Termix VMTD-IV

Application
The fully insulated Termix VMTD-IV is a complete solution with a built-in water heater and a differential pressure controlled heating system. Termix VMTD-IV is applicable for single family houses and for decentralized systems.

District heating (DH)
The substation is prefabricated with a differential pressure controller, a fitting piece and a sensor pocket for insertion of a heat meter as well as strainer and ball valves.
​​​​​​​
Heating (HE)
The heating circuit is designed for direct generation of heat. The differential pressure controller sets the optimum operation conditions for radiator thermostatic valves enabling individual temperature control in each room.
​​​​​​​
Domestic hot water (DHW)
The domestic hot water is prepared in the heat exchanger and the temperature is regulated with a flow-compensated temperature controller with integrated differential pressure controller. The DH water is cooled very efficiently by the heat exchanger, thereby creating an excellent operating economy. The Danfoss IHPT valve ensures a stable domestic hot water temperature by varying loads, varying supply temperatures and by high and varying differential pressure without the need for readjusting the valve. This protects the heat exchanger against overheating and lime scale formation. Furthermore the IHPT valve has an integrated idle temperature controller, which keeps the house supply line warm. This shortens the waiting periods during summer when the heating system is in reduced operation, which is ideal where high comfort is requested.

Options
The Termix VMTD-IV can be supplied with a DHW recirculation pump, and DHW recirculation safety valve. The secondary heating pipes can be either top or bottom connected.
​​​​​​​
Insulation
The Termix VMTD-IV comes complete with a fully insulated cover thus minimizing the heat loss both during tapping of domestic hot water but also when only space heating is required. The connections are made by nuts and gaskets.
