It consists of an outdoor heat pump unit and an indoor water tank. It absorbs heat from air to heat water, highly energy-saving and safe.

2. Is it more energy-efficient than electric water heaters?

Yes. It produces 3–4 times more heat than it consumes, saving about 60%–75% electricity compared to traditional electric water heaters.

3. Can it work in cold winter?

Yes. Low-temperature models can operate stably even at -15℃~-25℃ and still produce hot water efficiently.

4. How long does it take to heat a full tank of water?

Normally 1–2 hours depending on tank capacity and ambient temperature, faster in warm weather.

5. Is the water temperature stable?

Yes. It maintains constant temperature automatically and provides continuous hot water for bathing, washing and household use.

6. Is it safe to use?

Very safe. No electric heating element inside the water tank, no electric leakage risk, no open flame, no exhaust gas.

7. How long is the service life?

With proper maintenance, it can last 12–15 years, much longer than ordinary electric water heaters.
