It's the new trend in water heating that's fast gaining
momentum in South Africa! Whether in homes or hotels, water heating accounts for a large portion of electricity usage. And with rapidly increasing electricity costs, everyone's looking to cut down.

That's why Sirair Water Heater sales are rocketing!
Sirair Water Heaters work on the same heat-pump
principle as air conditioners, extracting ambient heat from the atmosphere but, instead, transferring it to water. Thus where in a normal geyser, 1 kW of electrical energy produces just 1 kW of heat energy, with a Sirair Heat Pump Water Heater, 1 kW of electrical energy produces approximately 3kW of heat energy. The result is water heated for only approximately one third of the electrical usage of a normal household geyser.

The domestic Sirair units comfortably heat from 100
liters to 500 liters of water, while the largest commercial unit is 77kW, capable of heating 1660 liters/hour. Modularity allows up to 7 sets to be linked, with water temperature adjustable from 40o to 60o. Eco-friendly and cheaper to install than solar heating, Sirair Water Heaters are guaranteed and backed nationwide by Sirair.




How does a Heat Pump work?



Electricity is used in an Sirair Heat Pump simply to power a compressor and a fan. The compressor compresses gas
into a liquid, causing it to heat up (in the same way a bicycle
pump gets hot when a tyre is pumped up). This heat is then transferred to circulating water which is stored in a geyser.
In the next part of the cycle the gas evaporates, resulting in
it cooling down. Here, a fan blows air over the cold gas-flled piping, which extracts 'free' heat from the ambient temperature and causes the gas to warm up again. The gas is then
compressed once more, releasing the extracted heat to
warm water and the cycle continues as before. Result:
energy-effcient water heating at a third of the cost of
electric-element heating.

ADVANTAGES OF SIRAIR HEAT PUMP TECHNOLOGY

Sirair Heat Pumps are eco-friendly, much better than
solar/gas geysers, easily installed, highly energy-efficient
and well-suited to domestic and commercial applications.



The COP (Co-efficient of Performance) of a Heat Pump is
the ratio of change in heat at the ‘output’ side relative to
the supplied work. While the COP is partly a measure of
the efficiency of a Heat Pump, it is also a measure of the
conditions under which it is operating. In other words,
the COP of a Heat Pump will rise as the ambient
temperature increases. In South Africa, where ambient temperatures seldom fall below zero, a Heat
Pump can operate very efficiently, delivering
high COP values.
