Guide to Smart Water Heater Technology

Water is an integral part of our lives. Aside from being a bare necessity for survival, it is perhaps the single most important part of our daily living because we use it for domestic chores such as bathing, cooking, washing, and more. Over time, people have discovered that hot water is more useful compared to lukewarm water, and with that, technology has offered us many options to obtain hot water.  A water softener is widely used to soften hard water. The best quality water softener salt removes the calcium and magnesium ions from water. the type of salt you select can affect the efficiency of your water softening system and the regeneration process.

Up until very recently in human history, water was heated in kettles and pots, however, we are unable to get a continuous supply of hot water at fixed temperatures through this process. To solve this problem, water heaters were invented. They were able to provide us heated water continuously at preset temperatures at any time we want with just a touch of a button.

Water heaters utilize an energy source to be able to heat water until it reaches the programmed temperature level. However, the major flaw of a water heater, either electrical or solar, is it consumes a large amount of energy.

Once hot water is released from the water heater, then more cold water comes in and is constantly being heated. With this, a large amount of energy will be wasted when your taps are turned off.

New water heaters are being designed and upgraded to help reduce the level of energy consumption and reduce the cost of heating water when hot water isn’t currently in use. Some of the solutions invented were tankless water heaters, solar heaters, and electric showers. Today, there is the newest addition to the many types of water heaters which is the Smart Water Heater.
