setup was a little confusing, but the manual was helpful as well as calling customer service. so far the heater has been working great for the last 2 months.

I bought and installed the unit 4 monthes ago as a backup heating system because my existing system is getting older. I was impressed with the ease of installation of the combi although the Piping to it was serious to incorperate into my existing system. Doable though. I can run either system independantly or run both together at the same time. I do reccomend this unit but beware if your going to install it yourself. Make sure you understand the thermostat circuit befor you buy it. There is little to no info out there about it.

This replaced an old boiler AND a hot water tank. Installed ourselves and saved a boatload of money.

It was fun & quick installing on the wall and freed up a lot of space on the floor where the old style traditional boiler and water heater once stood. Water heated up really quick and the central heating should still be observed in the winter. Expected to run that without a hitch.

It took that boiler a month to begin its journey to my house and I still had to go and pick it up.

I bought this unit to replace my old 100000btu boiler. This unit is having no trouble keeping up with our demands love it.

I own a small construction company in Washington DC, and I installed this unit in my clients basement to replace a very old and in efficient boiler and tank water heater. The installation process was straightforward and easy. There were a couple things I discovered, one is that the unit actually has its own recirculation pump so if you only have one zone you will not need an external recirculation pump. The other is that you will need to tap into two areas for the auto fill function, one being the included hook up and the other being into your supply side on the hydronic heat loop.

It has only been in service for a month. With that said Installation was not that bad. Due to price and availability of CPVC for the exhaust vent it is running at the lower temperature settingand standard PVC(factory default) Our coldest day so far this year was 5deg F. With a 1300sqft 100 year old balloon frame house and no insulation it has done a good job of keeping the house at 71deg. I do not suspect that at this setting it will run 2 showers on the coldest day at the same time. I did notice a drop in domestic water temp while taking a shower and using the washing machine at the same time. I will say that with just 1 shower it works great. House is nice and toasty with endless supply of very hot water. It did shut down once due to a defective back flow-preventer that would not flow in any direction. You need to go in to the factory settings menu to clear the code before it will restart at full power. It seems to go in to a safe mode even if it detects the proper water level. You must clear the code for it to get back to normal temperatures. I do not see any of this as the fault of the unit. I knocked one star off because it did not come with a flush valve assembly. It is essential to clean these to keep them in good order. It should be included.

work well and don't have to worry about it .

After having to completely replace the first unit I installed in August because of poor quality, the second one I installed seems to be holding up, but I don't have much hope. Rheem tech support is horrible and they could only read from a computer screen what the issue could be! I went 4 weeks with no heat and hot water!

Easy install, good product

So far so good, it does exactly what it is supposed to do. This unit heats my garage and house as well as domestic hot water easily. No issues so far, and at a good price.

I AM IN MA STATE, GOT THIS BOILER FROM HOME DEPOT. NOW I CANT FIND A COMPANY TO INSTALL AND CANT GET ANY HELP FROM HOME DEPOT R RHEEM. DONT BUY IT UNLESS YOU NEED NEVER TO BE INSTALED OR SERVICED.

Well built unit. Straightforward installation and easy to understand manual.Provides more than adequate hot water. Cannot comment on heating operations until cooler weather arrives.

My plumber said this was pretty easy to install. The hot water it produces is great and the pressure is better than I had before. So far I have no complaints and feel great about this purchase

Works as advertised.( Maybe even better.)
