Best Prices Rheem Tankless Water Heater

Nothing to complain so far. This model supplies non-stop hot water for 2-3 bathroom house. You save some space too by replacing indoor tank water heater with a outdoor tankless water heater. Unit is about the size of a regular suitecase. No hassle of venting if you go for the outdoor model.You never run out of hot water. Installing it closer to the bathrooms and kitchen is a good idea, but keep in mind that instant water heaters are rated high BTU, and usually require a direct gas line from the meter. Insulating the hot water pipe will reduce the water waste waiting for hot water. That is true for tank or tankless water heater.Unit requires electrical connection since there is no pilot. I would recommend professional installation unless you are an skilled plumber & electrician.Also, remember to order the service valves which is required for installation. Not all valves meet the code requirements of certain states. So check before ordering the valves. An easy choice is "Rheem RTG20220AB" includes hot & cold water valves and pressure relieve valve. Please note that "Rheem RTG20220AB" and "Rheem RTG20220" look same but are not the same; "Rheem RTG20220" is not California (low lead) code compliant.

So far so good. I installed the heater myself. I would consider my level of expertise as intermediate level, if that helps.Overall I really like tankless heaters, this is my second one. My previous one was a Bosch. This one appears to be nicer. It has an electronic control so you set the temp (It will go as high as 140 degrees)and it will modulate the combustion air and gas valve to maintain the hot water setpoint.Let me address what some of the other reviewers are saying about the amount of water that has to flow in order to get the unit to fire. I think it depends on several factors. I can turn my faucets on maybe half way and the unit fires just fine and the water temp is great. If you have low flow shower heads you MIGHT have issues.If I turn on the tub half way it is great also. However, if I open the faucet on the tub too far the water temp is not hot enough for the wife. The heater cant keep up because it exceeds the capacity of the unit. The solution then is to only open it to my half way. Then the water temp is fine. This heater also has a combustion blower so it will require a 120 volt circuit close by. And if you are wondering it is very quiet.As was mentioned by some others, the flue will need to be stainless so that will add a considerable cost to the installation.All things considered I am very pleased with the heater. What we don't know yet, is how reliable is it going to be?Only time will tell.

I'm quite happy with this heater, except for 3 months out of the year. I live in Florida Tampa Area and figured this a warm climate, but if the temperature goes below 40 degrees the heater won't work, I have it in a carport shed, so no insulation. If I put a space heater in my shed and let it run for about an hour I'll get some hot water after leaving the faucet running for 5 min. The whole thing is very annoying to say the least.So overall I do not recommend this heater except if you live somewhere where it never gets below 50 degrees.

We have the propane model and have a super low electric and gas bill. Highly recommend them!!!

My gas hot water heater just died. Got quotes to replace with similar. Quotes ran from $1800 to $1250 installed. The tankless unit priced out at $2000 installed which included adding a larger gas line and tapping into electric. $300 fed tax credit, $100 from Rinnai and $150 from my nat gas company gets me to $1450. So for $200 I made the leap to tankless and should save at least that much in gas first year.First shower tonight right after install. Plenty of hot water. Can't speak to fluctuations as it was still clearing air in the lines. I gave it 4 stars only because it is too soon in ownership to award it 5 stars. More later...assuming I can update this later.Jan 23, 2012 Update:Update: It definitely takes a little longer to get hot water (30 seconds-1 minute). Of course once someone gets hot water upstairs the first time in the morning the lag time isn't really noticeable. And there is a "cold water sandwich" effect as mentioned on the Rennai site. I tend to get wet (turn water off), soap up, wash, (turn water on) and rinse. When I turn the water back on there is a short burst of cooler water. then right back to hot. This is more a function of how I shower but it is a consideration. Of course if you leave the hot water on it stays hot and you never run out. No issues with multiple showers - washing clothes - running dishwasher. It really delivers the hot water. I have a 5 person household (with 4 women).So I recommend it. Even with the slight delay I keep thinking…

I would rate the unit at a negative 100.One of the worst items I purchased. Water would fluctuate, be too hot to stand on the lowest settings. This was installed by professionals in a new house. I got several error codes. Finally had enough and called tech support. I was on the phone 2 hours the first time I called and that was on hold. Then I spent another hour playing games with the unit.We spent over 10 hours talking to tech support over a month's period. I had to switch the unit on and off to get a bath. Tech support said the supplier told me the wrong unit to buy. Another tech support told me that that was wrong. I had to take off a lot of time to get the gas and plumbing installers to come back and check their work which was correct.Finally I had enough and called the supplier. They worked with me to get me a credit. By the way that supplier no longer sells Bosch. Just give me your money instead of buy the Bosch unit. I can hand deliver consistent and dependable hot water better than Bosch. Oh yeah and you can get a straight answer from me without the long wait. Maybe the long wait shows that there are a lot of consumers that are having the same problems.Replaced with Rinnia and it works as designed.

