Professionals usually recommend that clients looking for new water heaters start to consider a tankless unit. Tankless water heaters offer a number of exceptional features that justify their higher price when compared to typical storage tank water heaters.
Tankless water heaters provide an endless supply of hot water. They consume less energy since they only heat the water when it is required. They are typically smaller than standard tank boilers and can be wall mounted. Tankless heaters have a longer service life.
At first look, tankless water heaters might appear to be a new form of technology, however this is not the case. In 1889, the first commercially available storage tank water heater was produced.
Because of its thick copper construction, it was highly energy efficient, but it was also rather expensive. Tankless water heater development, on the other hand, was not far behind. There were some early and unsuccessful attempts to promote them in the 1890s.
In 1929, Stiebel-Elton developed the first electric tankless water heater, making the equipment more easily accessible. However, gas-powered versions were more efficient and thus gained popularity. However, tankless water heater technology was not effective enough until the 1950s to make them practical replacements to regular water heaters.
Once efficiency increased, Europe started to adopt a greater number of these space- and energy saving appliances. This finally resulted in the introduction of tankless systems into the American market in the 1990s.
They are becoming major competitors with tankless and hybrid heaters, with more and more homeowners realizing their major benefits over traditional tank heaters.
