Being blessed with more sunlight than we can ever hope to use up here in South Africa, coupled with our looming energy crisis, electricity-rations and the rising cost of municipal bills, there is no better time than NOW to invest in a solar geyser. New technology Evacuated Glass Tubes (EGT) have resulted in a revolutionary paradigm-jump from the older types of solar geysers (that used the heat of the sun only), to the new EGT-type that utilizes sunlight in infrared- and ultra-violet rays, to provide a 95%+ effective unit. In fact, it is so effective that you can literally make coffee/tea from the water in the tank (if you wish), since it can reach up to 100° C on a normal sunny day! (Typical Pretoria area between 12 noon and 4pm) Sunlight-driven glass tubes mean that the geyser is effective even in our winters and also on rainy/cloudy days. A unit tested in Midrand, SA, still produced warm water after one week of constant rain and heavy cloud (measured in January 2008). In other words: the water entering your old electrical geyser now, is much warmer than before (min ~40° C/max ~100° C) and the thermostat-heater doesn’t have to switch on as much as before. Provided the solar geyser is installed in series with your existing household geyser (and therefore acts as pre-heater) this means that you start saving money right from day one, even while you are still paying for the installation of it! General savings for solar geysers are in the order of 40 – 50% of your electricity bill or around R 500-00 per month for the average SA household, resulting in the unit paying for itself in about 18 months. Like it or not, you will eventually be forced to install solar heating at one time or another, either by legislation (because of power shortages) or out of necessity (because of rising power costs), so, the sooner the better for you and for your household.  

Features of our type of Solar geyser:

  • Utilizes both infrared- and UV-rays from the sun (much more effective)
  • Metal parts all powder-coated stainless steel
  • Lifetime expectancy on all parts = 20yrs.+
  • Geyser ISO 9001-9002 quality approved (no need for SABS rating)
  • 50mm Polyfoam insulated tank – no heat loss overnight
  • Modular frame suits flat/pitch roof of any angle
  • EGT tubes guarenteed up to 25mm hail resistance
  • Unit tested to -35° C without freezing up
  • Safe, low-pressure designed system – works BOTH in ‘stand-alone’ or ‘teed’ into existing geyser, modes!
  • Absolutely no electricity needed – heater element purely optional extra
  • Water circulated by natural process of convection (hot water rises/cold water sinks)
  • Highly effective Borosilicate tubes literally boil water in tank to 100° C
  • Direct heating of water – no intermediary/"anti-freeze" liquid necessary
  • No pumps, no maintenance, hassle-free, fit-and-forget product
  • Safe, durable, affordable, quality, environmentally-friendly and "green" product

 

 

Modes of installation:

1.  Stand-alone

This Solar Geyser can be solely used in a stand-alone configuration (no electricity, no ESCOM geyser involved). This is: (a) the typical application where there is no ESCOM power available and/or the property is very remotely situated in bush or desert area, but with a lot of sunshine, or (b) where new houses (or additions to existing homes) are built and the property owners are not interested in electrical geysers or forced by legislation (and/or high costs) to go the Solar route… Geysers can be filled from either municipal water-feed, stand-tank (typical game-farm, remote plot or low-cost, "bundu" applications), with a hosepipe, from a borehole, river or dam or any similar supply. The hot water outlet will then go, via tap, into a bath, basin, bucket etc. or into the building’s existing plumbing system, if it has one.

 

2.  Stand-alone, with electrical backup

A similar configuration as in 1, above, but with an added electrical heater-thermostat element as backup in case of prolonged bad weather (2 or more days of constant, thick cloud and rain) This installation is valid where an ESCOM electricity-supply is available, but no other electrical geysers exist. The Solar Geyser will then, in effect, be a 2-in-1 system with a solar part, backed-up by an electrical one…

 

3.  Teed in series with an ESCOM geyser

The preferred method of installation (where a working ESCOM geyser already exists) is to tee the Solar Geyser in series with the existing electrical geyser (Solar Geyser as pre-heater; ESCOM geyser as backup) The hot water outlet will then go, via a valve, into the "old" ESCOM geyser. This has the effect that the water now entering the "old" geyser, is much warmer than before and the thermostat of the "old" geyser won’t switch on as much as before, resulting in $aving$ for you! Should there be a case of prolonged bad weather (2 or more days of constant, thick cloud and rain), then your ESCOM geyser will simply heat the warm water (from the Solar unit) to the required heat setting on it’s thermostat.
