Termix VMTD-F MIX-I

Application
The Termix VMTD-F MIX-I is a complete solution with built-in water heater and heating system with differential pressure control and mixing loop. The Termix VMTD-F MIX-I is applicable for for single-family houses and for decentralised systems in multi-family houses.

District heating (DH)
The substation is prefabricated with a differential pressure controller, fitting piece and sensor pocket for insertion of a heat meter as well as strainer and ball valves. Furthermore the substation is delivered with a mixing loop including pump, controls and non-return valve.
​​​​​​​
Heating (HE)
The heating circuit is designed for direct connection. The differential pressure controller sets the optimum operation conditions for radiator thermostats in order to enable individual temperature control in each room. The mixing loop creates a suitable temperature level e.g. for floor heating. In order to enable a time-dependent temperature control program, a zone valve with actuator and a room thermostat can be included as an option.

Domestic hot water (DHW)
The domestic hot water is prepared in the heat exchanger and the temperature is regulated with a thermostatic control valve. The patented sensor accelerator accelerates the closing of the thermostatic control valve which protects the heat exchanger against over heating and lime scale formation. The sensor accelerator and the control valve also work as a bypass keeping the house supply line warm. This shortens the waiting periods during summer when the heating system is in reduced operation. The sensor accelerator helps to ensure a stable DHW temperature by varying loads, flow temperatures and differential pressure without the need for readjusting the valve.

Options
The substation can be supplied with a built-in non-return valve and safety valve mounted in the cold water supply. The substation can also be supplied with a thermostatic circulation valve.
