FAQ
Q1: What is the difference between a tankless water heater and a storage water heater?
A: A tankless water heater does not require a storage tank; it heats flowing tap water directly and instantly, eliminating heat loss from storage and saving space. Storage water heaters require preheating and storing a certain amount of hot water, resulting in heat loss and waiting times.
Q2: How does the device handle low-temperature water input during winter?
A: The product features automatic adjustment for low water temperatures and high-power operation. When low inlet water temperature is detected, it automatically increases heating power to ensure stable and达标 output temperature.
Q3: Are components required to be replaced when switching between LPG and natural gas?
A: Yes, corresponding gas nozzles need to be replaced, and gas source parameters must be adjusted. It is recommended to have this performed by a professional technician to ensure safety and performance.
Q4: Can the heater supply multiple water outlets simultaneously?
A: With a hot water flow rate of 12L/min, it can support one shower and one kitchen faucet simultaneously. For higher flow demands, multiple units can be installed in parallel.
Q5: Are there any special installation requirements?
A: The unit must be installed in a well-ventilated area, connected to a compliant exhaust flue leading outdoors, and inspected by a professional for fuel source, water pressure, and electrical safety.
