The warranty excludes damages due to scale - what are the water quality requirements?

I have heard of many heat exchange failures related to mineral scale. The specific warranty exclusion seems to acknowledge this issue. Is this product not recommended for hard water environments? What are the water quality requirements?
Asked by: RR
It can be installed in hard water environments, but it is suggested to add a filter or a scale inhibitor before the water heater to help prevent build up and corrosion.

How much electricty does it use?

I am wanting to install this in an off grid location and am very sensitive to electricity consumption. What is the estimated KWH use annually for this unit. Also, it says it has a plug, so an outlet is needed, is there a hard wire version?
Asked by: Ben
Hi Ben, the electricity consumption is based off of your usage. This unit can be hardwired as well. Please consult an electrician for more information. We appreciate your business and look forward to serving you in the future. Thank you for shopping Home Depot.

What codes specifically does this unit not meet for manufactured home installation?

Asked by: Dave
You can use our tankless unit in a manufactured home because you can’t convert the gas on our water heaters.

6.4 GPM Liquid Propane Gas Mid Efficiency Indoor Tankless Gas Water Heater is rated 3.7 out of 5 by 18.
Rated 4 out of 5 by from Do your research. The installation instructions are very good for this item, but be very careful in ordering. Do you need an LP unit or a natural gas unit? DO you already have 3/4 in pipe leading from your gas source to the unit? Have you purchased enough of the special venting to make it to the exhaust area? Are you prepared to cut a bigger hole in your roof? Have you purchased the additional emergency and cutoff valves? Will the product really work for the plumbing configuration for your house, and will you be using water in sufficient volume to get the unit to turn on and stay running? Make sure the answer to all these questions is YES before you buy this. Kudos to you for looking for an eco-friendly solution. We discovered very quickly that what we ordered was not going to work; Thank You Home Depot for accepting our return.

Rated 5 out of 5 by from Very good product I have been using this water heater for a year now. It was a replacement for a tank heater. I am very pleased with the performance with this unit. I recently had 5 relatives visit and with everyone taking showers one after the other in two bathrooms the same time we never ran out of HOT water. My electric bill has also gone down a little because the unit I got is gas. Very pleased with this unit, I installed the unit my self but have been doing my own plumbing for 30 + years.

Rated 5 out of 5 by from Could not be more pleased with this purchase The 50 gallon water heater at my vacation home burnt out (due to a critter building a nest on top of it) so I took the opportunity to replace it with a tankless water heater. I saw little point keeping 50 gallons of water hot when I wasn't there so the tankless design will also save me money during the year. I decided to hire a plumber to do the installation and he had the old heater out in 15 minutes and the new one installed and providing hot water within 2 hours - very impressive. I could have probably done it in 6 hours but this was low investment for the satisfaction of getting it done right first time. The installation was delayed a week since I didn't order a vent kit - the special needs of this tankless heater could not be met with the previous venting system. I recommend other people order a vent kit at the same time as ordering the tankless heater. The plumber put the control panel next to the heater (see photo) - I will probably move this into the home to have the comfort of seeing the panel working! The near-instant hot water is GREAT and there is no chance of a critter building a nest on top of this one!

Rated 4 out of 5 by from Great Product with long install Great product and have used this for 1 year now. You can not run out of hot water. Watch install. Because this type of vent pipe is very expensive you will relocate the heater if converting from a standard tank heater just to minimize the vent distance. Note water inlet and outlet need 3/4 inch with consideration for draining water on loss of heat. The gas line install needs install with consideration that this unit in "high" uses as much gas as a whole house furnace. Electric circuit should be GFI. Oh, and don't forget a place to dump the condensate drain. Depending on your local gov you will need between two and four building permits to convert from a tank heater to this unit. I am completely satisfied but did spend 20 plus hours on a quality install and had to have two inspections to comply with permits.

Rated 4 out of 5 by from Does the job Easy install - performs as expected - on track for fuel savings.

Rated 5 out of 5 by from Excellent product. Use it to heat water for horse barn. Easy to install. Online purchase was simple. Heats only water when needed.
Date published: 2013-11-20
Rated 1 out of 5 by from important venting issue nobody tells you this at purchase time but special class 3 concentrical venting is required, it can not be purchased locally and can only be bought in certain lengths and it can not be cut, going on my second week without hot water, cost extra to have venting overnighted, even without freight 22 feet of venting cost as much as the heater itself.
Date published: 2015-03-21
Rated 5 out of 5 by from Better than more expensive one that it replaced I was very pleased with the results. I have an endless supply of hot water and it holds the temp even with my well pump pressure. You do not have to be a plumber to install, just need a few simple tools and a couple of hours.
