    Another Benefit: 2 Geyser = 2 Elements
    You can change the "cold" geysers element to a 1.5KW element, and link it onto your inverter, and control it with a Relay from your BMV/Charger.  When your BMV gets to 100% or your charger goes to Float it switches on..  Result - You dump your excess electricity generation in your geyser. Still having the second "warm" geyser on Eskom.

    I also received a nasty letter from CoCT a month ago for my wife's dental practise (Trading from Residentially zone property). 
    2 Weeks ago I linked the toilet (8lt) of the dental practise (3 staff) and the toilet (13lt) from accounting firm (5 staff) next door up to a wellpoint.  I put a water meter in because I like stats.  Got a fright of my life after the first week.  On average 250lt being used per day just to flush the 2 toilets!  Saving 5kl per month!

    My brother installed 2 x 200l Geyser in Series. Both have their own 20 EV Tubes connected to it running from 2 Geyserwise. 
    Works perfect.  The water entering the second geyser is already warmer so it does heat quicker by EV or element. You also don't need 400lt at 55C, Only 200lt at 55C. Reducing heat loss.
    Benefit of 2 geyser is that you can set different temps and can change them through the year. ie. In summer you drop the first geyser's element setting to 30C (i.e Does not come on), in winter to 45C. You can also change it if you are having people stay over and you need 400lt at 55C. Back to 200lt at 55C when they leave.

    But there is a chance that the stuffed up the wording and that it will only apply to properties below R400k

    @superdiy You may want to look into installing a pressure tank.  It reduces the amount of time your pump needs to kick in
    Picked up a 24lt tank from Brights for R660 - Result is that my 1.1Kw pump only kicks in every 2nd time the toilet is flushed.  The 1st time it runs from the pressure tank.
    It has an added benefit for me. I have around 70m of pipe that are pressurised running to 3 points on my property where my 8 irrigation taps and 3 extra manual taps are. With a small amount of leakage on the pipe/connectors/taps the pump would kick in every 15minutes to pressurise the pipe. With the pressure tank it has stopped doing it.

    Connected 1 toilet in my house to the pressure pump of the borehole about 6 weeks ago. I was lucky: My outside tap was connected together with the toilet after the toilet stop tap (i.e when you close the toilet tap, the outside tap does not work). So closed the toilet tap, removed the outside tap and connected the water to it. No further plumbing required.
    Previously we used around 350l/day between 2 people. This has dropped to around 250l/day between 2 people.
    It is scary on the amount of water is being used by flushing a toilet 10 times a day.

    This looks line a similar product than the one where you bought shipping containers a few years back.  In the end the only one making money is the person managing the investment.
    The documents available on their website are more marketing documents that actual information. My questions:
    So I buy the panel today, do I pay for it today? If so will i get interest on my money until the project is actually installed (When 70% of the panels are sold)?  
    What management fee with FedGroup earn for doing the "work"?
    How will my income be calculated? The claim 9% return in the first month? How was this calculated. And when is month 1 (Next month or in 6-12 months time when the installation is completed)
    Who guarantees the R1,000 buy back (Agree with PaulF007 - Actually nothing in today's terms)
    In the end a nice idea but I would rather spend the money on 2 more panels on my roof.

    I run a wellpoint at my Wife's practise. Luckily it is low lying so the water last most of the Summer. Getting around 1,300 lt per hour at 2.5m depth.  In April it started struggling after 45 minutes usage, but luckily my controller allows 3 starting times. So I water half of the garden the one day (40min) with the other half the next day (30min).
    Wellpoint cost: R1,500 (Had a pump already)
    Water saving in first year: 250kl 
    Payback time is calculated in hours!

    @Mark With my research I have come to the conclusion that you should not look at average wind speed The amount of energy that you can generate as 6km/h is more than double what you can generate at 3km/h. If you look at graphs of windspeed against power it is not a straight line
    1km/h + 9km/h = 5km/h average
    4km/h + 6km/h = 5km/h average
    According to my knowledge the first example generate more power than the second one

    The big trick for using grey water is that you DON'T want it to stand. It becomes smelly very quickly.
    My shower, washing machine and bathroom basins flow into a 100l tank. You could even get away with a 50l tank (No need to dig a big hole) Then I have this:
    http://www.dabpumps.co.za/web_network/southafrica/en/page_471.php?serie=352&linea=68&language=en&minisito=13
    It is linked to an ordinary garden hose with a "Skilpad spuitjie" at the end. It switches on and off by itself based on the water level in the tank.  In summer we move it once a day, rotating it through a section of the garden over 3 days.  I have disconnected the automatic sprinklers from this section of the garden.
    PS - Make sure you are aware when somebody is in the shower or the wife is doing laundry.....

    Louw got a reaction from Chris Hobson in Solar retrofit   
    I installed a 20 tube collector on a 250l geyser. 
    I use a Geyserwise Max to control a 12v pump to circulate the water. I decided against a 220v pump due to issue when there is loadshedding (If you lose power for 30minutes in the morning your collector can reach 100C plus, which cause the safety feature to kick in. It means that the pump will not circulate the water till then next day after the collector has cooled during the night when the power domes on agaiin. This is to avoid 100c water being pumped through the pipe). I have a 10w solar panel powering the pump with a 8ah battery as backup.
    I am very happy with the performance of the system.
    I did not use the retofit kit for a Kwikot geyser. I just made a cut in the warm and cold water pipe before/after the geyser (all after the prsure valvue) and installed a T junction in the pipe that goes to/from the collector.  So the water goes from the warm water side, through a tap/one way valve, to the pump, collector, another one way valve, and then back into the cold side of they geyser (about 6C warmer)
    The most difficult thing (excluding movIng my 1.95m/105kg frame through the roof) was drilling holes through the roof tiles. (Start with small drill and then going bigger with no hammer action)
    I bought most of my parts online at plumblink, which are about 15% cheaper than buying it at the store.
    Use copper pipes as they can handle high temps.

    I finished my DIY solar geyser conversion 2 weeks ago. Total cost was just under R12k. Collector is the biggest part of the expense but the smaller parts quickly add up (Geyserwise, pump, copper pipe and fittings). 
    Was running on 4kw per day for heating the geyser. After the installation was done it dropped to an average of .5kw for the first 10 days
