On Demand Water Heaters

We provide two types of Navien tankless water heaters, condensing and non-condensing. You can install both types inside and outside, and both offer lower operating costs than storage tank heating systems. Non-condensing water heaters are considered high-efficiency, with a UEF rating of 80 or greater, while condensing water heaters are considered ultra high-efficiency, with a UEF rating of up to 98. Condensing tankless water heaters usually have the lowest operating costs, but their initial costs are usually slightly higher than non-condensing water heaters. Overall, both types are much more energy efficient and cost effective than storage tank water heaters, and they’re also 70%-80% smaller than storage tank heater types.

Navien provides natural gas and electric water heaters, and we can help you decide which type is right for your home. Tankless electric water heaters are easier to install, since they don’t need any venting kits or pipelines. However, natural gas water heaters tend to be more energy efficient, and Navien tankless units generate heated water very effectively with natural gas.

Ultimately, whether you choose a gas or electric heater often depends on which type of installation will fit best in your home. For example, if we’re replacing another Navien unit and you already have a pipeline and a venting kit in place, we will most likely install a natural gas tankless water heater.

Whether they’re condensing or non-condensing, electric or natural gas, the NPE series of Navien tankless water heaters provides small, sleek heating appliances for your home. Each heater is about the size of a suitcase, much smaller than the average storage tank water heater. The water heaters have smooth, slim, rectangular shapes, so they don’t jut out into the rooms where you install them. That way, your Navien NPE tankless water heater takes up little space while it produces heat in an energy efficient way.

Condensing water heaters operate with two heat exchangers, one of which heats cold water, and then the next heat exchanger heats that preheated water. Then that water travels to the activated tap, which the water heater senses. Then the condensing heater starts the igniter, and the heating process begins. Non-condensing water heaters also sense the activated tap and start an igniter, but it uses just one burner to heat the water before it goes to the tap.

As stated above, on-demand water heaters use less energy and space to operate, and they reduce your overall utility costs. They can also provide unlimited hot water while operating within their operating capacity, so you can use hot water for long periods of time without running out. They also have a 20-year lifespan, while storage tank heaters have 10- to 15-year lifespans. On-demand tankless water heaters offer you efficient heating operations without sacrificing your access to hot water.
