Tankless heaters for domestic hot water are just as safe as traditional hot water tanks; they simply work differently. Tankless heaters go into action when you turn a hot tap faucet on. They work by drawing cold water into a wall-mounted heating element, instantly heating it to a set temperature, and delivering it to the tap. Your tankless heater uses less energy than a water heater does at keeping a full tank heated. Also, because manufacturers of tankless heaters have improved and refined the technology over the years, they have resolved any safety issues their prototypes may have presented.

On the Other: Potential Safety Concerns

As with any heater, you must regulate the temperature to prevent the possibility of being scalded by overly hot water. Manufacturers recommend that you employ a professional to install a propane or natural gas-powered unit to ensure that the tankless heater is safely and properly vented.

Bottom Line

Tankless heaters are safe, provided that you take a few standard precautions. Learn how to regulate water temperature with your unit, and have it professionally installed according to the manufacturer's specifications.
