Domestic Solar Water Heating refers to applications such as household hot water. With the increasing cost of electricity, installing an Atlantic Solar Water Heating System makes a lot of sense. A correctly configured Solar Heating system will save you money.

What size system is right for me?
An average person uses about 50 liters of hot water per day.

What installation is right for me?
All Atlantic Solar domestic solar water heating systems can be installed in various configurations to meet our customers needs.
INSTALLATION TYPES:

On-roof installation (Close Coupled External)
On roof installation is where both the solar heating collector and the solar geyser are mounted outside on the roof.
This can be done on a pitched roof slope or on a metal stand on a flat roof.
An on-roof installation has some distinct benefits:
It generally delivers the best results due to the fact that natural thermosiphon is achieved.
It is also more affordable because it requires less installation materials.
Should a component such as a vacuum breaker fail, all water is on the outside of the roof with less potential to cause water damage to the ceilings.

In-Roof Installation (Split Internal)
In-roof installation is where the solar heating collector is mounted outside on the roof and the solar geyser is positioned inside the roof much like a normal geyser would be.
The difference however is that the solar geyser must be placed on a raised platform inside the roof so that it is higher than the collector on the outside. The reason why this is done is to obtain natural thermosiphon. This can only be done in a house with a fairly steep pitch and a high roof line. Generally an in-roof solar system installation is not possible in a house with exposed roof trusses or no ceiling.
An in-roof installation is more aesthetically pleasing but because more materials is needed it is generally more expensive than an on-roof solar installation.

Forced circulation /pump assisted systems (active systems)
Forced circulation systems refers to a solar installation where natural thermosyphon can not be achieved because the solar geyser is positioned lower than the collector.
Circulation of hot water is forced between the on-roof solar collector and in-roof solar geyser by a circulation pump.
