glycol in the collector loop, which drops into a reservoir tank when the pump stops. They also use a differential controller to start the pump (or the pumps) and to route the water into the system. This process begins whenever the sensors attached to the collector detect useful sunlight available (which happens when the temperature in the collector is higher than the temperature of the water at the bottom of the storage tank).
