Heat Storage with Coil - HSC
Solar thermal system allows you to use several types of heat store depending on your needs.
-
Pressurized heat store:
In this case, the pressurized water flow through the heat store and the tap water is preheat from the solar circuit. The water from the solar circuit flow through a pipe heat exchanger which transfers the heat from the solar circuit to the heat store.It is also possible to insert a separate pipe heat exchanger to transfer heat for space heating. -
None pressurized heat storage:
In this case, pressurized water flow through a large pipe heat exchanger so that the water will be preheated. The solar circuit, circulate water from the solar collector into the heat storage and back to the solar collectors.
The heat stores will achieve high temperatures and they should be well insulated.
The dimmention of heat storage should be between 50-100 liters / m2 of panels. 50 liters provide a low investment, while 100 liters allow higher energy yield and lower costs per KWh over time.
We work with OSO hotwater for optimized heat store, high quality and proper function.
It is also possible to use other types of heat stores made in plastic, concrete, with PCM or in the form of storage in a borehole.
