Heat Pump Water Heaters

The table below highlights the efficiency of Alliance Heat Pump Water Heaters as compared with other types of water heating e.g. gas,

electric element, diesel oil and solar. Alliance Heat Pumps are eco-friendly, easily installed, highly energy-efficient and well-suited to

domestic and commercial applications.

ADVANTAGES OF ALLIANCE HEAT PUMP TECHNOLOGY

Scientific tests have shown that, where in a normal electric geyser, one unit of electrical energy produces one unit

of heat energy, with a Heat Pump, one unit of electrical energy produces between 2.5 and 3.5 units of heat energy.

THAT’S WHY USING AN ALLIANCE HEAT PUMP TO HEAT YOUR GEYSER CAN CUT WATER HEATING COSTS

BY UP TO TWO-THIRDS!

How does an Alliance Heat Pump work?

Electricity is used in an Alliance 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-filled 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-efficient water

heating at a third of the cost of electric-element heating.

Commercial Installation

Due to the modularity of Alliance Heat Pump Water Heaters, as many as 16 units can be linked together to supply up to ten thousand

litres of hot water per hour. Water temperature as well as heating periods can be adjusted via remote control to meet specific hot water

demands. These factors, along with major savings in electricity costs, make Alliance units well-suited for commercial use.

MODULARITY ALLOWS CAPACITY INCREASE
