Components:

1. Solar collector on sloping roof kit. The connection kit connects the pipe work to the collector
2. Cylinder with solar coil at the bottom and coil for boiler at the top
3. Boiler or other space heating source
4. Hot water out
5. Cold mains water in
6. Pump station used to circulate water from the collector to the user application
7. Controller uses temperature sensors to monitor heat differences between the collector and the water in the tank and switches the pump on or off accordingly
8. Expansion vessel to contain increased water volume in the system due to rise in temperature, and hence increased pressure, or water
