Water Heaters One Of The Important Inventions

By Nancy Thomas


Tar is a very important ingredient used in road construction. This ensures that the stones and concrete stick together on the road. Typically like a glue used for making roads. This material solidifies in normal temperature so it is important to keep it liquid state. Earlier we used to constantly keep the tar drums on the fire. Drum heaters provide perfect solution against liquid freezing.

Solar water heaters were one of the important inventions in the recent times. In hilly areas it is very difficult to get fuel, dry wood or have power lines. This device helped in solving all the related problems mentioned. They also have the provision for storing heat through thermal collector other than water.

During winters we use the water storage heaters to the maximum. The thermostat keeps the water hot by regulating the temperature. The liquid flows through the inlet and the outlet. In freezing cold we cannot even imagine to take bath in normal water. There is a high risk of storage tank busting if the heating regulator is not working properly.

Instant water heater is tank less. They do not store any water. There is a risk of bursting in the conventional storage heaters if the temperature regulator is not working properly. Also it occupies very large space. On the contrary this device takes very less space. Using the inlet and outlet provides hot water in the same fashion like the former one however there is no risk of bursting as it does not store water.

In the ancient times we used to store fresh water in pots and buckets. There were no shower system or taps as we did not had water flowing with high pressure. In order to create pressure, water has to be stored in certain height. Nowadays we have the storage tanks which are installed at the rooftops allowing the water to flow.

Drinking water is the most important thing for mans survival. People cannot live with salt water which is plentiful in the earth. We are dumping garbage, plastic and other industrial waste in the rivers. This has created shortage of water across the globe. Every living being will be extinct from the planet without fresh water. We must take a step forward to preserve our natural resources.

Heat from the fire or sunlight is very important for the survival of humans. The fire has allowed man to live in cold climate also protected them from wild animals. This invention has also taught man to cook and eat processed food. Always the colder climate areas have lower population compared to the tropical places. During winters we do not get enough sunlight which is not good for health.

Every living being has a temperature. This is because the food that we eat is converted into energy. The body needs heat for performing physical and metabolic activities. There are also living organisms which are usually under sea or ocean has lower temperature. They are known as cold blooded animals. Mammals are under sea creatures which have higher temperature.

The evolution of any species has not caused damage to the environment as that of humans. This is happening because we are depleting the natural resource which in turn is polluting the environment. The industrialization on the other hand is dumping chemical waste into the rivers not leaving any fresh water to drink.
