A General Overview Of The Solar Hot Water System Installation Process

by April Rivera

How are solar water heater systems installed? While the exact steps followed during solar hot water system installation may vary from contractor to contractor, there are basic steps that any installer will likely follow. The following guide is meant to provide a rundown on the solar water heater installation process. 

Mounting of the solar collectors.

This is the first step of the solar water heater installation process. There are different mounting options for solar collectors, including roof-mount, ground-mount, and wall mount. A lot of factors are considered in determining the appropriate solar collector mounting option for each home. Some of the most important considerations include: 

  • The optimum solar panel orientation.
  • The safety and protection of the solar panel installation.
  • The condition of the existing roof and the maximum structural load it can support.
  • The proximity to the solar pump station.
  • The esthetic of the solar panel installation.
  • Ease of assembly of the collectors.
  • Ease of access to collectors for repair and maintenance purposes.

Generally, roof mounts are favored over other options because they use the existing roof, and therefore, don't take up any more space. Ground mounts will take up some of your yard space but they're easier to access for assembly and servicing. Plus, they give you greater control over the orientation of your collectors to maximize production. Wall mounts provide a great angle if you're looking to make the most out of your solar hot water system during the winter.  

Installing the storage tanks and the heat exchangers.

Once your collectors have been mounted, the next step is to install your hot water storage tank and the heat exchanger located inside it. Heat exchangers are made of metal material with excellent thermal performance. These include copper, bronze, aluminum, stainless steel, and more. They use a heat-transfer fluid to transfer solar energy absorbed in solar collectors to the water stored inside the tank, providing households with hot water supply, You can install as many storage tanks as you want, depending on your domestic hot water demand.

Installing the piping and control systems.

The last step of the solar water heater installation process involves installing the various piping systems that will be used to circulate heat-transfer fluid within the water heating system, as well as deliver water to various faucets and water fixtures in the home. Temperature and pressure controls for the water heater will then be installed and connected with wiring along with the rest of the hot water system.
