One of the most popular techniques used in most households in the twenty-first century to save on the electricity bill. The fact that solar hot water systems use renewable energy and works, as well as those that work on grid power, makes them all the more popular. However, there are still several homeowners who have their inhibitions on the installation on the same. So, today, allow reputable solar hot water installers in Mandurah to explain if these systems are worth the cost or not.
What is a Solar Water Heater?
Solar water heaters, unlike what we know of the traditional water heaters don’t use any energy from the grid to heat water. Rather; they use dedicated solar collectors that are to be placed on the rooftop of your house to directly draw power from the sun. The solar energy collected, thus, is used to heat the water. This help cutting down on the electricity bill of your house by heating water using clean energy. Recently, several homeowners have also been noted to use electric heat pumps coupled up with home solar panel systems that run on solar electricity.
How do these systems work?
As you hire solar hot water installers in Mandurah, you will know that these systems can produce enough hot water that fulfils almost all of your regular hot water requirements. Two of the main types of water heaters that run on solar energy include:
- Active Solar Water Heaters: These use a pump to circulate the hot water from the collectors to your home. Typically installed in places where the climate is colder, you can either go for direct or indirect systems, according to your necessities. In case of direct solar water heaters, the water is heated in the collectors itself before being sent to the showerheads or faucets. In the indirect systems, the heat transfer fluid is heated within the collectors before being transferred to the water supply in a closed-loop system.
- Passive Solar Water Heaters: These, instead of circular pumps, rely on the convection as the circulation system. Here, the hotter water rises to the surface as the typically cold water sinks, and the circulation happens. Cheaper than their active counterparts, you can either opt for the integral collector systems or the passive thermosyphon ones. In case of the integral collectors, you get large water storage tanks built into isolated boxed kept on the rooftop. The sunlight directly heats the tanks, and thus, the water is heated. In the passive thermosyphon ones, they use metal flat plate collectors that are responsible for heating small batches of water on the roof itself. As you open them, the hot water flows from the roof to the faucet.
How to select the best solar water heaters for your house?
Each solar water heating system available has its advantages and works best in a particular environment only. To choose the best solar water heater, you need to know a few things such as:
- Direct solar water systems are ideal for places where the temperatures are below freezing.
- Investing in an indirect circulating system would ensure that the fluid can also be redirected to the swimming pool and heat it as well.
- Integral passive systems are ideal for those families who use more warm water during the daylight.
- The thermosyphon water heater is perfect for those who have more roof than ground space.
