Larger heating constructions

The solar panel system consists of:
- Plate heat exchanger (delivered separately)
- Solar panel with fittings
- Steering unit (with sensors)
- Pump
- Water tank / heat storage
- Pipe parts for connecting the solar panel circuit


1. At the upper part of the plate heat exchanger and in the lower part of the solar panel, there are sensors (S2 and S1), which determine when the steering unit must supply electricity for the solar panel pump (P1), to start heating the water. The pump starts when S2 and S1 feels that the temperature in the heat storage is lower than in the solar panel.

2. The water is pumped through its own pipe system from the bottom to the top of the panel. The solar panel has a green house effect and heats the water as it moves along. The hot water exits at the top of the panel and pours back into the heat storage. The hottest water will lie on top of the heat storage, because hot water rises, while cold water sinks.

3. The solar panel is connected to a pump station which consists of a pump, plate heat exchanger, control unit with sensors, and a 150 litre water tank.


Term overview
- Solar panel module: The main component in a solar panel area.
- Heat storage: A water tank which holds hot water from the solar panel.
- Steering unit: A differentiating thermostat which starts the solar panel pump.
- Plate heat exchanger: A unit which transfers heat energy between two fluids with different temperatures without mixing them.
- Solar panel circuit: The pipe system leading from the heat storage, through the entire solar panel and back into the heat storage again.
- Circulation pump: A unit pumping water from the tank, through the solar panel circuit.
