Titanium Glass Solar Water Heater – Closed Circuit

The Titanium Glass Solar Water Heater by Wilco has been designed to provide stable and efficient hot-water production throughout the year. Titanium enamel technology in the inner tank ensures long-term protection against limescale and corrosion, while the high-density insulation minimizes heat loss, keeping the water hot for longer—even overnight or on cloudy days.

The selective solar collector, with a titanium-oxide absorber surface, maximizes performance even under low sunlight conditions, offering high absorption and low losses. FULL PLATE construction ensures ideal heat transfer, while 4 mm safety glass provides resistance to pressure, hail, and harsh weather.

The system base—available for flat or pitched surfaces and in a low-profile version—ensures stable mounting and excellent anti-corrosion protection. Its robust galvanized construction allows use in any environment, from coastal areas to mountainous installations with higher wind loads.

The closed circuit of the solar water heater provides additional safety and protection, as the heat-transfer fluid circulates in a separate circuit without coming into contact with the domestic water. This prevents freezing and ensures stable performance even in low-temperature areas.

The Titanium Glass solar water heater by Wilco is available in capacities from 120 to 300 liters, covering needs from a small apartment up to a large family of 7–9 people. With Wilco’s long-standing reliability and build quality since 1975, this system is one of the surest choices for real energy savings and consistent hot-water supply.
