Drain Back Tanks are designed to allow the solar collectors to drain all water from the collector and related pipe connections into the drain back tank reservoir to protect the system from freezing and overheating. Drain Back Tanks come in two configurations; the internal heat exchanger model is used with a plain storage tank or electric water heater tank. The model without a heat exchanger is used with a solar tank with an integral heat exchanger or with a system using an external brazed plate heat exchanger. Drain back systems are a smart choice when designing a solar thermal system to supplement central heating and domestic hot water heating components. Maintenance is reduced when compared to a pressurized glycol system.
