Solar hot water systems like the ones offered by HCB solar can provide the necessary heat for warm showers and baths, dishwashing and cleaning. They offer a cost effective unit. They may be used in any climate and transfer heat from the sun into the pipes of the home for virtually free energy. Most are very reliable and require little if any service.

• Solar hot water systems like the ones offered by
HCB solar can provide the necessary heat for
warm showers and baths, dishwashing and
cleaning. They offer a cost effective unit. They
may be used in any climate and transfer heat
from the sun into the pipes of the home for
virtually free energy. Most are very reliable and
require little if any service.

• These units include storage tanks and collectors.
An active system uses circulating pumps and
other controls. A passive unit does not use
pumps or other types of controls. While the
latter is generally less expensive, it is also less
efficient. An installer can help guide
homeowners to choose the system that can best
meet their needs.

• The types of active units can be further divided
into units using direct circulation and those
relying on indirect circulation. The direct
circulation system pumps the product to be
heated through the collector and back to the
storage tank. These devices are best in climates
where temperatures rarely drop below freezing.

• An indirect circulation system is better in areas
where freezing temperatures might be a
problem. These units pump an antifreeze
solution through the collectors where it is
heated. Inside the storage tank, the solution
passes through a heat exchanger to warm the
product inside. This type system can be
combined with a traditional one for days when
the sun does not provide enough heat.

• Integral collector units work best in locations
where the temperature rarely drops below the
freezing mark. They are ideal for homes where
the most significant needs are during the
daytime. Thermosyphon units require the
collector to be installed below the tank, allowing
it to naturally move back up and circulate. While
the devices are reliable, the builder must ensure
the roof can support the extra weight of the filled
tank.

• Collectors fall into one of three types. The flat
plate collector is an insulated and weatherproof
box that is lined with a dark absorber under
layers or plastic or glass. The integral collector
units have black tubes or tanks in a glazed box.
These use some type of backup system to add to
the heat. Evacuated tube collectors are more
common in commercial applications in the USA.

• Once HCB solar hot water systems are installed
they do require proper maintenance to ensure
they run smoothly. Active units require more
maintenance than passive ones. In fact, most
simple passive units require maintenance only
every three to five years. Units that have
electrical components may require replacement
of some parts after approximately 10 years.
