Key Features High-quality Materials: Brass, ABS, and cast aluminum will not easily rust, crack, or release harmful substances, and can be used safely for a long time. Fast Heating: The tankless design, and strong power (5000W) make the water heated in 30 seconds without waiting too long while ensuring large water production (up to 26.42gal/H). You can instantly get the warmth of hot water in the cold winter. Intelligent Constant Temperature: The internal intelligent chip will quickly match the heating power required for bathing based on the inlet temperature, outlet temperature, and water flow. Accurate temperature control of ± 32.9 ℉ frees you from the suffering of enduring sudden changes in temperature. High Security: It has leakage protection, anti-dry burn protection, over-temperature protection, automatic power-off function, IPX 4 waterproof level, and power-on temperature self-test function.
