Features of the NPE-180A2
The NPE-180A2 is a high efficiency Condensing Tankless Water Heater. The A2 at the the end of this model number represents that it is the (A) advanced version and the (2) is the second generation, which is the newest and best version.
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-180A2 from Navien. The 180 in the model name represent how much heat the unit can produce to heat water up. For the NPE-180A2 you can expect a MAXIMUM output of 150,000 BTU/H. The amount of heat generated is directly related to amount of hot water a tankless can produce.
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, which is pretty cold. 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. We really only recommend the Navien NPE180 A2 in small homes and situations where only a few people are living in there. If you are looking to run taps and faucets simultaneously then you will really want to jump up to the model above this one at the least.
