Diy solar geyser

Investing in a solar geyser is like putting money in the bank. But what if you already have a tank that works perfectly? Do you really need to get a new one just to switch to solar power? Not if you decide to go with the 150L ITS Flat Plate 220v retrofit diy solar geyser conversion kit. With this kit you can use the tank that’s currently installed and still be able to save up to 90% of water heating costs.

You get the high quality collector, a circulation pump to circulate the heat between the collector and the tank, a tempering valve and two leaver ball valves. You’ll also be getting a Geyserwise controller, which gives you more out of your solar geyser system, acting as the brain of the whole operation. You’ll never be disappointed if you invest in a retrofit geyser kit.


DIY Instructions:

We have added a DIY manual for you to do the installation yourself if you wish. You simply need to be handy with the hands and make sure you follow the requirements for the warranty to remain intact.

Simply follow the instruction in the manual below:


How solar water heating works:


Geyser: You will need a high pressure electric geyser (400kp or more)

Roof: A 25 – 45 degree pitched, predominately north / south facing roof.


We have structured this kit based on the average home owners electric geyser setup. A new geyser installed within the last 4 years will have the right pressure control.

Geysers were on lower pressure before that date and usually are not compatible with this conversion.

Things to check:

  1. What size geyser do you have?
  2. What is the pressure of the geyser (marked by kpa)
  3. Which direction does your roof face?
