Individuals looking for ways to improve their home’s energy-efficiency
often consider switching to a tankless water heater. If you’re thinking
about hiring a plumber for
tankless water heater installation or repair, then you may benefit from knowing more about how these appliances work.
How Traditional Water Heaters Function
Traditional home water heaters work by filling a tank with water and raising
it to a set temperature. As hot water is used, the tank refills and is
brought back up to the programmed temperature. This means that if the
hot water gets used up, warm and then cold water will start flowing from
your hot water tap. Also, these water heaters continually use energy to
keep the water at a constant temperature, even while your family sleeps
or is out of the house for the day.
How Tankless Water Heaters Function
Unlike their traditional counterparts, tankless water heaters heat water
only as it’s demanded. Because of this, these appliances are sometimes
referred to as on-demand water heaters. It’s this characteristic
of having no standby heat loss—referring to a traditional heater’s
need to continually warm even an unused hot water supply—that makes
tankless hot water heaters an energy-efficient option.
How Tankless Water Heaters Work
To provide hot water on demand, tankless water heaters use a powerful heat
exchanger that transfers either gas or electric-powered heat to the water
as it heads toward the faucet. When you turn on your hot water tap or
adjust your shower head to supply hot water, the exchanger is activated.
Water circulates through it, heats up, and is then delivered. Tankless
water heaters can come in a single, large unit that provides hot water
for an entire house, or in a point-of-use variety, which heats water for
only one or two faucets.
Getting stuck without hot water can be a serious nuisance. If you
