Hot Water Conclusion

Hot Water Conclusion

and finally my conclusion…  This architect’s conclusion for conditions in South Africa is that a combination of systems seems to be the most sustainable option. My personal preference, layout and budget permissible, is for a high pressure, evacuated tube, solar system...
Electric Water Heating

Electric Water Heating

Yes really…still   While electrical resistance heating can no longer provide the bulk of your hot water it can be used to supplement supply in areas that are not used often, or where smaller quantities of water are used or in the South African Context where you...
Gas Geysers

Gas Geysers

GAS Why gas? To avoid warm water growing stuff in it, it needs to be kept at a minimum temperature of 55 degrees, which is why geysers use so much energy. A gas geyser does away with the need for a storage tank as water is heated instantaneously when it is required....
Heat Pumps

Heat Pumps

An explanation Heat pumps work in a similar way to an indirect solar system in that they heat glycol that heats more efficiently and that heats the water. A heat pump uses heat from the atmosphere combined with electricity to heat the brine, similar to the way an...
Solar Water Heating

Solar Water Heating

This architects summary on solar How does it work? In short, heat is collected by means of liquid being pumped through panels (collectors) that are exposed to sunlight or UV. Heated water is stored in an insulated tank for use. Most tanks have a ‘booster’ or electric...
Hot Water Conclusion

In Hot Water

Water heating in line with 2011 energy efficiency regulations With the advent of the new SANS10400 XA energy efficiency regulation is 2011, the sole use of electrical geysers to produce all your hot water requirements has become illegal. The regulation states that 50%...
