Tankless Water Heaters

Tankless water heaters represent the latest in heating water for your home. With so many advantages, it’s no surprise that they are in high demand. In fact, ABEND installs and services tankless water heaters to bring you “on-demand” hot water.

Energy Savings

When you install a tankless water heater in your home, you will likely notice savings immediately. Because they use less energy, tankless water heaters are more efficient. Actually, coupled with the fact that many use propane or natural gas as their energy source, the savings can be significant.

“On-Demand” Water

It sounds good, but you might be wondering what the heck that means. Actually, a tankless water heater works by heating the water when you turn on the tap. The stainless steel chamber heats water instantly and continuously. A standard old-school water heater has to maintain hot water at all times, whether you need it just then or not. That’s where the energy savings come in!

Upfront Costs for Tankless Water Heaters

Admittedly, the upfront costs for a tankless system are not insignificant. You must have them installed by a professional like ABEND Services to maintain your warranty. With the energy savings and the improvement to your hot water, most people find that the upfront costs pay off relatively quickly.

Tankless Water Heater Brands We Install

We install the best brands in the market, Navien and Rinnai. In general, both brands will keep you in hot water for a long time. Compare both brands and then call us for a consultation. We’ll be happy to help you decide based on your needs.


Navien includes a standard and controlled recirculation residential tankless water heater warranty for 15 years for the heat exchanger, 1 year for labor, and 5 years for parts.


When it comes to Rinnai, their warranty period is going to differ depending on which series you’ve decided to have installed. Heat exchangers will be warranted for 10-15 years. Labor coverage lasts 1 year, and parts for 5 years.
