Solar heaters use the energy from the sun to enable homes to have access to hot water. In order to install them and make use of them, you first have to understand the different types available in the market and get enlightened about their pros and cons. In this article, I will be discussing the two types of solar water heating systems.

There has been a high demand for hot water in homes and a lot of energy has been used in achieving that but due to the hazardous effects of unclean energies such as global warming solar energy has been now discovered as the solution and is the highly recommended source of energy and it is already being used in water heating systems. In this article am going to discuss types of solar water heating systems which are mainly two, as follows.

1. Non-Pressurized solar system

Also known as straight in all glass tube vacuum solar water heaters since the vacuum collector and water tank are sealed by sealing rubber ring cannot resist pressure. It uses low-pressure water shutdown, attaining high efficacy and durability.

In this type of system, the water tank has to be placed on the roof or on a raised structure so as to enable water once heated by the sun to flow effortlessly at low gravity.

Advantages

  • Since there is no pressure on tanks and the tubes they last very long.
  • Capable of providing hot water without additional forces such as pumps.
  • They are energy effective as the amount of energy used in these systems is very minimal.
  • It is usually a simple structure thus pocket-friendly both in terms of purchasing price and maintenance cost.

Disadvantages

  • It is a must to install it on the roof or raised structure which might be a challenge sometimes.
  • It is quite annoying when used in showers without pumps due to lack of pressure.

2. Pressurized solar system

As opposed to the non-pressure model that uses low pressure which is the gravity of water, the pressurized model is characterized by the high pressure of water in the tanks which is enabled due to the absence of liquid in the vacuum tubes making it pressure resistant. This system is composed of a phase change heat pipe, heat transfer aluminum wing, and vacuum tube.

Advantages

  • It is easy to adapt to and use since the water temperatures in the confined type are first high and then low in the course of use.
  • Water pressure is very high offering good showers
  • Unlike the non-pressurized system that the collector tanks have to be placed on the roof, for the pressurized solar water heater you can place it in the most suitable places.
  • Have high compatibility with installed pumps

Disadvantages

  • They are more expensive to purchase than the low-pressure solar system.
  • Theyhave highermaintenance cost since they are not as energy-efficient as the non-pressurized one.

Conclusion

As laid out above there are two types of solar water heating systems that is the pressurized and non-pressurized and they both have their advantages and disadvantages, and they differ in the above-discussed ways,so when you want to acquire one look closely at their pros and cons and choose one that meets your needs.
