Question: Can this be winterized at a beach house?
Document: Rheem provides a wired remote control with wiring to route and mount inside your house, in my case the garage. You will not be disappointed if you go with this water heater brand.
Installation was quick and wiring was easy.Warranty is 5 years parts and labor, 12 years heat exchanger, which is one of the best. Efficiency is at 84%. Now tankless heaters can have efficiency up to almost 100% (condensing heaters, they're called) so if you are using this to heat a lot of water, then calculate a 15% savings in gas for a better heater into your equation. But for a small house or an outdoor shower, the price here is hard to beat.
We replaced an ancient 50-gallon electric water heater with this model about six weeks ago. We live at 9100' in the Colorado Mountains with well water and our home is about 2200 sq ft (2 bath, 5 people). We have had no issues with this water heater and are really happy/surprised at its superior performance. We have had multiple showers running with little/no loss in pressure and the temperature really stays constant, no matter where we are in the house.
I was met with glorious hot water...for 30 seconds then succumbed to the icey frigid water sent from the depths of the Arctic. Frustrated and cold since it was around 35 degrees outside, I dry off and go outside to see what the heck is happening. Long story short, I had put a Rubbermaid cabinet around the unit and up against my house to block the unit from the Colorado mountain elements and keep the pipes from freezing.
We new our water tank needed replacement when we bought the house but figured we wait and see how long it would go before we had to replace it. Well it finally went last month after 20 years. My husband wanted a tankless water heater and we were not quite sure because the prices were crazy. We found the Rheem for a wonderful price. My husband installed it and it was been great ever  since. We even got a rebate of 550.00 from Teco Gas for replacing the tank.
Purchased from amazon.com, received in original package and promptly. Package had tear and dent in cardboard, manufacture boxes it well and water heater was undamaged. This water heater replaced a Bosch tankless water heater I installed in my house 4 years ago. The Bosch never worked properly and reviews started complaining about the errors codes that constantly stop the water heater from heating or gives 'cold water sandwiches' when not tripping up on an error code that turns off water heating.
We are a two person household, so the size is fine, but if you have more people in your home, you may want to consider a larger size than the 6.4 gpm.The item we received had a faulty digital thermostat. Rheem sent out a new one... no questions asked. Excellent customer service! Very pleased with the item. I will update this review if we have any problems
This water heater came packaged well and was pretty easy to install. It is a shame that it doesn't include the high temp/pressure relief valve, but that is $20 at your local home improvement store.Read and carefully follow the instructions and you'll do just fine.
So far, so good! We had a large Rinnai at our last home, so I wanted a tankless for our new home. I assumed I would purchase another Rinnai, but Amazon offered such a nice price on this unit, I decided to take a chance on it. Piping hot water and it since it gets installed outdoors, it freed up enough space inside to add a storage closet! It heats quickly and offers ample water for our 2 1/2 bath home.
So far I can't distinguish the performance of this tankless heater from a tank type heater, and that's the true test.Do all the comparison shopping you want , but I predict you will return to this one. And the price is right.Don Wall
