Every place that needs hot water needs a way to heat it. Until recently, there was only one way to do that – by heating and storing water until ready for use. While still the least expensive system to install, there are now compelling alternatives to the traditional heater.
“Tank less” heaters are fast becoming a popular alternative. They do not store hot water, but heat it only as needed and deliver it instantly. Because the cost of storing heated water is a significant part of the monthly power bills of homes and many commercial facilities, tank less water heaters can provide cost savings sufficient to pay for themselves in a few years. But tank less models are not just a greener alternative because they use less power; they also tend to reduce water demand. When there is no need to run the tap for a few minutes to get hot water that reduced water usage is another way to save money and natural resources.
