Drain Back Solar Systems
Drain back systems are versatile: ideally suited for both cold and warm regions. The drain back process protects solar system components from both freezing and overheating, and saves power by shutting down the solar system when there is no longer a demand for hot water. Drain back systems have fewer components than pressurized systems, making

6 Frequently Asked Questions about “How to make a solar drain valve”
How to arrange plumbing in a solar loop?
There are two main choices for how to arrange the plumbing in the solar loop, drain-back and pressurised solar systems: When the pump is not running in a drain-back solar system, all of the liquid is inside the building and the solar panels are empty of fluid.
What are the advantages of a drain-back Solar System?
The advantages of the drain-back solar system are: In a pressurised solar system, the solar circuit is completely filled with liquid at all times, including overnight in freezing weather and during periods of stagnation.
How does a solar pump work?
If there is heat to be collected from the solar panel, the pump is energised by the solar controller, and starts to push liquid up and over the top of the circuit. The level of fluid in the drain-back vessel is lowered until the point where liquid has filled all of the pipe-work above the drain-back vessel.
How does a solar panel heat pump work?
The circuit is now complete and heat is transferred from the solar panel to the hot water cylinder. When the pump switches off (for example at night time or if the cylinder reaches its target temperature), the fluid flows backwards under gravity down the solar panel until both sides reach the resting fill level again.
How does a pressurised Solar System work?
In a pressurised solar system, the solar circuit is completely filled with liquid at all times, including overnight in freezing weather and during periods of stagnation. To prevent burst pipes in the solar panel the circuit is filled with antifreeze solution, around 40% by weight of propylene glycol will protect the solar panels down to -20C.
How does a solar water pump protect from stagnation?
This arrangement protects the solar fluid from temperature extremes that can occur overnight in winter and during "stagnation" in summer. Stagnation is the condition when the pump is switched off during sunny weather (for example because the hot water store is already at its maximum temperature).
