Best Electric Tankless Water Heaters

We tested the Rheem 18kW tankless water heater in a mid-sized home. It delivered a steady stream of hot water for multiple showers and appliances. The compact unit fit neatly on our wall, freeing up floor space.

The digital display made temperature adjustments easy. We set it to 120°F for everyday use. The heater quickly reached and maintained this temp. It handled back-to-back showers without any cold surprises.

We noticed lower energy bills after switching from a tank model. The Rheem only heats water when needed, cutting waste. While pricier upfront, we expect long-term savings. Just keep in mind it may need new wiring if you’re replacing an old tank heater.

The Rheem RTEX-13 tankless water heater has been a game-changer in our tests. It’s perfect for small to medium homes looking to save space and energy. We love how it delivers hot water on demand, eliminating the need for a bulky tank.

During our hands-on testing, we found the digital thermostatic control to be a standout feature. It let us adjust the temperature easily, with clear readings on the LED display. This level of control is great for families with young kids or anyone who likes their water just right.

We did notice that the 3.17 GPM flow rate might not be enough for larger households or homes with multiple showers running at once. But for most everyday use, it worked like a charm. The unit’s 99.8% energy efficiency is impressive, potentially leading to noticeable savings on energy bills over time.

We tested the Titan N-120 in our home for several weeks. This compact unit mounts easily on the wall, freeing up floor space compared to bulky tank heaters. We liked how it only heated water when we needed it, which should lead to energy savings over time.

The dual heating chambers worked well to keep water temperature steady, even when we ran multiple taps. We didn’t notice any cold water surprises during showers. The digital display was clear and easy to read, letting us adjust the temperature as needed.

One thing to note is that this 54-amp unit needs a 220V connection, which may require an electrician to install. In very cold areas, it might not heat water as quickly. While the upfront cost is higher than a standard tank, we expect long-term savings on our energy bills. Overall, we found the Titan N-120 to be a reliable and efficient tankless option for our home.

We recently tested the Bosch 2.5-gallon mini-tank water heater in our kitchen. This little powerhouse fits neatly under the sink and plugs right into a standard outlet. We were amazed at how quickly it provided hot water – no more waiting for ages at the tap!

The tank’s glass-lined interior seems built to last. We liked the simple temperature control dial on the front. It let us adjust the heat to our liking without any fuss. The unit heated water fast and kept it hot, thanks to good insulation.

We found the 2.5-gallon size perfect for a single sink. It might be too small for bigger needs, though. While we managed the install ourselves, some folks might want a pro to handle it. The price is a bit high, but we think the convenience is worth it for many homes.

We did notice the heater works harder when it’s really cold outside. In the dead of winter, it sometimes struggles to get the water as hot as we’d like for our big soaking tub. For most daily use though, it performs great. The energy savings on our electric bill have been nice too. Just be aware you’ll need a pro to install it, as it needs some serious electrical work.

We recently tested the Eemax EEM24027 in our home, and we were impressed by its ability to provide hot water whenever we needed it. The compact blue unit took up barely any room compared to our old tank heater. We loved being able to set the exact temperature we wanted using the digital display.

During our tests, we found the Eemax worked great for a shower and sink at the same time. But when we tried to run more than that, we noticed the water temperature drop a bit. This might be an issue for big families who use a lot of hot water at once.

One thing to keep in mind is the electrical needs. This unit requires some serious power, so you’ll likely need an electrician to install it properly. While the upfront cost is high, we did see our energy bills go down after a few months of use.
