Solar water heater is a heating device which converts solar energy into heat energy. It heats water from low temperature to high temperature to satisfy people's use of hot water in life and production. Because of the long-term natural climate, failure is inevitable. As a kind of solar water heater, the non-pressure solar water heater is inevitable. So what are the common failures of this solar water heater? How is it repaired? Below is a brief analysis of the troubleshooting of the non-pressure solar water heater . I hope this article can give you a better understanding of the pressure-free solar water heaters .

Solar energy is the main source of energy for our planet, because it is responsible for providing energy for plant growth and warmth to make our planet habitable. Solar water heaters use solar energy to generate heat and then heat water for showers, space heating, industrial processes, and even solar cooling. So solar water heaters are one of the most effective ways to reduce household carbon footprint by reducing dependence on dirty fossil fuels. By offsetting the use of electricity, natural gas or heating oil, the use of solar water heaters can also save money by reducing energy costs. There are many kinds of solar water heaters, according to water pressure, there are pressure-bearing solar water heaters and non-pressure solar water heaters. Then, how to correctly select the pressurized solar water heater and the non-pressure solar water heater , the following makes a brief analysis of this.

Today, the global energy situation is tense and the climate warming seriously threatens the economic development and people's health. All countries in the world are seeking new energy substitution strategies in order to achieve sustainable development and gain a dominant position in future development. Solar energy has become the focus of attention because of its clear, continuous and safe advantages. Therefore, the emergence of solar water heaters is undoubtedly a great invention for people. There are many kinds of solar water heaters, which can be divided into pressure solar water heater and non-pressure solar water heater . This paper makes some analysis on the performance of pressure solar water heater and non-pressure solar water heater.
