Pressure Series
Pre-heated Solar Water Heater(QJF-E/ QJF-EH)

Work principle:

One copper coil is installed inside the tank as the heat exchanger. When water flows into the copper coil, it absorbs the heat of the water in the tank via the copper coil therefore the water tank is just a heat storage tank.

Advantages:

1. Heat exchange instantly, water plentiful.
2. Fresh water quality, live water supply
3. Work with pressure, output with riptide
4. Temperature invariableness, comfortable and safety
5. Hot & cold separate, never breakage
6. Energy storage, anti-freezing
7. Working with intelligent, easy and reliable
8. Perfect pursuit
