Solar Water Heater

A solar water heater is a device that captures sunlight to heat water. It can be an economical way to generate hot water for your family for shower and bath.

Solar water heater not only enables substantial energy savings as solar power is free in contrast to natural gas or fuel oil. Moreover, it is a way to produce hot water for sanitary use throughout the year without emitting any CO2. 

The system installed on a terrace or open space where it can get sunlight and the energy from the sun is then used to heat water and store it in an insulated tank. The system is not connected to electricity supply and thus does not have an on-off switch, but it uses the sunlight throughout the day to heat the water and store it in the storage tank. 

Most of the solar water heater on a sunny day can provide heater water at about 68° ±5° C temperature. Water from the storage tank can then be used for any application as desired.

When there is insufficient sunlight, the water is preheated and a back-up system takes over to bring the water to the required temperature. This system can be used at a constant temperature throughout the year.


How we work

  • 1. Mounting solar collectors on the roof

    The first step that you need to follow for installing a solar water heater at home is to mount solar collectors on the roof.  It is important not to make many roof penetrations during this process.

  • 2. Install storage tank

    The next step to follow is to install the storage tank. For this, we need to first place the solar storage tank near the conventional water heater.

  • 3. Install the piping and pump

    Now the next step for installing a solar water heater is to install the piping and the pump.  For this first, we need to assemble the entire glycol loop without the solder and solder the entire loop.

  • 4. Install the controls

    After this, we must install the controls. The differential controller must be installed so as the sense the temperature difference between the glycol at the top and the water at the bottom of the solar storage tank.

  • 5. Insulate water and glycol lines

    The final and last step is to insulate water and the glycol lines. This can be done by using standard foam pipe insulation.  Duct tape can be used for all the joints.
