OEM Heating interface units
Heat Interface Units are used in houses and flats to transfer heat from the district heating system to a decentralised domestic hot water system. These units comprise PHE, control valves, controller, energy meter, pressure relief valve expansion vessel and pumps as if a boiler IWC.
Heat interface units
These units are typically installed in houses and apartment complexes that are connected to a central heating plant or central boiler. Heat is generated and distributed to each residence via a network of pipes.
The heat interface units (HIU) provides a reliable and efficient way to control indoor comfort and produce hot water. Internal (or external) pumps for these circuits must be controlled in order to optimise the conditions of trough heat emitters. This can often only be guaranteed by using a variable-speed pump with an external control signal from the system controller on the unit.
Optimal conditions with a variable-speed pump
The HIU provides a reliable and efficient way of controlling indoor comfort and producing hot water. Internal (or external) pumps for these circuits must be controlled by the needs of the heaters to optimise the conditions. Often this can only be guaranteed by using a variable-speed pump with external control signal from the system controller on the unit.
Externally controlled pump variants
This pump range is designed to be integrated into applications able to remotely control the head and flow, which our program enables in UPM3 UPML UPMXL UPMXXL and UPM3 LIN variants.
