I’m replacing my roof. Can my FAFCO system be removed and then put back on my new roof?
Your FAFCO installation professional can easily accommodate the removal and re-installation of your new system and can coordinate this process with the roofing contractor.
How does my solar hot water system know when to turn on and off?
This automatic solar controller turns the solar system on and off when solar energy can be added to your water heater. The controller activates and deactivates based on the temperature difference between the solar sensor mounted on the roof and the water tank sensor mounted on the water heater or solar storage tank. The controller’s temperature differences are 10oF to turn on the solar system and 4oF to turn off the system.
How do I read the tank and roof temperatures for my solar hot water system?

The controller defaults to show the temperature at the bottom of the water heater or solar tank (T-2). To alternate between viewing the temperature of sensor 1 (roof) & sensor 2 (tank) or the temperature difference between sensor 1 and 2 (differential temperature), press the “down arrow” key until the desired temperature reading is shown in the display.

Note: Hot water to the home is drawn from the top of the water heater where the water is the hottest.

Can I use the FAFCO system with a boiler system?
If a boiler is used to provide hot water to the home, the FAFCO Solar Domestic Hot Water System can be used with a solar storage tank to preheat the water for your hot water heater, thus reducing the load on your boiler system.
What if I want even more hot water, for longer showers, etc.? Can I adjust my solar hot water system settings?
The controller is factory preprogrammed to maximize utility electric bill savings. The controller will activate the bottom element of your water heater tank at night when the solar heater is not operating and provide for hot morning showers. Only a FAFCO dealer is authorized to reprogram the controller and altering the factory settings may reduce electric bill savings.
Will the FAFCO system work with my existing pool equipment, or will I need to upgrade my equipment? How large of a pump will I need?
