The Camplux 11kW Tankless Water Heater requires a dedicated 240V electrical supply to operate.
We selected this model for our review because it offers a compact wall-mounted design that provides hot water in three seconds. For a tankless water heater, verifying your electrical capacity is critical because these units draw significant power instantly to heat water on demand, which can trip breakers or overheat wires if the circuit is not sized correctly. You must ensure your electrical panel has sufficient total capacity to support the 11kW load alongside other heavy appliances in your home. Because of the high wattage, you should also confirm the required distance between the unit and the panel to prevent voltage drops that could hinder the heater’s ability to reach the desired temperature of 86F – 125F.
What to Check Before Buying the Camplux 11kW Tankless Water Heater
Before purchasing, you must verify these electrical and site requirements with a qualified installer to ensure the unit functions safely and meets local regulations.
- Confirm your electrical panel can support a dedicated 240V circuit for an 11kW continuous load.
- Verify the correct wire gauge is used to prevent overheating and melting of the electrical feed.
- Check if your local building codes require specific permits or inspections for high-voltage water heater installations.
- Determine if the installation requires a hardwired connection to the breaker or a specific heavy-duty outlet.
- Confirm the required conduit type and mounting hardware for the electrical feed to meet safety standards.
Understanding the Camplux Tankless Heater and Alternatives
The Camplux Tankless Heater is a point-of-use water heater, which is a small device that heats water instantly as it flows through the unit rather than storing it in a large tank. This specific type of heater is ideal for small spaces like under-sink installations or RVs where space is limited. If you require a higher flow rate than the 0.52 GPM provided by this model, or if you need to supply multiple fixtures simultaneously, you may need to look at larger commercial-grade units or high-capacity residential systems. These larger alternatives are designed for high-volume flow and heavy-duty heat exchangers, whereas this model is designed for localized, immediate use.

If you need a compact, space-saving solution for a single point of use and have access to a 240V circuit, the Camplux 11kW Tankless Water Heater is a suitable choice. However, if your property lacks 240V infrastructure or requires a higher flow rate for multiple bathrooms, you should consider a larger system or a different fuel type.
