Tankless water heaters are today's most popular "green" hot water solution, with the added benefit of actually enhancing the clients' experiences in a luxury bathroom. No matter how many body sprays and showerheads, no matter how deep the whirlpool, your clients will not run out of hot water with a properly sized tankless water heating system.

Tankless gas water heaters are more energy-efficient than conventional tank heaters, because they eliminate the need to maintain a large supply of pre-heated water. Tankless units provide hot water on demand at a precise temperature needed, so there is no storage and therefore no need to expend energy heating that stored water.

About the size of a medicine cabinet, tankless water heaters can easily be wall-mounted indoors and even outdoors, depending on the climate. The ability to place a tankless water heater closer to the point of use solves the problem of a long wait for hot water. That problem is not solved by simply replacing a tank water heater with a tankless water heater in the same place. Delays in hot water delivery have to do with where the water heater is located, not the type of water heater.

Tankless water heaters have convenient digital wall-mounted controls and even waterproof remote controls that make it easy for clients to adjust the temperature as often as they wish for convenience as well as safety. Clients might want exactly 120°F for the dishwasher, but only 106°F for the baby's bath time, and back up to 110°F to fill the tub to precisely the preferred temperature for a relaxing soak.
