Page 30: Functioning
DS-matic 3 FUNCTIONING The DS-matic automatic solar heating system is an appliance designed to make maximum use of solar energy. Its operating principle is based on the liquid in the solar circuit being heated in the solar collector, and the absorbed heat then being exchanged with the domestic hot water in the hot water tank. - Page 31 Avantages du DS-matic The DS-matic automatic solar heating system has the following advantages as compared to traditional solar heating systems with a pressurised solar circuit: 1. Its compensation system drains all the water from the solar collectors when it does not require energy from them.

Page 36: Inhibitor Liquid
DS-matic The resistance and heat transmission of DOMUSA TEKNIK inhibitor liquid make it suitable for use in solar heating installations. Its main function is to protect the various components of the installation from corrosion, as different metals are used. DOMUSA TEKNIK recommends using a minimum concentration of 30% of inhibitor liquid. -
Page 37: Ds- Matic Configuration
DS-matic is the ideal solution for combining with boilers or heaters producing domestic hot water. The domestic water is heated up in the solar accumulator and conveyed to the cold water inlet of the boiler. The water is pre-heated before entering the boiler, to provide a suitable temperature for the hot water even if the burner is not ignited or is functioning on a lower setting. -
Page 38: Location
It is very important to choose a correct location for the solar collectors, as an unsuitable location can reduce the system’s efficiency: wrong orientation, shadows cast on the solar collector, etc. DOMUSA TEKNIK recommends taking the following indications into account when choosing a location: 1. - Page 39 If other tube diameters are used it cannot be guaranteed to work properly, and there may also be risk of noise on functioning.
