This water heater is an indirect solar hot water system with a heat exchanger in the solar storage tank.

Closed circuit solar water heater.

Gmoi series family has 150l 200l and 300l solar hot water system. This water heater is a closed circuit solar hot water system with a heat exchanger in the solar storage tank. The premier loline replaces water in the panels with a special heat exchange fluid with anti freeze properties. The closed circuit fluid is propylene glycol concentrate mixed with water.

A drain back solar system is a non pressurized volume of water in a closed circuit that as the name implies drains back from the panels down to a storage tank at the end of every heating cycle. The advantage of a drain back system is built in freeze and overheating protection. The down side is two heat sources. Gmoi series roof top solar water heater.
