When many people think of solar water heaters, they think of the system where the solar collectors and tank are put on the roof of the house. In this type of system, the water flows down from the tank to the tap or the shower through gravity. These solar heaters are called non pressurized solar water heaters.
Unlike in the pressurized system where the tank is enclosed, in this type of system the tank is open with exhausts at the top. The exhausts allow escape of steam to maintain desired pressures and temperatures inside the tank. As such, these tanks cannot be installed inside the house. They are usually installed on the roof tops together with the solar collectors.
Non pressurized solar water heaters are also more efficient in terms of energy use and they have a long life. This is because the system is not under high pressure which can cause parts of the system to fail. The water temperature at the output is first low initially because of the water that remains in the pipes. However, as the water flows the hot water from the tank reaches the output at desired temperatures.
A solar water heater is an investment and therefore should be taken seriously. To ensure your investment in a non pressurized solar water heater, ensure that you get a reputable company to work with. As a leading solar installer and supplier, you can rest assured that you will get a water heater that is right for your needs.
Besides, we also have expert solar technicians who do the installation, monitoring and maintenance of your system. We go beyond just installing the system and leaving it to you. We monitor to ensure you are getting the best from the system and can optimize the position of the collectors if need be. However, since we conduct site visits to determine the best installation position, we always get it right the first time. Contact us today to learn more.
