1. Solar energy for central heating. How to prevent overheating
If a system to supply heat to a central heating system has been designed, it will normally provide a lot more heat in summer than is
required only for hot water. In such cases, it is best if the house has a spa or a swimming pool to take best advantage of the heat
in summer, or to install a heat-dissipation device.
2. Metallic components
Always use gloves when handling the various components of the solar collector. We have done everything possible to ensure that
the metallic components are safe to handle, but they may still have sharp edges.
3. Vacuum tubes
Take care when handling the vacuum tubes since they may break if knocked or if they fall. If you need to handle broken glass, always
use gloves.
4. High temperatures
Once the heat pipe is installed in the vacuum tube, if the sun is shining the temperature of the heat pipe condenser may exceed
200ºC/392ºF. At these temperatures, contact with the heat pipe may cause serious burns, so please take the utmost care when
"demonstrating" or "experimenting with" the vacuum tubes and heat pipes. In systems which have already been installed with a net-
work of pipes, if the pump is stopped when the sun is shining, the collector outlet and the pipes nearest the distributor can reach
temperatures of up to 160ºC/320ºF, so take the utmost care when touching them.
