“Works great! We live in Wisconsin so I was slightly worried our well water wouldn’t get hot enough, but we’ve been taking long hot showers just fine! So happy to not run out of hot water now!”
“The gas savings is out weighed by the increased water use. When one lives in an area that charges more for water leaving the house than water coming in the house, every drop counts. The tankless water has increased my water usage, which increased two bills while lowering the gas bill. As for dependable hot water, it is great, but for over all savings, it just isn't there.”
With a tankless unit you are heating the water that you are using as you are using it, saving energy. Water usage is determined by flow rate of the shower, sink and so on. Water cannot flow more with one water heater or another. That said it sounds like you maybe wasting water while waiting on the water in the pipes that has sat and cooled from the previous use, before the hot water from unit starts to flow. To prevent this and get instant hot water you would need a recirculation pump. Recirculation pumps recirculate the water through the system allowing for instant hot water at each point of use. I included a link to the recirculation pumps section of the site where can browse the different pump kits and get more information about how they work, and how they save water.

“It's a nice unit unfortunately I wasted my money the only way I can use it is to spend a bunch of money upgrading my electric that I recieve from the power company. Which in turn I would have to upgrade almost my entire fuse and wire system in my home. If I had a newer home this would probably be a great investment....”
“Has been running strong since installation about 1 year ago. Really happy with the performance, delivery and so much more. .a great buy and a great price for a tankless waterheater.”
“WHD folks were very helpfull and sent me the right unit and accessories. I replaced my old 1968 Rheem boiler and a 5 year old water heater with a new Rheem combination home heating boiler/domestic water heater. It is working great and we are seeing a monthly average 30%+ reduction in natural gas useage. It should pay for itself in 8 to 10 years, which is 2 years before the warrantee expires.”
“Hello I would like to tell you that I love my Tankless water heater RTEX-06.
I am using it in my dog grooming shop and having hot water on demand and not wasting energy heating water 24/7. I would strongly recommend this unit.”
“Love the tankless water heater, love the ability to have hot water after the teenagers are done taking showers. Technical support was a little lacking. Was trying to get help with the recirculation line and programming then unit. Takes a thermostat and momentary push buttons throughout the house. Also the one way check valve needed to be installed in a horizontal position, not vertical. Once it was up and running would never go back, takes a small amount of time to get used to it, but the days of the old water heater telling you it was time to finish the shower are over. Love it.”
“We love our new Rheem gas tankless water heater. So energy cost effective for us. Finding new ways to use hot water that before we would not try because we knew we would run out of hot water before we got through with project. Talked to Richard Romano before purchase to get the right unit and extras for us. He was vary friendly and helpful.”