The old water heater developed a leak at the tank. We decided to go with a tankless water heater as a replacement. This seller shipped the product faster than we imagined. The product was In perfect condition, and operates flawlessly. The water Is as hot as we could handle and never fluctuates or runs out. In a home with a wife and 2 female teens hot water was always In short supply before.It uses less gas so eventually the product will pay for Itself. Be sure to do research and get the right unit for your home. There are many variations for all situations. Indoor,outdoor,electric,natural gas,LP gas,and GPM all need to be considered before you make your decision.

This company has the worst customer service I have ever experienced. My brand new tankless on demand water heater has been nothing but a problem from day one. My plumber has been to the house 6 times in 2 months to try to fix this thing. Quietside will not replace the unit until you try replacing all kinds of parts & prove that the unit is defective. I have to prove to them that a brand new $1500 heater doesn't work? A brand new water heater shouldn't need to have parts replaced. I called the tech support department & the supervisor hung up on me when I told him this. The product is terrible & the customer service is worse.

We have had our Rheem tankless RTG-84xp for one year and love it. The water is hot very quickly and it stays a a constance temperture during use. We use propane for the fuel and did not notice any change on the tank's level gauge during the summer, I think the fuel use is lower than the energy guide shows. The use propane use in the winter is hard to tell because we use it for the furnace also. I am glad I purchased.

I'm not sure why anyone would not be happy with this unit (if it is installed correctly) but I have to say I love it. It was one of the best investments that I ever made for my home!! We have a 2 story 3 bathroom house and it works great for us(4)can take showers 1 after another and there is always hot water. My old 30 gallon tank would have been done after 2 showers. It is not perfect, using the washer or another bathroom can throw of the temp but hey there is always hot water...

I wanted to write an honest review of this product since I couldn't find much online about on-demand hot water heaters. Our tank broke, flooding the basement, and we wanted to look into alternative ways to heat our water efficiently. We're in Boston and the tap water here is about 45 degrees.The way this works is that when you turn on the hot water in the house, the unit senses the water flow and begins to heat up a set of pipes inside. As the water passes through, it's heated to about 122 degrees.The pros:- It works normally, just like before. I turn on hot water, I get hot water.- You don't experience any standby losses of having a tank - Gas is only used when you are actually using hot water saving both money and energy.- The water is very hot in the shower. We can also use the dishwasher OR the washing machine with the shower. All three would probably not work well.- There's no footprint. You put this on the wall, and it's vented outside.- If something breaks, you replace a part rather than the entire tank, saving time and money.- If it breaks, there's no flooding!- We received rebates from both the gas company and from the federal government through a tax credit for the "green" purchase.The cons:- It costs more than a traditional tank to both purchase and install. We paid about $1000 for the unit itself, and an additional $1000 to have it installed. We had to have someone drill a new vent (both out and intake), put in stainless steel and PVC piping, and re-route…

Bosch has the worst service department I have ever dealt with as a consumer. They refused to return any emails or phone calls after one of their tankless water heaters blew out our plumbing.Don't get me wrong, tankless water heaters are fantastic, but don't buy one from this company unless you plan to be on your own if anything goes wrong.

I had a Rinnai installed a few weeks ago and its as good as the company said. In the morning a bit longer to get hot water to the shower head, but beyond that it works great. It will take some time to calculate the pay back period, but since I had an electric heater, my guess is a payback period of about 3 years. Given the avg life of 20 years for these type of units, it's well worth the initial expense.

We replaced our tank hot waterheater with this tankless and couldn't be happier with our decision. It does seem to take a little longer (few more seconds) for the hot water to reach the faucets, which is nothing major. In return we get unlimited hot water.

I did a self installation. It was far more involved than just replacing my old water heater because its mounted on the wall requiring me to run all new gas and water lines as well as new venting to the outside. The extra work was well worth it. I performs wonderfully providing a neverending supply of steamy hot water. This thing is a godsend with a wife and 3 kids, all of whom love to take long showers. It performs exactly as advertised.
