solar heating system - KD-SPA

solar heating system:

Split Pressurized System

Split pressurized solar water heater is composed of heat pipe, evacuated tube solar collector, pump station (including circulation pump, controller, expansion vessel, pressure gauge, sensors etc) and pressurized water tank.

Working principle:

When the temperature of the heat collector reaches the set value, the controller shall start the circulation pump automatically. The circulation pump makes heat-conducting liquid circulate automatically. The heat-conducting liquid transfers heat to water via heat exchanger inside the water tank. In case the temperature of the water tank does not reach the set value, then the auxiliary heating device will be started. In case the temperature of the circulation pump does not reach the set value, the circulation pump shall be shut automatically

Features:
1)Collectors are separated from the storage tank, so the tank can be put anywhere around the house.

2)The collectors can be put on the inclined roof or flat place

3)Module structure, easy combination, harmony with the building perfectly
4)Intelligent control and automatic operation
5)No worry about being frozen because there is no water running inside the tubes when working
6)The system controller will start the at the set value so as to prevent the system from freezing
7)Workable at anytime and enjoyable multifunction
8)Hot water center for bathing, washing and domestic heating
