Drainback solar boiler | Sunoptimo Solar Thermal

A system based on drainback, also called a self-draining or gravity drain system, allows the solar collectors to drain naturally and passively every time the circulation pump stops. The fluid is thus immune to overheating and freezing. The fluid in the collectors drains back down into the drain tank installed in the boiler room.

6 FAQs about [Drain back solar system Iceland]

What is a drainback solar hot water system?

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.

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.

What is a drainback tank & how does it work?

This type of system can be used in both residential and commercial applications. What is a Drainback Tank? A drainback tank is a type of solar water heater that uses gravity to circulate water from the collector back to the storage tank. When the collector is not in use, all of the water drains out of it and into the storage tank.

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.
