6 FAQs about [Direct solar heating system]
Do I need a direct or indirect solar hot water system?
When installing an active solar hot water system, you'll need to decide between a direct and indirect setup. Direct systems heat water directly from the sun, while indirect systems use a different fluid to transfer heat from your collectors before heating your water.
How does a direct solar water heating system work?
Explaining the Competition: Direct solar water heating systems pass potable water through the thermal collector that eventually flows directly to the desired application (the faucet, the showerhead, etc.).
What is the difference between a direct and indirect solar system?
In an indirect system, solar energy is collected and held in a special antifreeze fluid. The antifreeze is circulated into your hot water storage tank, which heats water for use in your home. By comparison, in a direct setup, your water gets heat directly from the sun, rather than being collected in a transfer fluid first.
How does a direct heating system work?
Direct systems work well in locations where water isn’t going to freeze, because plain water is pumped outside and back in again during the process. A direct heating system is pretty simple—a single loop that moves the water from your home to be heated and back to it again.
What is a solar water heater?
