A tankless water heater in New Jersey -- installation in an attic space.

Compact and efficient: A tankless water heater can be mounted just about anywhere - even in the attic, as shown in the photo. Gas-fired models must have a flue to exhaust combustion products to the outside.

How a Tankless Water Heater Works

No hot water tank is required (thus the "tankless" designation) because the water is heated on the way to its destination. The flow of water triggers gas burners or an electric heating element inside the heating unit.

When the tap is closed, the heat goes off and energy consumption stops. Because a tankless water heater eliminates standby heat loss, you're not paying to continually reheat water in a tank.

This makes any tankless water heater inherently more efficient than any tank-type water heater.

High Efficiency Tankless Water Heater

Dr. Energy Saver is replacing a leaky, gas-fired water heater with an energy efficient tankless water heater. Among the many advantages of tankless water heaters is the fact that you never run out of hot water, because the water is heated on demand.

Tank Or Tankless Water Heater?

Tankless water heaters are used extensively in Europe, where energy costs are much higher than they are here. Case studies have demonstrated that replacing an old tank-type water heater with a tankless model can cut water heating expenses by as much as 45%. Tankless heaters fueled by natural gas and propane are more efficient than electric models.

Energy efficiency isn't the only benefit you enjoy with a tankless water heater. While a tank-type water heater can actually run out of hot water, a tankless model can provide an endless supply, as long as there aren't too many users at one time.

Installing a Tankless Water Heater System

Tankless water heaters are very compact. A house-size model is about the size of a suitcase, and can be mounted on the wall.

Gas-fired models must be vented to the outdoors, but many of these utilize direct-vent technology, which means that no chimney is required.

Instead, exhaust gas is vented outside through a PVC pipe that extends through an exterior wall.

That's right! Tankless water heaters are so good at transferring all the heat from burning fuel to the water, that the exhaust gas is cool- so no heat is wasted up a chimney! That's how it can use plastic pipe to exhaust out the sidewall of your house instead of up a chimney.
