We have just moved into a new place and the Rheem Metro Max minus the continuous hot water, that's right, no hot water. Ok monitor displays 11 then flashes to C2 have rung my Carrier AGL who wants $265 call out fee as an emergency then $65 ever 15 minutes. How rude. This Rheem is rubbish and will have it ripped out on Monday, and I will not be bearing the cost.

I have an integrity 24, unit has worked well until recently the hot water became tepid. I rang Rheem and they said it was most likely the temper valve. I got them to come out and was told it was a $143 service call, which included the first 1/2 hour labour. Thought that is reasonable. It was the temper valve and then said to replace it would cost $440 !! This is a part that you can buy from Bunnings for about $120. A word of warning to everyone, don't use Rheem to fix, just call a registered plumber, you could get it fixed at half the cost. Rheem are a complete rip off, and when my system finally gives up, one company I wont be using is Rheem.

We have our system for 4 years and the fan packed up. Rheem says its out of warranty and will not do anything. New fan cost to get fitted is $700.... New system $1200. The is a small item which may costs $40 to make. Rheem has no parts in the ACt so only place to get parts is Rheem Sydney. This Rheem product is a waste of time and I will never use them again. Think twice before buying these Rheem products. You will have trouble getting parts and you will be left in cold Camberra with no hot water.

I'd call this unit an "occasional lukewarm water system". It takes ages for water to get warm if at all! We have now resorted to boiling water on a stove for domestic uses. Back to Middle Ages! We have then to haul the hot water upstairs in buckets for kids bath! We brought a Rheem technician in who only blamed gas pressure without explaining what that pressure should be! Brought a qualified gas fitter in who clearly said that the unit is faulty. The unit is still under warranty but we have to make do without hot water. Wonder what it would be after the warranty period. With the number of complaints on this site, Fair Trading should have a look at this and reassure us!

We are now at the stage where we are lucky to have any hot water at all. I can run a whole tub of water and it is cold. Then after having to boil water to wash, I may strike it lucky and turn the tap on and it occasionally is hot. Although we have contacted Rheem they have not rectified our problem. Error code 11 then C2 appears on the system.

Waste so much water waiting for it to warm up, was an expensive unit requiring installation of elec unit to start up, therefore if elec goes off cannot use. Will not be recommending this to anyone. Feel I was sold a poor replacement for Bosch. Maybe should have chosen to go 100 percent elec with discounts and solar.

This is a terrible unit for 'instant' hot water. It takes at least 2-3 buckets of cold water before the hot water actually comes through. We bought a brand new apartment with this model (875E24nf) gas water heater installed and are completely unhappy with it. We would never recommend it to anyone.

We had the Rheem 27 for 3 and a half years and it worked flawlessly, until it threw in the towel 6 months after the warranty was up. Rheem service guy said the circuit board had gone and it would cost us $700 for a new one. $700! Ridiculous. Advised to spend a bit more and put in a whole new unit with a new warranty. This replaced a 13 year old gas storage unit that had never given us an ounce of trouble. Avoid if you can. Service guy was excellent though, replacing the unit same day, $1250 later.

my plumber installed the rheem 24 approx. 12 months ago and we had issues with the hot water cutting in and out so I got my plumber/gas fitter back a number of times to fix it but after checking the gas flow, pipes, tapes etc we still haven't solved the problem I need this fixed as it is becoming dangerous for my kids.

Bought 2 years ago now keeps saying error 11 on and off and then no hot water. Rheem out 14/7/14 said gas pressure too low ring ATCO. ATCO out changed regulator checked pressure all good. Still said error 11. ATCO out again upped pressure to 1.6. Still error 11 on and off. I paid for independent gas fitter to check system gas good electric good and error 11 means failure to ignite. Still error 11 so rang kleenheat who installed system. They sent out rheem again and they then said needs wider piping. So rang kleenheat they say nothing wrong with piping. Still says error 11 can anyone please help I'm not paying any more money as system is still under warranty its driving us mad.

ERROR 11

I would call this model a warm water system, it definitely does not deliver hot water. What's annoying is that I rang Rheem to find out how to adjust the temperature level to be told that this model is not changeable. The positive is that your young children will never get scalded from this model.
Continuous flow at full pressure
Water not hot, warm at best
