Coil heat exchange technology
heat energy, and the closed heat exchanger is used to exchange heat and take water. Pressurized water does not need to add booster
pump, and the water quality is fresh without secondary pollution.
20 second rapid heat exchange
exchanger for 20 seconds and quickly turns into hot water. And the temperature difference between the water temperature and the
heat medium after heat exchange is 2 ~ 5 . Moreover, the water quality is fresh, does not contain nitrite and Legionella, is not
easy to scale, and can be used as kitchen water.

Modular design and expandable water tank
Super blue titanium coated heat collector plate
1. The water quality fresh and drinkable
