Solar water heaters are becoming a great way to heat steel buildings

Solar water heaters are of three types: one of them is known as the flat-plate collector. This type of water heater is insulated and has weatherproofed boxes, which have a dark absorber put under one sheet of glass or a plastic cover. It is conventionally employed to do solar pool heating. It is made of polymer or metal. There is then, a second type known as batch systems or ICS and they consist of one or more tanks or tubes in black color which are basically insulated and contain a glazed box.

Almost all solar water heating systems contain storage tanks and collectors.

There are two types of solar heating systems for heating water: these are the working (active) and dormant (passive) systems. The active system consists of circulating pumps, which controls the system, whereas the passive system has not got any such mechanism.

The active solar water heating system comprises of two types: direct and indirect systems for circulation. The previous one is helpful in climates and weather where it freezes rarely while the other is effective in places inclined to freezing temperatures, like cold countries. But, in the long term, the passive water heating system is less expensive, lasts for a longer period of time, and requires low maintenance but then, contrary to the active system, it is usually not so efficient.

Solar water heating systems normally have a back-up system for the solar energy, which makes it a usable item during the reduced solar energy and also, during increased demand. It is also effective in times of cloudy days.

As they are eco-friendly, they do not cause pollution and contribute to the cause of environment. It has its set of disadvantages too which are nothing when compared to its benefits. It’s getting popular due to the awareness of people nowadays. Secondly, a large number of manufacturers seeing as a hot business venture, are stepping in to create a tough competition, thus bind them to provide solar water heater in much reasonable price.

It just requires the primary costing of installing it with no further or hidden costs for its usage. It just requires some minimal equipment like a tank for storage; thermal panels absorb heat and pipelines attached to them.
