SOLAR HOT WATER STORAGE TANK
The eco-SPARK
®
system can be installed as an open or closed loop system and circulates the water in the
storage tank. The system is in installed on the feed line to the current conventional heating system. The feed
enters the storage tank. The storage tank accumulates energy according to the performance of the collectors
and user demand.
Important!
System MUST be designed by a professional engineer.
1.
Fresh water feeds into the lower part of the solar storage tank at grid pressure whenever there is
demand.
2.
Water enters from the lower part of the storage tank to the heat exchanger according to
temperature difference which is detected by the controller. The heat exchanger's energy is supplied
by the solar system.
3.
Heated water from the heat exchanger flow through the upper part of the storage tank.
4.
Heated water flows out of the storage tank into the auxiliary heating system whenever there is
demand.
5.
Solar system – closed loop system provides hot water (heated by the sun) to the heat exchanger,
where the heat is transferred to the feed water. The solar system can be operated by a differential
controller with temperature sensors or just a pump with a timer.
6.
Differential controller operates the system according to temperature sensors.
7.
Water enters the heat exchanger for complimentary heating by conventional heating methods.
8.
Water exits from the heat exchanger at the required temperature (preset).
9.
Conventional heating system (based on gas, diesel, electricity etc').
