A non-pressure solar water heater is a type of solar water heating system that operates without the use of a pressure storage tank. Unlike traditional solar water heaters, which rely on pressure to deliver hot water, non-pressure systems use natural convection to circulate water through the system.

In a non-pressure solar water heater, cold water is supplied to a flat plate or evacuated tube collector, which absorbs sunlight and heats the water. As the water heats up, it becomes less dense and rises naturally through the system, allowing cooler water to take its place. This process, known as thermosiphon, creates a continuous circulation of water, with hot water rising to the top and cold water sinking to the bottom.

The heated water is then stored in a non-pressurized storage tank located above the collector. Since there is no pressure in the tank, it doesn't require additional safety measures such as pressure relief valves or expansion tanks.

Non-pressure solar water heaters are often used in areas with low water pressure or in situations where a simple and cost-effective solar water heating solution is desired. They are relatively easy to install and maintain, and their efficiency can be improved by insulating the storage tank and pipes to minimize heat loss.

It's important to note that non-pressure solar water heaters are not suitable for high-demand applications or areas with extremely cold climates, as they may not provide sufficient hot water or freeze protection. In such cases, pressurized solar water heating systems or other alternative options may be more appropriate.

The comparsion between Pre-heated Pressure Solar heater and Integrated Pressure Solar heater

 


Who will be the winner ?
Pre-heated Solar Heater or Heat pipe Pressurized Solar Heater ?
Discuss it ! info@useesolar.com



Have you faced such problems from the Coil type Pre-heated Pressure system ?



Hi 

The tank problems were

1 corrosion at welded connections

2 cracks due to thin metal caused by heating and cooling cycles

3 copper coil failure due to poor support design ( movement of coil on  square support rail causing hole )

4 corrosion of short tubes that connect assistant tank , vent , and drain


Say something about your thoughts of solar water heater


The main difference between a pre-heated pressure solar heater and a compact pressure solar heater lies in the way they heat the water and their overall design.

Pre-Heated Pressure Solar Heater:
A pre-heated pressure solar heater, also known as an indirect solar water heater, operates by using two separate water circuits. The first circuit consists of a solar collector that heats a heat transfer fluid (usually a non-freezing liquid like antifreeze), which is then passed through a heat exchanger. The heat exchanger transfers the heat from the fluid to the water in the storage tank, thus indirectly heating the water. The heated water is stored in a separate insulated tank and is pressurized for distribution throughout the building. In this system, the potable water (water for everyday use) does not directly flow through the solar collector.

Compact Pressure Solar Heater:
A compact pressure solar heater, also known as a direct solar water heater, operates by directly circulating the potable water through the solar collector. The collector absorbs solar energy and heats the water as it passes through the system. The heated water is then stored in an insulated tank and is pressurized for use in the building. In this system, there is no separate heat exchanger or heat transfer fluid; the water itself is heated directly.

In summary, the key differences are:

Pre-heated pressure solar heater uses a separate circuit with a heat exchanger to transfer heat from a heat transfer fluid to the water, while compact pressure solar heater directly circulates the water through the collector for heating.
Pre-heated pressure solar heater indirectly heats the water, while compact pressure solar heater directly heats the water.
Pre-heated pressure solar heater requires a heat transfer fluid, while compact pressure solar heater does not.
The design of the two systems may also differ, with pre-heated pressure solar heaters often requiring additional components like a heat exchanger and separate storage tank, whereas compact pressure solar heaters can have a more integrated and simplified design.
The choice between the two types depends on factors such as local climate, water quality, and specific user requirements.
