A Fagor Solasis 15 litre gas water
heater, sold locally by ADCENG Gas Equipment |
ADCENG Gas Equipment, South Africa’s largest gas
equipment and solution provider, has taken energy saving into a new
realm by combining gas water heaters with solar water heating panels.
“Gas water heaters are in themselves extremely frugal but when
combined with solar water heating panels, energy savings are huge,”
says the Appliance Brand Manager
Two solar compatible water heaters, the Fagor Solasis 15 and 11 litre
models are available from ADCENG, both of them specifically designed
to link up with solar water heating systems.
The panels are available from Energy Efficient Options, a Cape
Town-based company which has been contracted by the National Parks
Board to install several gas/solar systems at various resorts
countrywide.
“The Solasis gas water heaters are used as a back-up for the solar
installation. Water is fed from the solar panels into the heaters
where it is either mixed with cold water to achieve the desired
temperature, or, if the water in the solar panels is not sufficiently
hot, the geyser is automatically ignited, heating the water to the
desired temperature.
“Both the Solasis models come with electronic battery ignition and
don’t require mains power supply. And because there is no pilot light
these models are even more energy efficient than conventional models.
“South Africa’s sun-filled climate is ideally suited to solar heating.
Not only is it much cheaper but it is eco-friendly, conserving fossil
fuel and making for a cleaner atmosphere. With demand for electricity
fast approaching peak generating capacity the solar/gas water heating
solution will become increasingly attractive.”
Both models have the following features:
• Brass hydraulic valve.
• Stainless steel universal burner.
• Electrolytic copper heat exchanger coated in aluminium paint.
• Ionisation safety.
• Electronic battery-powered ignition.
• Hydraulic control.
• LCD display.
• Automatic water flow adjuster.
• Water inlet filter.
• Gas inlet filter.
• Water shortage safety mechanism.
• Vertical outlet non-return draught diverter.
Fagor gas water heaters come in two variants, those that burn LP gas
and those that run on natural gas. Both are available from ADCENG Gas
Equipment.

Solasis Water Heating Schematic
A schematic of a Fagor Solasis solar/gas water heating system, which
in this instance, uses a heat exchanger for maximum efficiency. Water
heated in the solar panels is circulated to the heat exchanger where
it transfers heat to a separate flow system which circulates water
between the heat exchanger and the storage tank. When hot water is
required it is drawn off the storage tank and fed through the gas
water heater which adjusts the water to the desired temperature by
either adding cold water, or, if there has been insufficient solar
energy, by heating the water with the gas burners. |
