FAFCO Solar Water Heaters

FAFCO solar hot water heaters 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. 

1. Solar collector panels—made of durable, lightweight, ultraviolet-resistant, polymer material—are designed specifically for hot water heating.
2. When solar energy is available, collector panels heat water pumped through the solar loop.
3. A heat exchanger transfers heat from the solar loop to water in your storage tank where it is available for all household needs. Water in the two loops never mixes.
4. When not in operation, the water in the solar collectors drains back into the wall-mounted drainback tank to prevent water from freezing inside the solar collector panels.

Product Options

FAFCO solar water heaters 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. Comtec will design the system that best suits your needs.

1. A single-tank configuration is standard for installations with an electric water heater. However, a dual-tank configuration, which includes a dedicated solar hot water tank, is an option and may be desirable for large families or homes where additional hot water capacity is desired.

2. 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.
