Frequently Asked Questions:

What is a Tankless Water Heater?

Conventional water heaters require large amounts of time and energy to warm an existing tank of water to a desired temperature. If you have exhausted your supply of hot water or have just adjusted the tank temperature, you’ll need to wait a while for access to warm water.

A tank-less water heater, on the other hand, gives you instant access to hot water. Since cool water is warmed as it passes through the device, you have unlimited, instant access to warm water. This, in turn, a tank-less water heater conserves energy and water and saves you time and money. In fact, when installed at each hot water faucet, tank-less water heaters can be up to 40% more energy efficient than the conventional water heaters.

What are the advantages of a tankless hot water heater system?

Also known as a point of use water heater or an on demand water heater, this innovative product generates hot water immediately when you open the hot water faucet. The unit then turns itself off when the faucet is closed, thus saving energy costs over the entire lifetime of the unit. The energy consumed is only for heating the water that is needed for that specific time. Since there is no storage of hot water and no constant heating and re-heating of water as in standard water heaters, you’re not wasting energy when you don’t need it.

The energy savings of the gas tank-less water heater translates to dollar savings for you and reduced impact on our environment. Typical savings are approximately 30% of your energy usage. Furthermore, a tank-less water heater produces an endless supply of hot water, provided you size the unit appropriately. Point of use water heaters are also designed to last for 20+ years and can be mounted to a wall to save space.
