The idea behind tankless water heaters is truly a novel one. Instead of continually heating water sitting in a large traditional hot water tank, a tankless system heats the water as it's needed, whether in incremental sessions at a time or one long session all at once.
Tankless water heaters are ideal for both residential and commercial use and we supply them both in natural gas and propane models. They also come in two basic varieties -- point-of-use or whole-house hot water heaters, which determine the quantity and demand of your water heating needs. Point-of-use hot water heaters, which are generally electric, are relatively smaller and are sufficient for separate appliances or households that have single occupants. Whole-house heaters, usually powered by natural gas, are typically larger and ideal for family units or commercial facilities that need to supply water to a number of occupants.
Sitting water, which needs to be continually heated to maintain a constant level of hot water, is how traditional hot water tanks function. The continuous energy needed to maintain this temperature, even when it's not in use, is known as "standby heat loss." Tankless water heater units, or "on demand" water heaters, avoids this by heating the water as you need it. Naturally, this is a concept that can save a lot of wasteful energy, which has the potential to save a lot of money on a monthly and yearly basis.
Tankless water heaters not only save and conserve natural gas, but last about ten years longer than traditional hot water tank heaters, and also don't take up as much space. Other benefits include:
Flow capacity rate varies, but typical tankless hot water heater rates range from about four to ten gallons per minute (GPM). Studio apartments or small single homes would generally use a four to six GPM unit, whereas a residence of at least two or more bathrooms would require a six to eight GPM to service multiple applications at once. Of course, demand is always a factor, and in some residences, more than one unit might be required for optimal sufficiency.
