Solar heating
To save energy solar heating is an ideal solution and ecologically is the most acceptable comparing to other heating systems. Great numbers of sunny days results a great efficiency of system and in average has a saving of a 50% - 60% of annual needs for energy. In summer period a solar heating is ideal for warming up sanitary water because the classic heating system can be shut down and we can remove a harmful transmissin of burning gases. Practice has proven that:
- Solar collector annualy saves 750 kWh energy by 1m2
- In summer period system satisfy 90 - 100% needs for hot water
- In crossing period system satisfy 50 - 70% needs for hot water
- In winter period system satisfy 10 - 25% needs for hot water
Solar heating has a very simple work principle. Number of collektors is calculated before installing on roof. Hot air generated by these collectors is fan forced through an air-to-liquid heat exchanger with the sanitary water being pumped through the liquid section of the exchanger.
The heated water is then circulated through the storage tank in a similar fashion to the liquid collector system. As an alternative in periods without sun boilers can have an electrical burner or oven. Automaticaly regulation is also necessary so that all could work properly.
