how it works in 3-steps

  • assembly

    Step 1: Assemble your GravityFlow system which is shipped to you as a flat-packed kit using our assembly guide and video (under development!). We have worked hard to make the assembly process as easy as possible.

  • Fill with water

    Step 2: Once assembled and placed somewhere sunny, the next step is to fill the system with water. The water storage tank is located at the top and can be filled using a hose or bucket.

  • The solar heating starts!

    After the system is filled with water all you need to do now is leave the system in the sun. The heating process is fully automatic so you don’t need to do anything. The water tank will be slowly heated using just sunlight.

FAQs

  • We have designed GravityFlow to be as simple as possible to assemble. You don’t even need a screwdriver to assemble it! We recommend taking your time and following our step-by-step assembly video during assembly.

  • The temperature which GravityFlow heats water too will depend on how sunny it is and air temperature, but it can heat water up to 50 degrees Celsius in good sunny conditions.

  • GravityFlow will heat a maximum of 25 litres of hot water.

  • You won’t need to connect GravityFlow to mains pressure piping which makes it much easier to install. To fill the system, simply use a hose or bucket and fill the system with clean, fresh water.
