Product Overview

The GE tankless gas water heater has arrived, providing what no old-fashioned, tank-style unit ever could: a continuous flow of precisely heated hot water. here's no tank to run empty, or take up space. Compact design allows for installation in a closet or even tucked away under stairs. Flow rates may diminish based on simultaneous use of multiple showers/baths and /or appliances.

  • There's no tank so it can't run empty and the water stays hot until you turn it off
  • Could help you save up to 35% in water heating costs on your energy bill annually, based on 2007 fuel costs and testing conducted by the department of energy
  • Constant monitoring and adjusting assures the hot water flowing from your faucet or shower head remains consistently within three degrees of the heater's set point
  • The heating system activates only when the hot water tap is opened, and turns the heater off when the tap is closed
  • Your tankless heater is capable of providing continuous hot water even when multiple showers, tubs, sinks or appliances are in use at the same time
  • The control unit displays the set temperature and provides diagnositc codes for easier service and maintenance

We currently have a w/h with a power vent. How must this tankless be vented?

This question is from 7.5 GPM Indoor Tankless Gas Water Heater-DISCONTINUED
Asked by
Judy

We are converting from LP to Natural gas and will have to replace the old water heater which is a 50 gal with a power vent that vents out the wall. Can this be installed in the same way with a power vent? If we install a tankless (and change locations) can it vent through the roof vent for the boiler? There is no chimney.

Answer: 
Most of the tankless are direct vented with a double wall pipe that brings in fresh air and lets the exhaust gas out. It can not be hooked up to a chimney, they have to have their own direct vent through the wall preferably to be able to bring in the fresh air .

Greetings Judy,
I saw your question and saw the response from George one of our Home Depot experts in the How to Community. I will try to address the question in a different manner after getting clarification from the manufacturer.
First it cannot be vented in the same way as the heaters they carry no longer use power vents.
Second, If you install a tankless heater, it must have it's own vent and the venting can not be shared with the boiler.
Finally, the tankless can be vented through the roof, or through a wall as George stated, but in a certain manner. More information can be obtained through the Technical Support Line of the Manufacturer. For your convenience it is 800-431-1549.

Answer: 
We had 2 of these installed, and with part and labor they were about $1000 ,but that is because of the cost of the double wall pipe and we had to run it almost 30 ft from the heater to an outside wall.

Answer: 
Expect it to cost about $1000 depending on how much double wall piping you need. If you can install it on an exterior wall the price will be drastically less. The cost comes down to having to reroute all the water and gas piping from where your current tank is,to the wall where the tankless will be mounted. Licensed gasfitters do not work cheap

Rated 3.1 out of 5 by 7 reviewers.
Rated 5.0 out of 5.0 by owner i bought it good work very nice so for i have no problem December 11, 2015
Rated 5.0 out of 5.0 by Great Savings I bought & installed this water heater in our house about 11 months ago and the savings on gas was awesome! We use a gas dryer, range, furnace & water heater. Our monthly budget was $98.00 with an old 40 gallon tank type water heater. Our new budget is now $48.00. Install is a little challenging but, not impossible. Download & read the directions completely before you start the insatllation to make yourself farmiliar with the product. You can get the specialty venting & installation valves on line or at your local wholesale plumbing supply house. All in all. A great value!! July 20, 2012
Rated 5.0 out of 5.0 by Great water heater! I installed this water heater in my house about a year ago and I couldn't be happier.I have not had a sutuation where it could not deliver enough hot water (I can run 2 showers and the dishwasher at the same time). The installation is a bit more difficult than a tank water heater but it just takes a little research and you will find all the information needed to install it. You can even download the installation manual before deciding if you want purchase/install yourself. The concentric vent pipe is available online. November 26, 2011
Rated 1.0 out of 5.0 by Tankless water heater This appliance is NOT for the average homeowner to install. It requires professional knowledge and specific vent pipes that are not included or even mentioned in it's installation directions. The manufacturer helpline also didn't mention them. Contact a licensed pro to figure out what the REAL cost will end up being. January 10, 2011
Rated 1.0 out of 5.0 by The problem is installation Requires separate gas line run, electric outlet, and venting like a gas fireplace. $2000+ for installation. Puts the energy payback out 20 years! November 14, 2011
Rated 4.0 out of 5.0 by Works great we bought 2 Any local WHOLESALE plumbing supply store will have to vent pipe available. Yes it is a shame HD does not stock it or even have it available for special order. DO NOT go to your local HD because they will give you the REEM kit which WILL NOT fit the GE. Nowhere does it say this is a do-it-yourself job, and unless you are comfortable (and licensed) to reroute gas lines do yourself a favor and hire a licensed gas fitter. With the direct vent piping and everything they cost us just about a grand each to have them installed. As far as the product itself it works great. Occasionally I think there is a burb in the software and it will not heat to the desired/set temp. Shutting off the faucet/shower giving it a couple seconds to shut down than opening the faucet again seems to fix this issue. As far as savings, our gas bill is nothing, and we can fill our 500 gallon hottub with 100* water right from the hose and save it taking 2 days for the hottub heater to bring it up to temp. With Nstar charging $12/month to be a customer our gas bill during the spring thru fall averages about $14, whereas it was $50-$60 with our old water tank. So it has pretty much already paid for itself in under 2 yrs. September 27, 2012
Rated 1.0 out of 5.0 by Stay away! Horrible experience. Vent kit is impossible to find. Rheem will not work. Stay away! September 10, 2011
