One of the greatest advancements in human habitation was the addition of a self-contained hot water system that supplied the necessary hot water for a home. It has become such an important aspect of modern living that most communities have requirements that each home, regardless of size, is equipped with a safe and adequate hot water heater.
Coming in two different fuel types, gas or electric, they go largely forgotten until they fail or suffer a problem. New tankless models offer more efficiency over the older tank styles and are slowly supplanting the older versions quickly. If you are considering a new hot water heater, a tankless system is the best way to go.
Giving Up The Tank
Prior to the 1990’s, the mass majority of hot water systems were either the boiler style or the tank style system. This allows for a steady supply of ready hot water on demand. However, these models were grossly inefficient in terms of how they heated the water and how much energy they used to accomplish this task. Tankless systems flash heat the water, thereby only using the amount of energy necessary to cause the water to reach a set temperature, typically 120-140 degree F. If you have a forty gallon tank, it takes a certain amount of energy to heat that amount of water to the required temperature.
Tankless systems apply the heat to the pipe which contains less water and thus require less energy to be heated. As new water, which is colder is introduced, it can quickly be brought up to the correct temperature without expending more energy to reach the same temperature as the exiting water. Thus, the whole system is very efficient with some models having a ninety-nine percent efficiency when compared with tank systems. Modern tankless systems have come down and can be used in multiples for larger homes, thus furthering the efficient savings for your home.
