Drainback solar thermal systems: A review

A drainback system corresponds to a "solar thermal system in which, as part of the normal working cycle, the heat transfer fluid is drained from the solar collector into a storage device when the pump is turned off, and refills the collector when the pump is turned on again" (ISO, 1999). This unique attribute to empty the collectors and to

6 FAQs about [Solar drainback system Norway]

What is a drainback solar hot water system?

A drainback solar hot water system is a type of active solar water heater. In a drainback system, the collector is not continuously filled with water like in other types of systems. Instead, it only fills when there is sun and heat available to be collected.

What is the difference between a drainback solar thermal system?

The only differences are other operation conditions and the control strategy of the pump. When the pump is stopped, a gravitational draining process occurs automatically. The draining has a protective function for drainback solar thermal systems. Empty collectors exclude both overheating problems during stagnation and frost damages in cold periods.

Are drainback systems a safe solution for solar DHW installations?

Drainback systems as an efficient and safe solution for solar DHW installations: practical experience. In: Proceedings of the ISES Solar World Congress 2011, Kassel, Germany, pp. 621–632. NABCEP, 2012. Solar Heating Installer Resource Guide. North American Board of Certified Energy Practitioners, Clifton Park, New York, USA.

What is a drain back system?

At Adveco, we are proponents of systems that deploy drain back, which as the name implies drains the solar fluid from the collector to a reservoir when not in use, allowing for a system to be safely off. A drain back vessel located in the plant room is one option, that will also allow for pipework fluid, but will require greater head pumps.

How does a drainback system work?

In a drainback system, the solar collector is usually mounted on the roof, and the fluid in the collectors is circulated by gravity. When there is no sun, the fluid drains back down into a reservoir tank located below the collectors. This type of system can be used in both residential and commercial applications. What is a Drainback Tank?

What are the operating modes of a solar drainback system?

Operating modes of the drainback technology are systematically evaluated: filling, operation, and draining. Hydraulics of drainback systems are described. Variety of components and associated requirements are presented. Although solar drainback systems have been used for a long time, they are still generating questions regarding smooth functioning.
