STAFOR COMBI TDHW thermodynamic systems for hot water with built-in water tank
- The refrigerant coil R134a gas circulates through the STAFOR thermodynamic panel where energy is absorbed from the ambient temperature transforming the liquid into a gas and carrying the heat back to the STAFOR COMBI thermodynamic unit. The gas compressed within the system which increases the pressure and therefore also the temperature.
- Simultaneously a water pump pushes water from built in sanitary water boiler into the thermodynamic blocks heat exchanger after which the hotter water returns to DHW cylinder. This flow continues until domestic hot water temperature reaches 55°C. Once this is achieved the system goes into standby.
- Built in sanitary water boiler from SS DUPLEX (DHW cylinder) filled with water is used as hot water source for domestic use. Maximal efficiency and low maintenance costs are achieved with state of art system.
- The system is PV compactible. Inverter can be connected to it which allow starting up thermodynamics when there is an energy excess from photovoltaic panels.
