Rated 5 out of 5 by from Electric tankless water heater Works fine for our needs, home with only two adults. Winter water temperatures forces you to reduce flow to maintain a 110F water temperature. So far the energy costs are lower than running a 50 gallon gas water tank. The extra space is a bonus. Must have 200 amp service to run this water heater it uses up to 113 amps when operating.

I'm interested in installing this water heater in my condo, which has 100 amp service from the main breaker. Is this enough power for this water heater?

Asked by: Jeff
I'm not an electrician, but probably not. The unit is fused with three 40A breakers and the docs for the 27kw list it at 112A For a condo, consider that you may not need the 27kw model. The 24kw model is 100A and the 18kw model is 75A. The size you need is largely determined by the incoming water temperature and the concurrent demand, since the size determines how much the temperature can be raised. I'm on a drilled well with REALLY cold incoming water and I was running the entire house (2 bath, kitchen, dishwasher, clothes washer) and my old 24kw was holding it's own with 112 degree water output. I actually had activation issues with my original unit because it required a high gpm to turn on the heating, and with a water saving head on my shower and nothing else running I had trouble getting the unit to switch on. I've not had that problem since switching to Rheem which activates at a tiny 0.3gpm which is perfect for me. According to the Rheem documentation, a 24kw going 4gpm will still raise the temp by 41 degrees. So if your incoming cold water is something like 60, that's 100 degree output. At 3pgm that jumps to something like 115 degrees, which is likely higher than you want it set anyway. Even the 18kw model will raise temp by 41 degrees at 3gpm and unless you are running a lot of concurrent hot water consuming devices you might not need even 3gpm. The Rheem unit comes with a flow regulating insert to limit the flow through the unit, so if you are finding that a smaller unit is having problems keeping the water at your desired temp you can install a flow regulator to limit the flow to 3 or 4gpm to solve that. The biggest "gotcha" that hit me was that the installation documentation provided with the unit is apparently for "US" electrical codes, and shows wiring separate breakers for each of the 220v connections (3 in the case of the 27kw). Apparently this is "not valid" for an install in Canada according to my electrician, which requires that all the power to the heater be on a single disconnection, so this isn't something you'll likely be able to self-install unless your familiar with the Canadian regulation regarding water heater connections and can wire it to code properly. I recommend you click on the bottom of the item display on the website and drill into the documentation. Rheem has some guidelines there for gpm ratings of different components so you can calculate a rough gpm for all the things you might have running at the same time that will be demanding concurrent hot water. Then, with the gpm in mind you can look up the water temp rise for each unit they sell and see which unit gives you the proper temperature rise. If you've never used an instant-on water heater, the general rule is that you set the max temperature based on the hottest shower you want to have. That person runs the shower 100% hot, 0% cold on the tap. Anyone else who likes cooler showers starts using some cold to drop the temp. I've got mine set for 112 degrees

The installation manual says this unit requires a red wire and a black wire for each element (so 3 red and 3 black), plus a ground for each (so 3 ground or green). Does it also require a white wire for each? (3 white)

Asked by: Nevima
Hi Nevima and thank you for your question. The 24kW and 27kW heaters require 3 sets of breakers and wires.

I buy this from edmonton and after 3 minutes there no more hot water and the water is not hot enough is it something wrong 

Asked by: Mark
Hi Mark. Thanks for reaching out. This unit should be able to provide an unlimited hot water supply up to a Shower, or a shower and a sink at the same time. If you feel there is something not right, feel free to reach out to Rheem technical support at 800 268 6966, and they should be able to assist. Hope this helps. Cheers.

Will this work efficiently on a 200 AMP circuit breaker ?

Asked by: Double02
Hi Double02. Thanks for reaching out. This unit would require 3 x 40 AMP DP breakers on 8 AWG wire. Hope this helps. Cheers.

With 2.5 GPM what temperature rise can be expected

Asked by: Glenn
Hi Glenn. Thanks for reaching out. You can use the following to guage performance. In farenheit, at a rise of 92 degrees = 2GPM, at 74 degrees = 2.5GPM, at 62 degrees = 3 GPM, at 46 degrees = 4 GPM. Hope this helps. Cheers.

What is the flow rate for this heater? Why is that basic and necessary information NOT included in the product information as it is on the HD U.S. webpage!?

Asked by: Maggie
Hi Maggie. Thanks for reaching out. The flow rate for this unit is around 2.5 GPM for Canada. There is some flux based on incoming water temperatures. Hope this helps. Cheers.
