Rated 3 out of 5 by from Still haven't used it yet We ordered this water heater to replace a standard tank water heater that no longer functions. It has taken us a long time to get someone to install it as we were trying to find a reasonable quote. Professional installation can cost easily twice the cost of the water heater. We are having the tankless water heater installed in a different location from where our original tank water heater was located. That might account for a slightly higher installation price. I recommend asking around first to find out how much installation will be before ordering the water heater so you can avoid delays and to have a better idea of the true cost of this product. That being said, I am looking forward to having an endless supply of hot water and not heating water when I don't need to.

Rated 5 out of 5 by from these work great but... they require a 3/4 gasline to work properly! most tank whs only have 1/2 ran to them,therefor check your gasline b-4 purchase.
