Never think about your hot water needs again: Innovative technology provides an endless supply of hot water whenever and wherever it’s needed – even for simultaneous uses at multiple fixtures. Showers and baths? Absolutely. Laundry and dishes? No problem. Prioritizing activities and scheduling hot water use is a thing of the past.

Endless supply of hot water

Never worry about running out of hot water again! Tank-less water heaters heat the water as you use it. Whether you are using one fixture, or multiple fixtures, individually, or all at the same time, the hot water will not run out!

Don’t wait for water to re-heat:

Unlike tank type water heaters, there is no tank to re-heat. With a tank-less water heater you truly have hot water on demand. There is no longer a need to schedule a daily routine around the availability of hot water!

Don’t wait for a tank to burst:

Tank-less water heaters do not have a storage tank that could develop a leak and flood your basement.

Multiple size units:

Multiple sizes of tank-less water heaters are offered to best fit your lifestyle, based off of your hot water need and usage.

Energy efficient:

Tank-less water heaters are 83% up to 99% efficient depending on the actual unit. Natural gas or propane is used more efficiently, resulting in less waste, and emitting less carbon dioxide into the atmosphere.

Variable gas valve:

Unlike a tank-type water heater, a tank-less unit uses a variable gas valve. This means that the water heater only uses the amount of gas necessary to heat the water passing through it, thereby using less gas, and wasting less energy.

Only heat water when you use it:

Whereas tank type water heaters heat and re-heat water constantly, tank-less water heaters only heat water when a hot water faucet is turned on. Unlike tank-type water heaters, natural gas or propane is not wasted on keeping a tank warm.

Digital display:

Every tank-less unit comes with a digital display allowing for easy setting of water temperature. Unlike tank-type water heaters, if a problem were to ever occur, the digital display would give an error code allowing for easy maintenance of a tank-less unit. Waste less space: A tank-less water heater hangs on a wall requiring less space than that of a tank-type unit.


A tank type manufacturer’s warranty is typically 6 years on the tank, 3 years on parts, and 1 year on labor. A tank-less water heater warranty is typically 12 years on the heat exchanger, 5 years parts, and 1 year labor.

Ideal installation is on new construction:

Installation cost for a tank-less water heaters is far less on new construction versus retrofitting an existing water heating system.
