Solar water heaters, because they are powered by the heat of the sun, are apparently situated on areas direct to the sunlight such as the rooftop. This is to give them enough energy from the sun that would make how water generation possible. From the term “solar-powered”, it is evident that they get their energy from the sun. Aside from being eco-friendly and highly efficient, this home appliance could offer you a low invoice for you water heating procedures as this do not utilise expensive fuel and energy such as electricity. But it would be impossible for this appliance to work without its primary components. Knowing them would help you know your appliance better in case of water heater troubles.
Here are the ten primary components of a solar water heater.
Because solar water heaters are generated and empowered by solar energy, it is necessary for them to accumulate a vast amount of sunlight to make water heating possible. Solar collectors basically spotted and situated on roofs and areas direct to the sunlight, would gather and accumulate the heat emitted by the sun.
Heat exchanger is connected to the solar connector by a pipe loop. They are usually located within the hot water storage and they perform the water heating process. They transform the accumulated sunlight into a solar energy which would be used in heating the water. They should contain anti-freeze to avoid them from losing the gathered sunlight, especially on countries with cold seasons with temperatures dropping below zero degrees.
Hot water storage tank
Hot water storage tank stores the heater water to be used subsequently. They will be provided with cold water and the heat exchanger within it will heat the water. They simultaneously heat water to provide hot water for domestic use. Hot water storage tanks vary in sizes and each of them can contain a diverse amount of water.
Temperature sensors communicate with the solar collector and monitor the temperature within the system, from the heated water to the solar collectors. This is to make sure that the water is heated according to the desired temperature level, not making it too hot or too cold.
Solar controller module
Solar controller module controls the circulation of water into the system. When the solar collectors have gathered enough energy from the sun, the solar controller module would permit water circulation and not if otherwise. This is to guarantee the household that their water is heated rather than cooling them when the energy is not sufficient.
Circulation pump allows circulation of water within the system yet this is controlled by the solar controller module whether to allow circulation or not. No circulation would likely take place when the energy isn’t enough to heat the water.
Expansion tank secures the system and avoids explosion by getting rid of too much pressure. It absorbs the pressure inside the system to ensure its security.
Air vent valve
This component secures the piping not to be air bound. Its primary responsibility is to exterminate undesirable amount of air in the circulation loop.
Pressure and temperature relief valve
Pressure and temperature relief valve should be stationed in every water heater to secure your home and your system. This releases the pressure within the system as it increases to avoid explosion. This should perform its job as quickly as expected to avoid risking your property.
Tempering valve or Mixing valve
Mixing valve mixes cold water with the outgoing hot water. This is to secure the wellbeing of your piping system. Hot water, when not mixed with cold water, might be hot enough to burn your pipes, bathtubs, showers and sinks.
