Tankless Water Heaters

Natural gas tankless water heaters provide the most hot water for the lowest operating cost.

If you need more hot water to fill up your large whirlpool tub or to supply your multiple-jet shower, a tankless water heater would be a perfect fit. Speaking of perfect fit, tankless water heaters are only slightly larger than a briefcase and can free up valuable floor or closet space. Better yet, models are available that can be installed outside (flush-mounted in or mounted to an exterior wall).

FAQs:

Natural Gas Tankless
Water Heaters

How does a tankless water heater work?
Unlike storage-type water heaters that heat and reheat the same water 24 hours a day, tankless water heaters are more efficient because they only heat water when it is needed. When a water source is opened, the tankless water heater senses the demand for hot water flow and starts the water heating process. The water flows through a heat exchanger (similar to the radiator on a car) and is heated to the designated temperature set by the user.

What is involved in replacing an existing tank-type water heater with a tankless water heater?
In order to heat water quickly, a tankless water heater requires a higher heat (Btu) input than a traditional storage-type water heater. Because of this, the natural gas line will need to be larger. In addition, natural gas tankless water heaters require special venting material. If there are any questions, Arkansas Western Gas Company can assist in pipe-sizing and ensuring that the proper venting material is used.

If a tankless water heater requires a higher heat (Btu) input, how is it less expensive to operate?
The tankless water heater supplies higher heat (Btu) input while there is a demand for hot water. The storage-type water heater must keep a large volume of water hot 24 hours a day whether or not there is a demand for hot water.

Will there be water at the faucet instantly with a tankless water heater?
The speed at which hot water arrives at the tap is dependent upon the distance the water heater is located from the tap. This occurs whether the water heater is a storage-type or tankless water heater. A recirculating system can be installed that will move the hot water closer to all or desired taps, but these systems can be expensive to operate. Any time a circulating pump is used, a timer is recommended to reduce the operating cost.
