Thermosiphon Systems
Roof mounted
All Solahart systems, where the tank is roof-mounted,
use the Thermosiphon principle to collect heat from the sun
and transfer it to your hot water.
The Thermosiphon principle is based on two naturally occurring phenomena:
- Dark objects absorb heat
- Hot water rises
All Solahart collector panels are coated with a dark, heat-absorbent
surface. This coating absorbs the suns rays and heats the cold fluid
in the collector panel.the fluid heats, it rises to the top of the
collector panel and into the tank where it displaces cooler fluid
which flows in to the bottom of the collector panel where the process
is repeated.
As the greater the temperature difference between the fluid in
the collector panels and the water in the tank the faster the flow
between them.
In open circuit systems the fluid in the collector panel is water
while in closed circuit systems a special fluid called, Hartgard,
is used. When heated in the collector panel, it is circulated in
a jacket around the tank to transfer the heat to the water inside.
In this way Solahart systems constantly soak up the sun's energy
to ensure you have hot water, on tap, everyday.
Solahart has several roof mounted systems to choose from.
Solarhart
Jf Free Heat and Kf Series
The roof mounted Kf Free Heat and Kf Series are the ultimate in
solar water heaters. They have been specifically designed to deliver
high efficiency in Australia's cooler climates
and utilise our slimline double-coated ceramic lined tank to provide
years of service.

Streamline Systems
Split
Systems - Ground mounted
Solahart's Streamline is designed to give you, the owner, the maximum
flexibility of installation locations. The low profile and unobtrusive
Solahart collector panels are mounted on a North facing roof, whilst
the storage tank is mounted at ground level out of sight. The electric
boosted tank can even be installed inside your home. This minimises
the visual impact of going solar, while maximising the potential
savings from the sun.
With a Streamline the water is circulated from the
tank and through the collector panels by an electric pump called
a 'circulator'.
Cooler water is pumped in a continuous cycle from the bottom of
the tank and circulated through the collector panels where it absorbs
the heat extracted from the sun before being returned to the top
of the tank.
The circulator is regulated by a control unit on the water heater,
when the controller senses an 8°C differential in temperature
between the top of the collector panels and the bottom of the tank,
the circulator is activated until the temperature differential falls
to 4°C.
Solahart Synergy Systems
Heat Pump
The Solahart Synergy is like a solar water heater
without the collector panels. Instead, it uses amazingly efficient
heat pump technology to extract the heat from the surrounding air.
The Synergy operates in much the same way as a refrigerator but
in reverse. Ambient air is used to warm the CFC free refrigerant,
which converts into a gas. This gas is compressed which generates
heat and the heat is transferred to the water. Once the heat has
been extracted the refrigerant is expanded back to a liquid and
the cycle repeats.
This process is 225% more efficient than conventional electric water
heaters so it uses 1/3 of the energy to provide all a family's hot
water needs.
