While tank type water heater prices are rising, Navien has not raised their prices in their tankless units since they came out with their current generation of heaters a few years back. The newest generation has been running almost flawlessly for us and we are very confident in providing them now. Our units also come with a built-in circulating pump. In comparison to a 75-gallon power vent and circulating pump, the tankless will actually be a cheaper option. Just keep in mind that you achieve a maximum of approximately seven gallons per minute so if you have a car wash of a shower being installed, it may require more than one tankless. We recommend if you use electric instead of gas, to stay with a tank type water heater. If you have any question, feel free to call us or come on in and we will answer them!
