An Open Loop System is for climates where there is no risk of freezing. Recirculation freeze protection can be provided by the Recirculation feature in the controller. An Open Loop Water Heating System provides many advantages. It is the simplest and typically the least expensive active system to install. There is no heat exchanger, which allows efficient heat transfer directly to the water. The system operates at standard line pressure. It is simple to add capacity to the system if demand changes. The system integrates easily with existing systems.
Active closed loop system Closed Loop Solar Heating Systems are suitable for single and multiple solar heating application systems, e.g.domestic solar water heating, solar water heating hot tub, solar swimming pool heating or solar space heating systems. The Closed Loop Solar Systems are suitable for areas with questionable water quality and all climate conditions. The Closed Loop Solar Heating Systems are the preferred option for extremely cold areas.
Specifications:
1) Heat pipe vacuum tube solar collector
2) Wilo hot water pump (RS15/6)
3) Three sensors differential controller
4) Stainless steel pressure storage tank
with one coil exchanger
5) Air vent
6) Electric booster: 1.5kW
7) Expansion tank
8) Pressure gauge
9) Filling and flushing valve
10) P/T valve
11) One way valve
12) Magnetic anode
13) Vacuum valve
Working principle:
1) When the temperature of the heat
collector reaches the set value, the
controller shall start the circulation pump
automatically
2) The circulation pump makes
heat-conducting liquid circulate
automatically
3) The heat-conducting liquid transfers heat
to water by heat exchanger in the water tank
4) In case the temperature of the water tank
does not reach Tmax, then start the
auxiliary heating device
5) In case the temperature of the
circulation pump does not reach the set
value, the circulation pump shall be shut
down automatically
Features:
1) Collector separates with the storage
tank. The tank can be put anywhere in the
house
2) The collector can be put on the inclined
roof or flat place
3) Module design, arbitrary combination,
harmonious with the building perfectly
4) Intelligent control and automatic
operation
5) Anti-freezing: no water inside the tubes
when it works
6) The system controller has the
anti-freezing function that the
temperaturecirculation will
operate while it reaches the fixed
temperature
7) Multifunction: bathing, washing, domestic
heating
8) Workable at anytime and enjoyable
