Solar water heating also called solar domestic hot water
systems, can be a to generate hot water for your home. They can be
used in any climate, and the fuel they use sunshine is free.
Solar water heating systems include storage tanks and solar
collectors. There are two types of solar water heating systems:
active, which have circulating pumps and controls, and passive,
which don't.
Most solar water heaters require a well-insulated storage tank.
Solar storage tanks have an additional outlet and inlet connected
to and from the collector. In two-tank systems, the solar water
heater preheats water before it enters the conventional water
heater. In one-tank systems, the back-up heater is combined with
the solar storage in one tank.
6. solar water heating system type:
1) There are two types of active solar water heating
systems:
A: Direct circulation systems
Pumps circulate household water through the collectors and into
the home. They work well in climates where it rarely freezes.
B: Indirect circulation systems
Pumps circulate a non-freezing, through the collectors and a .
This heats the water that then flows into the home. They are
popular in climates prone to freezing temperatures.
2) Passive solar water heating
systems
Passive solar water heating systems are typically less expensive
than active systems, but they're usually not as efficient. However,
passive systems can be more reliable and may last longer. There are
two basic types of passive systems.
These work best in areas where temperatures rarely fall below
freezing. They also work well in households with significant
daytime and evening hot-water needs.
Water flows through the system when warm water rises as cooler
water sinks. The collector must be installed below the storage tank
so that warm water will rise into the tank. These systems are
reliable, but contractors must pay careful attention to the roof
design because of the heavy storage tank. They are usually more
expensive than integral collector-storage passive systems.
Solar water heating systems almost always require a backup
system for cloudy days and times of increased demand. usually
provide backup and may already be part of the solar system package.
A backup system may also be part of the solar collector, such as
rooftop tanks with thermosyphon systems. Since an
integral-collector storage system already stores hot water in
addition to collecting solar heat, it may be packaged with a for
backup.
