Drainback Solar Hot Water Tank Sight Glass
Drainback Systems are the simplest Solar Hot Water Systems to purchase/install, and require far less maintenance than any other type of Solar Hot Water System. Additionally, Drainback Solar Hot Water Systems can be installed anywhere in the United States because of their simple, gravity based freeze protection, which is as efficient (or more so) as a pressurized glycol system.
The unique component of a Drainback Solar Hot Water System is the Drainback Reservoir, which allows water, or a water-glycol mix HTF to drain out of the Solar Collectors and the manifold when the system is inactive, preventing the HTF from sitting in the manifold and exterior piping, which prevents freezing and also extends the life of the manifold and solar collector in general.
There are several distinct advantages that a Drainback Solar Hot Water System has over other Solar Hot Water Systems. These advantages include:
- Gravity is fail-proof and maintenance free – either water, or a glycol mixture may be used in the collector loop
- The system is not damaged if the pump fails to run and the system cannot reverse thermosyphon at night
- The Collector Absorber Plates last up to 3 times longer than in a Pressurized Glycol System
- The Water/Glycol Mixture never needs to be changed like in a Pressurized Glycol System
- Most local codes do not require a double-walled heat exchanger in an unpressurized system
- The homeowner can easily add Distilled Water to the system without need of a visit from the system’s installer
- There are far less moving components to fail (eg. check-valves, air vents and expansion tanks) which dramatically reduces the need and costs of maintenance
And, the biggest advantage of a Drainback Solar Hot Water System is the High-Limit feature of Differential Controllers – this means larger collector areas per gallon can be sized than pressurized glycol systems – ie, one gallon per 1 sq ft of collector space.
