| Drainback DB Systems |
The “DB” System Provides a reliable method for ensuring that the collectors and their pipelines never
freeze. This is done by removing all the water from the collector(s) and piping when the system is not
producing heat. Freeze protection is provided when the system is in the drain mode. Each time the pump
shuts off the water in the collector(s) and piping drains into the insulated reservoir tank. To allow for complete
drainage the collector(s) and piping are mounted at a slight angle. A sight glass attached to the reservoir
tank shows when the reservoir tank is full, indicating that the collector(s) has been completely drained.
The differential control of the “DB” System activates the pump using the same strategy as the “D” System.
The solution, distilled water or antifreeze, circulates in a closed loop never coming in direct contact with the
potable water in the storage tank. The closed loop includes the collector, connecting piping, pump, reservoir
tank and heat exchanger. The heat exchanger wraps around the perimeter of the storage tank heating the
potable water in the tank.
The "DX" drainback system works on the same principle as the "DB" drainback. The major difference being,
the heat exchanger is integrated into the drainback tank. This type of drainback tank can be retrofitted to
existing water heaters.

| Indirect "I" Systems |
The “I” System is designed to accommodate climates where freezing weather occurs more frequently.
Instead of water flowing through the collector, an antifreeze solution is circulated. A heat exchanger is located
within the storage tank. This maximizes the heat transfer from the antifreeze solution to the coldest water in
the storage tank.
The “I” System is known as an indirect pumped system because the heat transfer solution, I.e. antifreeze, is
pumped through the collector in a closed loop. It never comes in direct contact with the potable water in the
storage tank. The closed loop includes the collector, connecting piping, pump, expansion tank, and heat
exchanger. In this design, the large heat exchanger coil wraps around the perimeter of the storage tank.
As in the “D” System, the differential control determines when the pump should be activated and deactivated.

| Indirect "IPV" Systems |
The “IPV” System is similar to the “I” System except that the energy needed to power the pump is provided by
a photovoltaic (PV) panel. The PV panel converts sunlight into electricity, which powers a DC pump. The
transfer fluid circulates through the system only when the sun is shining.
The DC pump and PV are suitably matched to ensure optimum performance. The pump starts when there is
sufficient solar radiation available to heat the thermal collector. The pumping speed increases with the
increase in the amount of sunlight. This produces a flow rate matched to the level of heat transfer required.
The system then shuts off when the available solar energy diminishes.
