This water heater works great and is constructed very well. I'm using it inline with a large whole house natural gas water heater. The gas water heater is outside on one side of my house and it took forever for the tap water to get hot. My pipes are in the attic so it was easy to install this. I have this right next to shower pipes on a shelf and I get hot water instantly. Before this little water heater runs out of hot water, hot water from the large water heater will start filling it. Where I live, it costs 3x more to use electric over natural gas. If electric is cheaper for you, this water heater or a larger version may be all you need. I'm sure it would fit under large sink enclosures too. This one filled up with water it weighs about 100lbs. I like the traditional cylindrical water heater format. The parts are all standard water heater parts that you can pick up from any home improvement store. So, the only time I would have to contact Reliance is if the tank starts leaking. There are ports on top to optionally have the input and output ports on top. I used the top optional hot water port to add a second magnesium anode. I also replace the stock aluminum anode with a magnesium anode. I took regular 0.9 inch diameter magnesium water heater anode rods and cut them down to 10 inches with a reciprocating saw with bi-metal blade. I popped out or unscrew the plastic trim piece to fit a socket in there to undo the old one. I took it slowly using auto trim removers and large screwdrivers. I used an 18V Milwaukee impact wrench and everything came apart easily. I have a feeling a normal ratchet would take the port plugs or anode out easily too. I wrapped all the connections and plugs with teflon tape 6 times around. There are no leaks and I could position everything however orientation I wanted. I have ball valves on both side hot and cold water ports and brass street elbows to point the connections up. It's then connected to my piping with 24" flex corrugated copper connectors bent for heat trapping. The plastic drain is fine on this unit, but I replaced it with a dielectric nipple, 3/4 brass ball valve, 3/4 brass pipe to garden hose connector, and a brass garden hose cap. The ball valve allows for easier sediment removal and I've had the plastic valves get stuck open with sediment before. Inside, the top cold water inlet port has a pex dip tube as you would expect. The side hot water outlet has a curved pex tube that goes to the very top of the unit right under the hot water outlet port on top so you get the hottest water in the tank. Very smart! The tube moved easily to accommodate the second 0.9 inch anode. The water heater needs to be hard wired into your electrical system on it's own 20 amp circuit. The internal wiring is 12 gauge which is great. I don't have to worry much about it melting. Some other manufacturers may use smaller wiring which doesn't make sense. The temperature selector is under the front cover and it's easy to change the temperature. The heating element makes a quiet hissing type noise and is a basic $10 one. The water heater has a lot of insulation. I still bought a R-11 water heater blanket to cover it up. The three ports on top radiate heat. I covered them up with pieces of pipe insulation I had left over when I insulated my pipes. I also covered the top part of the T&P valve with 1" pipe insulation loosely placed. My unit was a little banged up when it arrived and the T&P valve was damaged. It leaked a lot. I ended up buying a standard one from the local Ace hardware store. There is no cushioning in the box. There is a little cylindrical plastic insert to center it in the shipping box and a couple of cardboard sheets for spacing. Amazon customer service was great! I am totally satisfied with this purchase. FYI, you can get a similar 10 gallon Kenmore from Orchard Supply (i.e. looks exactly the same as the 10 gallon version but with a Kenmore name plate) for about the same price or cheaper as this one. The 10 gallon version is bigger dimensionally but not by much. There are also larger versions still.

I purchased this hot water heater for supplementing my hot water supply to my home humidifier. I installed a tankless water heater without thinking about how it would affect my humidifier. After the installation, I realized that the humidifier does not draw enough water (drop in water pressure) for the tankless water heater to kick on. So, in comes the Reliance 6 Gallon Water Heater to supplement the tankless water heater, specifically for my humidifier. It does the job perfectly and because it's electric, it costs very little to operate. I'm totally happy with the set up. I must say, if you don't have any electrical back ground, set up is a challenge. It doesn't come with a simple 120V plug. Have an electrician to do the job right! I had it installed with a separate line and switch.

I used this water heater in my hunting cabin. I was mounted under the sink in a kitchen base cabinet. It works great and heats up in a reasonable amount of time. I gave it 4 stars because it doesn't have an adjustable temp on the water and because everytime I start up from cold, the pressure relief valve leaks until the water heater reaches temp. Not deal breakers and the heater is a really good buy.

Box looked like it was dropped out of the truck and had big hole in the side. No packing inside the box when I opened it. Hot water outlet had poked the hole in the box. I noted there were no thread protectors on the inlet and outlet. I give it a quick look over and looked good at first glance. I put it in my hunting camper out in the boondocks 2 hours away. That's when the trouble began. Fitting kept trying to cross thread. After an hour of trying to hook it up, I pulled the whole thing back out of the camper. That's when I noted the water outlet threads was damaged on bottom side where I could not see it. Being hours from a store, I had to pull the outlet off the old tank to replace the bad one. Reinstalled the water heater and it worked like a champ. Fire the guy who is packaging these because they have no clue what they are doing. As for the water heater, It is awesome and works great.

For the money it is a good little heater. It serves my wife and I very well and she has enough Hot water to take Her shower, shampoo and rinse her hair twice. Was very easy to install. Beings we live in our RV the old heater gave out and we replaced it with this model of heater. We installed it under the sink area where the old heater was. No remodeling required, it fit very well in it's place. We have a good source of electricity so no need of a propane heater.

Our bright and capable contractor installed one of these in a small kitchenette and couldn't prevent it from steaming, hissing, spewing water, and flooding the floor out of the catch basin I'd ordered with it. I made the mistake of having the contractor contact Reliance directly instead of the dealer. Customer service first told him that perhaps an expansion tank was needed, then told him to buy a new valve, which didn't fix the problem, then said that if he didn't have an ohm meter, we should hire one of its dealers to come out and diagnose the problem. I asked that they simply replace the faulty brand new product, which Ian, their C/S representative, said was "not an option" because it was bought through Amazon, which, I learn, was priced without a replacement warranty. I replied that this kind of C/S was from another era and would put Reliance out of business within 3 years. I finally went on Amazon and requested a return from its dealer. The dealer--the seller, was more reasonable to deal with and told me they would take it back. As to the manufacturer and its customer service, it's hard to say enough bad about either. Once the tank appeared completely drained for shipping, I cartoned it. It continued to leak into the carton, which I had to keep draining for the next 12 hours. It became a soggy mess which I reinforced with strapping tape. Somehow, UPS accepted this soggy carton (a miracle--good for them!) and remarkably, it made its way back to the dealer, from whom I received a full refund. So glad to get rid of it. We subsequently put in another tank which the contractor picked up from Home Depot. He installed it without incident and without any expansion tank which the Reliance tank needed.

Item shown not like what you're going to get. You will be rerouting your hoses. Pressure relief on other side. Hope your not in tight area.

From reliance I am sure it was a good product. However the picture on the "sales" page is not what they are selling. If you need a side outlet H2O heater as pictured then call and make sure what they are shipping. The one I got had the outlets on the top and so was not usable where I had to install it.
