These models use Solaharts proven high performance solar collectors deployed in multiple banks, with parallel connections to central on ground tank installations. The system incorporates a sealed closed circuit system, whereby heat from our special Hartgard fluid is transferred into the potable water.  This means the collectors are protected from frost damage and hard water corrosion.

The hartgard fluid is circulated between the collectors and the storage unit by a fully automatic pump. When the pump is turned off the fluid drains down into the holding tank. The pump is activated by a heat sensor that detects the temperature differential between the collectors and storage vessel. Further, all Solahart central storage systems can be supplied with an auxiliary heating source; either gas or electric.

One of the main features of the Solahart commercial systems are that they are fully manufactured, assembled and pre-tested prior to delivery. The complete system is pre-engineered and supplied in component form, minimising site work. Installations can therefore be completed quickly with a minimum of site labour.
