What Is a Tankless Water Heater?
A tankless water heater heats up water on demand instead of storing heated water in a storage tank.. Due to its short heating time, tankless water heaters are perfect for cooking areas, additional bathrooms, or any place where water needs to be used at any time. Also, because of its rapid heating and small size, our tankless water heaters are 90% smaller than a traditional water heater.

Amazing

Overview: As Described. Experience: So easy to install as a replacement for my old tank heater, same wiring requirement meant no expensive rewiring and since it is so small I was able to relocate a few feet and reclaim the old space for a room addition. Hot water fast and consistent no more waiting for a bath. We will see on cost savings but figure about 15% savings depending on usage.

A lot Of HOT Water

I replaced a existing tankless water heater with this one so installation was simple. All of the wiring and plumbing were already in place. I know from previous installs it is not too difficult but depends on your're abilities. I know a little about a lot of things and a lot about none. If you know some basic wiring and plumbing this should be a semi easy install, if not have some one else install it for you. One thing I like about this water heater is it has a temperature read out on it where my old one was just a guessing game when getting it set right. This is a good well made tankless water heater I expect to last me for many years to come. 5 STARS

Works great for my 1 bath house

This was relatively easy to install. The installation instructions were easy to follow. If you are not able to do plumbing and electrical hookups by yourself, I strongly suggest a professional install. Installation took about 90 minutes for me. The tankless water heater is light enough that hanging it on the wall by myself was not a problem at all. I have a one bath house, and I live in the Northern Midwest where the inlet water can get pretty cold in the winter months. It is rated for a two bath house, and in a warmer climate, I am sure it would be able to handle two people showering in different bathrooms at the same time. If you live where it gets cold, I would only count on one shower in use at a time. I can run the dishwasher and the clothes washer at the same time and both are getting great hot water (nobody showering). I love that I am no longer paying to heat water while I am not using it. Heating the water as it is being used makes so much more sense to me. Never running out of hot water, no matter how long I decide to shower...even after my wife just took a nice long shower, is so great! I am very happy with this water heater. I am giving it the full 5 stars!
