The Short Answer on the Camplux Tankless Heater
Best for: you need a point-of-use water heater for a single fixture like a bathroom sink or a small vanity.
The Camplux 11kW Electric Tankless Water Heater is a budget-friendly choice at around $118.98.
- Pro: A remote smart controller allows for installation in tight spaces under a sink.
- Pro: The pressure relief valve prevents freezing and cracking during winter months.
- Con: The 0.52 GPM flow rate is significantly below the 1.2 GPM high-efficiency standard, restricting it to very low-flow use.
- Con: The 11kW power requirement necessitates a 1 x 60 AMP double pole breaker, which may not be available in all residential circuits.
Don’t buy this if: you need to run a standard shower head, as the 0.52 GPM flow rate falls short of the 1.2 GPM minimum for high-efficiency fixtures.
Price assessment: At $118.98, this unit offers a low entry price for a point-of-use system with smart controls.
Green Writer score: 8.1/10 (data-driven – see “How we picked” above)

Before You Buy: Camplux Tankless Heater Checklist
The first thing to check is your electrical infrastructure, as the Camplux Tankless Heater requires a 60 AMP double pole breaker and 8 AWG wire to function.
- ✅ Confirm electrical capacity — 60 AMP double pole breaker and 8 AWG wire
- ✅ Verify water connection size — 1/2 NPT
- ✅ Measure mounting space — wall-mounted design
- ✅ Check remote controller placement — point of use design with remote smart controller
- ✅ Budget for professional installation — 240V electric tankless water heater
You should not buy this product if your current electrical panel cannot support a 60 AMP double pole breaker or if you require a flow rate higher than 0.52 GPM.
Performance: What the Specs Deliver
Rapid Three Second Heating
The Camplux 11kW Electric Tankless Water Heater provides hot water in three seconds after switching on. This rapid heating time allows you to access hot water almost instantly, which is ideal for quick hand washing or small point-of-use tasks where you cannot wait for a traditional tank to recover.
The Camplux Tankless Heater has a minimum water flow of 0.52 GPM. Because this is significantly below the 3.5 GPM threshold required for a standard shower, this unit is designed for single-fixture use. You should not expect to run multiple showers or a shower and a sink simultaneously, as the flow rate is insufficient to support multiple users or high-volume fixtures.
Winter Freeze Protection
The Camplux Tankless Heater includes a pressure relief valve to drain water after use during winter months. This feature allows you to protect the internal components from freezing and cracking, extending the lifespan of the unit in cold environments.
Digital Touch Control
The Camplux Tankless Heater features a touch control interface and digital display to set temperatures between 86F and 125F. This allows you to select a specific temperature and receive immediate visual confirmation of the setting.
The unit also includes a remote smart controller for easier operation. This layout supports a point-of-use installation, such as under a sink, where a remote interface allows you to adjust settings without reaching into tight spaces.
