Introduction
Hot water is no longer a luxury—it is an everyday necessity in modern homes. Whether you are washing dishes, cleaning vegetables, or washing your hands, waiting for hot water wastes time, water, and energy. Traditional tank water heaters often fall short in small spaces, apartments, offices, RVs, and point-of-use applications where efficiency and immediacy matter most. This is where compact electric tankless water heaters come into play.
The CAMPLUX Tankless Water Heater Electric 6kW at 240 Volts is designed specifically for point-of-use installation, delivering instant hot water exactly where you need it. Engineered with self-modulating technology, a smart digital temperature display, and multiple built-in safety protections, this under-sink unit provides a practical solution for kitchens, bathrooms, and utility areas.
In this in-depth review, we examine performance, energy efficiency, safety, installation requirements, usability, and real-world applications. This article also includes an accurate product data table sourced from Amazon-listed specifications to help you make an informed buying decision.
Product Overview
The CAMPLUX 6kW electric tankless water heater is a compact, CSA-approved point-of-use unit that heats water only when required. Instead of storing hot water in a tank, it activates instantly as water flows through the system, providing hot water within seconds. This design eliminates standby heat loss and significantly reduces energy consumption.
Operating at 240 volts with a 6kW heating element, the unit is capable of delivering a temperature rise of up to 50°F at 1.0 GPM, making it ideal for low-flow applications such as handwashing sinks and kitchen faucets. With adjustable temperature settings between 85°F and 131°F, users have precise control over water output.
Its slim profile allows for easy under-sink installation, while the intelligent touch control panel displays real-time water temperature and inlet flow, enhancing usability and confidence during operation.

Instant Hot Water Performance
One of the strongest advantages of this electric tankless water heater is its ability to deliver hot water almost instantly. Unlike tank-based heaters that require preheating and reheating cycles, this unit activates only when water flows through it.
At a flow rate of 1.0 GPM, the heater can raise incoming cold water temperature by up to 50°F, which is sufficient for most handwashing, dish rinsing, and light cleaning tasks. Hot water is available within approximately two seconds, reducing water waste and improving convenience.
This instant heating capability is especially useful in homes with long pipe runs, where traditional water heaters waste gallons of cold water before hot water reaches the faucet.
Energy Efficiency and Cost Savings
Energy efficiency is a major selling point of the CAMPLUX tankless electric water heater. Because it heats water only when needed, it avoids standby energy losses associated with storage tanks. According to performance estimates, this type of system can help reduce energy consumption by up to 50% compared to traditional tank heaters used for similar point-of-use applications.
The self-modulating technology adjusts power output based on water flow and temperature demand. This ensures that the unit uses only the energy necessary to maintain the selected temperature, avoiding unnecessary power draw.
For homeowners concerned about rising electricity costs or environmental impact, this efficient heating method provides a more sustainable solution without sacrificing comfort.
Compact Design and Space-Saving Benefits
Space constraints are a common issue in apartments, condos, offices, and RVs. The CAMPLUX 6kW under-sink water heater is engineered with a slim and compact form factor, measuring just 10.95 inches high, 7.4 inches wide, and 2.52 inches deep.
This low-profile design allows the unit to fit comfortably beneath most kitchen or bathroom sinks without interfering with storage or plumbing layouts. Its wall-mount configuration keeps it securely in place and accessible for maintenance.
For homeowners remodeling kitchens or bathrooms, this compact heater offers flexibility and convenience without requiring a dedicated utility room or large installation space.
Intelligent Touch Control and Digital Display
Ease of use is another area where this point-of-use tankless water heater excels. The built-in intelligent touch control panel allows users to set and adjust water temperature with precision.
The digital display shows:
- Real-time water temperature
- Inlet water flow rate
- Operational status
This instant feedback gives users full confidence in system performance and allows quick adjustments to suit seasonal water temperature changes.
The intuitive interface makes the unit accessible even for users unfamiliar with tankless water heating systems.
Safety Features and Reliable Construction
Safety is critical for any electric water heater, especially one installed indoors and close to daily-use fixtures. The CAMPLUX electric tankless water heater includes multiple layers of protection designed to ensure long-term reliability and peace of mind.
Key safety features include:
- Overheating protection
- Anti-leakage protection
- Waterproof housing
- Dry combustion protection
- Automatic shutdown in abnormal conditions
- Troubleshooting self-test system
Additionally, the internal water tube is made from 304 food-grade stainless steel, which resists corrosion, reduces scaling, and maintains water quality. This design is particularly beneficial in areas with hard water, where mineral buildup can shorten the lifespan of lesser-quality units.
The unit is CSA approved, confirming that it meets recognized safety and performance standards for electrical appliances.
Installation Requirements and Considerations
Installing this 6kW electric tankless water heater requires proper electrical preparation. It must be connected to a 240V power supply with a 30A circuit breaker and a minimum 12 AWG wire size. Because of these requirements, professional installation by a licensed electrician is strongly recommended unless the installer has sufficient experience.
The heater is hardwired rather than plug-in, ensuring a stable power connection and consistent performance. It should be installed as close as possible to the point of use to minimize heat loss and maximize efficiency.
Water connections use standard 1/2-inch NPT male fittings, making it compatible with most household plumbing systems.
Before installation, users should confirm that the unit’s capacity aligns with their specific water flow and temperature needs.
Ideal Applications and Use Cases
The CAMPLUX tankless water heater electric 6kW is designed primarily for point-of-use applications rather than whole-house heating. It performs best in scenarios such as:
- Kitchen sinks
- Bathroom handwashing sinks
- Office breakrooms
- Laundry room utility sinks
- RVs and tiny homes
- Remote or auxiliary bathrooms
In these settings, the heater provides fast, consistent hot water without the complexity or expense of installing a larger system.
Noise Level and Daily Comfort
Unlike gas-powered heaters or large tank systems, this electric instant water heater operates quietly. The absence of burners, fans, or large moving components results in minimal noise during operation.
This makes it suitable for use in residential kitchens, bathrooms, and offices where noise levels matter. The quiet operation enhances overall comfort and ensures that hot water delivery does not disrupt daily activities.
Durability and Long-Term Reliability
Durability is supported by the use of high-quality internal components and a stainless steel water tube design. The heater is engineered to withstand frequent on-off cycles without performance degradation.
The built-in diagnostic system continuously monitors internal conditions and alerts users to potential issues, helping prevent damage and extending the lifespan of the unit.
With proper installation and electrical support, the CAMPLUX 6kW electric tankless water heater is built for consistent performance over many years of daily use.
