There are two main types of solar water heaters, open loop and closed loop. Closed loop systems are more commonly used for domestic water heating. Proper installation and maintenance is important to avoid common problems like pump failure due to entrapped air, insufficient expansion tank size leading to pressure issues, broken sensor wire connections causing pump malfunctions, and mineral deposits damaging valves and tanks over time. Professional installation is recommended to minimize these risks.

Roof Mounted Solar water Heater

2. Basically, there are 2 types of solar water heaters. One
is the open loop solar water heating system, which is
relatively expensive and the other is closed-loop solar
water heating system, which is often used to heat water
for domestic use.

3. Pump failure can also be caused when the air within
the solar piping loop becomes entrapped in the
impeller cavity, thus resulting in loss of suction,
burnout and freewheeling. While there are a number
of effective ways for removing air from the piping, it
is best to entrust the job to a professional.

4. Perhaps, the expansion tank is one of the most important
components of a solar water heater. Expansion tank helps to
release the water pressure. If you install solar water heater
in a smaller expansion tank, there might be excessive
pressure that can result in the failure of different parts of
the system. Also, if the expansion tank remains untreated for
long, it can lead to the corrosion of the unit, thereby
resulting in a complete breakdown.

5. A sensor wire signals the pump when to turn on and off. If
the contact between the pump and the sensor breaks for
any reason, it can result in a number of unwanted
consequences. For example, the pump can burn out or
malfunction.

6. Solar water heaters tend to malfunction if mineral
and other debris deposit in the system. It can damage
the valves and cause tank failure.
