Rated 4.7 out of 5 by 3 reviewers.
Rated 5.0 out of 5.0 by This is an EXCELLENT Product I have been researching Tankless Water Heaters since they first came onto the market. I did not purchase one until I read the specifications on this model, and I was immediately sold. I knew from the very beginning that this product would be difficult to install because of the plumbing involved. I hate plumbing because it requires so many skills to do it. I prefer electronics, but have the skill for doing the necessary plumbing for the installation of this product. The notes on the box were to say the least just a little scary because they want to make sure that everything should be right before you even open the box to start the install. You tend to get the feeling that you might have purchased a boat anchor if you do not understand the requirements of the product. Otherwise you should hire a professional plumber before you even purchase it. Read the Installation and Owners manual before you purchase this product, and make sure that you understand the installation and requirements if you are going to install it yourself, because the level of difficulty is extreme if you have no experience. I got the product installed, and the natural gas connected. It took a few seconds for the unit to power up, which was a little unsetteling at first, but when it did I was very pleased and impressed with its performance. The reason that I purchased this particular model was the fact that the flow rate to activate the burner was .4gpm which is extremely low. All previous models that I researched were beyond the rate my plumbing would provide. It was also great to vent because it only requires 2 1/2 to 3 inch PVC pipe which can be run out the side of the enclosure and not through the roof. You do have to provide a plastic hose to run into a sewer drain for the condensate because of its acidic properties. The unit activates easily, and is so sensitive that if you turn a faucet on for a second, the unit sees the flow, and powers up the burner. The hot water provided is consistent in temperature, and there is very little depletion in flow if you are running the hot water in a sink, and the washing machene kicks on to fill with hot water. The water stays at the set temp. I would recommend purchasing the next size up of this model if you have a large residence or use tremendous amounts of hot water at the same time as a large family would require. I also added a Uninteruptable Power Supply on the 110v supply because this unit is full of electronics, and I do not want the power company power to cause the circuit board to fry requiring a professional to come and replace it. Also I am going to add an electronic water softner on the cold water input side to eliminate slime and scale from the city water to foul the equipment. All in all, I HIGHLY RECOMMEND purchasing this product because from its performance over the last week since I finished installing it have been truly satisfying. March 5, 2012
Rated 4.0 out of 5.0 by Love it So much better than having a water tank that you have to pay to keep the water hot all the time. This is a good investment. January 11, 2012
