Bought this hotwater heater for our summer cabin. Its perfect because we only make it down a few times a year and I dont have to drain 30-40 gallons of water in the winter, or wait hours for it to heat up. I did have an issue with the unit shortly after installing but Wintemp was great to work with, stood behind thier product, an resolved the issue quickly much to my satisfaction.

Absolutely recommend this tankless water heater! I purchased the WINTEMP 18kW 240V model for my house, and so far it has exceeded expectations. The water heats up instantly, and the LED temperature display is super convenient no more guessing! It’s very compact and saves a lot of space compared to traditional bulky heaters. I love that it’s self-regulating, so the temperature stays stable, even with multiple showers running. The WiFi control feature is a bonus adjusting the settings from my phone is easy. If you want endless hot water with great energy efficiency, this is a solid choice.

Update: 4-3-24 This company has reached out to me and we are currently going through a process of examining a similar unit in order to clear up any issues. I will report back on my findings after this is complete. ———————— I bought this unit to replace a unit we purchased in the past that ended up not working. Pro’s: -if you already have the smart home app that connects to this - connection is SUPER easy & the app is highly responsive when it works -it’s a good looking case on your wall -the over all heaviness to the unit is not too bad. Con’s: (they outweigh the pro’s) -the case feels like cheap plastic -the front cover attaches to the unit via snap in clips which are HARD to detach when you need to open the unit for installation. -the holes for the electrical lines are very “not firm” and there is no clamp included to keep those power wires in place. They basically just pass through an open air hole & connect via small flathead screws to the units receiving power ports. -both inlet & outlets are the usual 3/4” you see on most units, BUT they are pretty close together which makes planning your pvc connections below a bit challenging. I choose pvc unions so that the connections could be screwed on independently, but i still have to space them 1 below the other(see photo) -the entire unit is expected to be mounted with picture style hanging holes in the rear case. It’s the kind where you measure the distance between holes screw in your screws & hope everything lines up when you go to hang it. There are better ways to design your mounting options & this company did not choose them. -hot water but only IF the flow rate isn’t too strong. If too much water passes through the unit too fast, this unit doesn’t even try to keep up. It just shuts off. -once you’ve got the flow rate dailed in, then it randomly stops producing that hot water again. -the app will literally show you in real time what the unit it doing. So i can load the app, stand at my kitchen sink, turn the hot water on & watch as it super heats the water. I’ll begin washing dishes & all of the sudden - the unit stops heating, goes into standby mode & gives up. So I’ll continue washing dishes in cold water & all of the sudden, the hot water will begin again. It’s really confusing. -no visible customer service. I went through Amazon support because that’s where i purchased it. Not once in the chat did the representative say they would contact the seller. All they said was i could get a refund & send the unit back so that’s what i am doing. Notes: my whole system is pex 1/2 with the exception of the 3/4” supply & return of the water heater. I ran 3 1/2” lines of hot water. 1 to my bathroom sink, 1 to my tub, 1 to my kitchen sink. After learning this unit doesn’t perform with the correct installation, I bought a replacement & it’s already installed & working. Now i will return this unit & move forward.

I really wanted to install this unit but when I added up all the circuits I was over budget and had to install a lower amperage unit. Wintemp Customer Service was very responsive and solved my late return problem very quickly. Excellent Service. I will go back to them in the future.
