The use of Tank-less Hot Water Heaters

Tank-less, or on-demand, Hot Water Heaters have been popular in Europe and Japan for years. And they are starting to attract more attention in North America. Tank-less heaters are small wall-mounted units that can be fueled by gas or electricity, producing hot water only on demand. When a hot water faucet is turned on, cold water begins to flow through heated coils on the unit heating the water to the preset temperature you chose.

When they were first introduced many years ago, very few builders or homeowners were interested as a result of their relatively high price and potential reliability issues. However, with the ongoing rise of fuel costs and the better redesign of these units to eliminate reliability issues, a renewed interest has been seen in new construction.  The primary benefits advertized are their energy efficiency, limited space requirements, and ability to supply hot water whenever needed.

And although these units will supply hot water on demand, they were not originally designed for high water volume output. On average, tank-less heaters provide sufficient hot water at a normal water flow rates.  But, if there is a demand for hot water from many different sources at one time, a tankless heater may not be able to keep up.  The higher volume may result in lower supply temperatures during higher demands. 

These units can provide utility cost savings; but when considering installing one of these units, homeowners must look at all the costs and benefits versus storage tank type units. Always review explicit manufacturer information and understand that at least in the beginning switching to a tank-less heater might require some adjustments in your hot water usage patterns.
