Hot water accounts for almost 50-60% of your electricity consumption so its a great place to start saving.
We provide two economical hot water solutions to choose from:
Solar Hot Water
Solar Geyser are an alternative to gas or electricity powered geysers. Averaged over a year, a correctly sized Solar Geyser indirect System can provide 80% to 100% of a household's hot water needs. The hot water system can easily be augmented with the natural gas boosted or electric geyser so hot water is guaranteed regardless of sunlight levels.
What if it's an overcast or rainy day? Although the heat output of the solar collector is reduced on overcast days it will still be able to provide heating. If it is a heavily clouded day or raining, then more gas or electric boosting may be required to maintain water at the required temperature.
What size system do I need? Generally bigger is better with solar. A good rule is 75L of water person living in the property, 4 people x 75 litres = a minimum of a a 300L Solar Geyser system. If the system is under sized then you will run out of hot water or use excessive electrical boost heating.
A traditional element geyser uses three units of electrical energy to produce three units of heat energy, a heat pump converts just one unit of electrical energy into three units of heat energy - hence a saving of up to 75%. A 5kW heat pump will heat the water slightly faster than a 4kW electrical element typically found in 200L geysers. The heat pump produces 5kW of thermal energy under specified conditions while using as little as 1.2kW to do so.
The main advantages of a heat pump are the ability to re-heat a geyser a few times per day and that it can work day and night, rain or shine. A solar system will only save you more money if its capacity exceeded its demand which is highly dependent on the usage pattern.
Our heat pumps range requires virtually no maintenance of the system except for making sure the evaporator is clean from dirt and leaves. We do however recommend that the system be checked annually to ensure that you are getting the best possible efficiency out of the system.
We have a range of heatpumps suitable for domestic and commercial uses. We also install pool heatpumps.
So how does it work? Heat pumps use the reverse cycle of a refrigeration plant to heat water. In effect, it transfers heat from a source such as air to the water which is to be heated. As in other refrigeration equipment, the heat pump system employs an evaporator, a compressor, a condenser, refrigerant gas, and an expansion valve within a closed circuit.
Latent heat is given off when the refrigerant gas is liquefied through the condenser and transferred to the surrounding water together with further “sensible” heat loss, effectively raising the temperature of water to a higher temperature.
