    • Easy to install
Style: 6500W
I’ve been using the 6500W 240V Tankless Electric Water Heater for a few weeks, and it’s a surprisingly efficient little unit. It heats water almost instantly once the flow starts, and the LED display with touch controls makes setting the temperature easy and precise. The memory function is handy—it recalls my preferred settings each time I turn it on. Installation was straightforward, even for a smaller space like my RV. While it’s not meant for high-demand use (don’t expect to run a shower and dishwasher at once), it’s perfect for single-point applications like sinks or salon stations. Sturdy, compact, and waterproof to IPX4 standards—definitely a smart buy for on-demand hot water in tight setups. ... show more

    • Small contact water heater
Style: 6500W
Designed for use with parked power or generator, this contact heater produces hot water for showers and washing. Small footprint so it is able to fit under the sink. Recommended for utility.

    • Hot water in the laundry shed = game changer (and no beer interruptions!)
Style: 6500W
I ordered this tankless water heater for our laundry shed at camp, and I am so excited to finally have hot water for doing laundry. It works awesome — and the best part is the installation story. The guys connected it to the washer, and I heard minimal cussing, and nobody came in for a beer, so it must not have been too stressful to install. 😂 Now I have hot water in the shed, and laundry is actually enjoyable again (or at least not freezing). Highly recommend if you want a simple solution for hot water in a remote space. ... show more

    • Needs Dedicated Line for RV
Style: 6500W
Review Image by Phoenix Phoenix
This little instant hot water heater is small but powerful. I’m happy with the performance but people should consider that this is a 240 V system that requires more electric than a standard or older RV is likely to have. Many will need a dedicated separate electric line or a significant upgrade to the whole system. I would encourage a professional installation, when done right it performs well! ... show more

The media could not be loaded. I am beyond excited to use this tankless water heater in our small RV this summer! It’s compact, powerful, and delivers hot water instantly—no waiting, no bulky tank, just on-demand comfort whenever we need it. The 6500W 240V power makes a noticeable difference, even in a small RV, and the LED digital display with memory function is super convenient. I love that the touch controls are intuitive and easy to use, making temperature adjustments a breeze. It’s also IPX4 waterproof, which gives me peace of mind for installation in tight spaces like RVs, bars, or even a small hair salon setup. Installation was straightforward, and it feels very well built and durable. If you need hot water fast without the hassle of a traditional tank, this is a total game-changer. Compact, efficient, and smart—it’s going to make our summer RV trips so much better! 🚐💦 ... show more
