FAFCO Hot Water

How It Works

FAFCO solar hot water systems are designed to operate automatically, gathering the sun’s energy when available. When solar energy is unavailable, the system turns itself off and the hot water is stored in your water tank until it is needed.

FAFCO solar water heating solutions are designed to work with electric, natural gas, or tankless(instantaneous) water heaters. Your current system and hot water requirements will determine the configuration of your solar hot water system.


  1. Although a single-tank configuration can be utilized for installations with an electric heater, a dual-tank configuration, which includes a dedicated solar hot water tank, is a desirable option in many cases.
  1. A dual tank configuration is required for installations with a gas water heater. One of the tanks is used to hold just the water heated by the solar collectors.

Depending on your needs and the selected configuration, a FAFCO installation by Fun in the Sun may be as quick as half a day.
