Quality product at affordable price

I ordered this unit because my old natural gas tank water heater was past it's life expectancy. The first selling point for me was the price very affordable and actually compared to a standard 40 gallon tank heater it cost less. The next selling point was the reviews and ratings eccotemp already had and finally the energy efficiency aspect of the eccotemp only heating water when you need it. This unit is very well designed and appealing to the eye it installed very easily and started up the very first time even though I forgot to bleed the new gas line. Switching from a tank style water heater to the eccotemp takes a small lifestyle adjustment but this unit supplies plenty if hit water at a consistent temp. Just take the time to fine tune the unit and you'll be thankful you purchased this unit. Thank you eccotemp for bringing this type of water heater to the masses with your affordable prices.

Eccotemp by far the best product and support for any money out there.

As always, it was a good experience doing business with Eccotemp. Good quality, good price. When I use the word good, I am saying that it is the best it can be. The Judo-Christian Bible say no man is good no not one. By that standard of Good is my rating of the units I have received from Eccotemp. Thanks, George Wideman Brilliant, Alabama.

Great on-demand heater for the price

This was a replacement for another brands (AQUAH) "direct vent" on demand water heater which unfortunately froze on 2 occasions due to the method of venting. VERY pleased with the size and options for this model - easy to install and simple to adjust. We did have to custom fabricate an extension for the vent duct but even this was not a problem for "do it yourself" installation.

I love this brand

Bosch brand is over $1000 and I tried a different brand (AQUAH) but it froze up and flooded my laundry room during the first night of minus 12 degrees with its poor design allowing freezing air to enter thru the 3 inch exhaust pipe. I had an Eccotemp in a previous home and love it so I decided to go back to the brand I loved and found best suited.
