Guide to Choosing a Solar Water Heater

Direct solar water heating systems, also called open loop systems, circulate household water, which we use to shower and wash our hands, from the water tank to the collectors and back. On the other hand, indirect or closed loop solar water heaters use a heat exchanger to separate your water from a heat-transfer fluid, usually antifreeze that circulates in the collectors and piping

What is a closed-loop solar system?

(b) Indirect type (closed-loop system) In a closed-loop system, the incoming water is not heated up directly at the solar collectors. Instead, a working fluid (e.g. freon, propylene glycol, distilled water) is employed in the collectors and circulates in a closed loop.

How does an open-loop solar system work?

The function of this open-loop system is illustrated in Fig. 6. After being heated by solar energy, the water is returned to the storage tank for later use. It should be noted that both the collector and storage tank can be positioned either above or below each other depending on various factors.

What is the difference between open loop and closed loop solar systems?

Closed loop systems are slightly less efficient than open loop systems as there is some heat loss through the heat exchanger. Their advantage is that they can use a freeze-resistant fluid so are more suitable for frost-prone areas. For both open and closed loop systems, reduce heat loss between the solar panels and the storage cylinder by:

What are the different types of solar water heating systems?

Solar water heating systems can be divided into 2 categories, the direct type (open-loop type) and the indirect type (closed-loop type), depending on whether the incoming is heated up directly or indirectly via a heat exchanger. (a) Direct type (open-loop system) (Source for above: Southface)

How does a closed loop water heating system work?

In a closed-loop water heating system, potable water is never exposed to the outside environment: A separate loop is used with a fluid that is heated. Generally, this fluid is a propylene-glycol mixture that is heated and sent to a heat exchanger, where the heat is transferred to the potable water.

How does an open loop system work?

In an open loop (direct) system, water heated in the collector panels goes back to the cylinder and then to taps and appliances for household use. A system such as a temperature controlled pump to allow hot water to be circulated through the panel on cold nights to prevent freezing must be integrated into the circuit.
