Solar Hot Water Systems

What it does

Flow Dynamics supplies solar hot water systems across the UAE, where solar irradiance averages above 2,100 kWh/m² per year, among the highest in the world, making solar thermal one of the most cost-effective hot-water technologies available in the region. The range covers flat-plate and evacuated-tube collector fields, thermosiphon rooftop kits for villas, and engineered forced-circulation plants for hotels, labour accommodations, and industrial process water. Collectors are SRCC / Solar Keymark certified for Gulf UV and temperature exposure.

The working principle

In a thermosiphon system, a collector mounted below the storage tank heats water that rises naturally into the tank, no pump, no electronics, no moving parts. In a larger forced-circulation plant, a differential controller compares collector temperature to tank temperature and starts a circulation pump whenever the collector has useful heat to give. A glycol primary loop transfers the heat through an indirect coil in a solar-ready calorifier. An auxiliary heat source, electric, heat pump, or boiler, tops up the tank automatically during low-sun periods.

Where it's used

Typical installations across the UAE and wider Gulf include:

• Villa and residential rooftop systems
• Hotel and resort central hot water
• Labour accommodation and staff housing
• Schools, hospitals, and public buildings
• Industrial process water pre-heating
• Swimming pool heating
