Uruguay solar drainback system

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.

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 drain back module?

A simple gravity-driven process within the compact module Drain Back module ensures trouble free operation and system longevity for improved returns on investment in renewables for water heating in commercial buildings. Designed for single-row roof-mounted and console systems. Fully compatible with Adveco Flat Plate Solar Thermal Collectors

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 problems does adveco drain back solve?

Adveco Drain Back counters these problems, as well as issues relating to high system pressure, dirty pumps and non-return valves, plus corrosion from acidic heat transfer medium all resulting from very high temperatures seen in modern solar thermal systems.

Does sunoptimo recommend a drainback system?

Sunoptimo prescribes the drainback system which allows the collectors to drain each time the pump stops.
