Wintemp Tankless Water Heater Electric 9kW, 240 Volt On Demand Instant Hot Water Heater, Within 1? Stable Temp, Up to 2.2GPM, WiFi Control, ETL Certified, Eco, WM09

Important Note: Before purchasing, please ensure this unit meets your installation requirements. The WM9 model is rated at 9kW (240V) with a maximum current of 37.5A. It requires 1 × 40 Amp double-pole breaker and 1 set of 8 AWG wiring for installation, with 1/2" NPT water connections

Stable Water Temperature: The built-in adaptive chip automatically adjusts heating power based on incoming water temperature and flow rate, ensuring maximum efficiency and delivering consistently comfortable hot water. Provides up to 2.2 GPM of steady hot water with temperature control maintained within ±1°F. Ideal for small sinks, office breakrooms, and other point-of-use or low-flow applications, and can also be used as a booster heater

Energy Saving: This unit uses smart self-modulating technology that automatically adjusts power based on real-time water flow and temperature. When the flow decreases, it reduces energy use—and when no hot water is needed, it goes into true zero-energy standby. The water-electricity separation design helps prevent scale buildup and corrosion, keeping the system highly efficient over the long term with little to no maintenance required

Space-Saving: The WM09 features a compact wall-mounted design, measuring 12.2" (H) × 8.1" (W) × 3.6" (D). It saves over 50% more space compared to traditional tank water heaters and can be easily installed in almost any corner of your home. The upgraded internal layout also makes installation simpler and more user-friendly

Smart WiFi Control: Control the water temperature remotely via the app (compatible with Smart Home and Tuya Smart). Temperature can be set between 86°F and 140°F. The app also monitors real-time water flow and tracks water and electricity usage. The water heater is activated with an electronic switch and operates silently. It features a digital temperature display and an internal cast-aluminum heating system that handles all the heating efficiently

Safe & Reliable: Safety is always WINTEMP’s top priority. The product features multiple safety protections, including leakage protection, overheat protection, and dry-fire protection, and is ETL certified to fully ensure your safety, allowing you to enjoy hot water anytime, anywhere with peace of mind. We also provide a 2-year return and exchange warranty along with long-term professional technical support to give you worry-free use
