    The A or Advanced model has a few more built in features over the S (standard) version tankless water heater. Purchasing the Advanced Navien tankless gets you a built in buffer tank as well as a built in re-circulation pump. If you are looking to run a hot water re-circulation loop or possibly add some sort of heating (towel warmer, hydronic floors, forced air) with your tankless than the NPE-A2 is the model you will want to go for.


    NPE Tankless Sizes

    The tankless unit we are discussing is the NPE-240A2 from Navien. The 240 in the model name represent how much heat the unit can produce to heat water up. For the NPE-240A2 you can expect a MAXIMUM output of 199,000 BTU/H. The amount of heat generated is directly related to amount of hot water a tankless can produce. This is the largest tankless that Navien builds for residential home owners, therefor it is the biggest and best tankless that they offer!

    The temperature of the incoming water that the tankless needs to heat can significantly affect its hot water flow rate. For example. A Canadian home in winter can see their homes incoming water temperature dip to 5 degrees Celsius, or possibly even colder. In this example a tankless needs to heat that 5 degree water up quite a lot to make the shower comfortable and the more power (BTU/H) your tankless can produce the more hot water you get in your home.

    The NPE240-A2 model is probably one of our most installed versions as it has a lot of room for expansion and growth. If you decide to put that extra bathroom in a year after this tankless was installed, no worries, it has plenty of power to supply hot water to both bathrooms at the same time. It is a great combination of both efficiency and power for most homes in Canada and Northern states in the USA.
