HIU - HEAT INTERFACE UNIT
HIUs (heat interface units) are thermal-hydraulic units that allow autonomous management of the heating system and the production of domestic hot water of the utilities in central heating systems.
They are typically installed in residential complexes with many housing units, where it is necessary to exploit the thermal power made available by a shared heat generator.
Heating is managed and brought to the individual apartments thanks to a connection between the
building’s heat generator and the individual houses that are managed individually thanks to the HIU module.
These modules therefore provide the most compact, complete and efficient solution in this context:
- utilities served directly by small district heating networks without the interpositon of substations;
- centralized systems that exploit the power produced by a thermal power plant able to draw from different energy sources.
So HIUs combine the benefits in terms of energy efficiency and easy of maintenance of a centralized system with the freedom of autonomous management of the typical thermo-regulation of a domestic boiler. HIUs are also predisposed for the accounting of thermal and water user consumptions.
The range of NOVAHIU products is divided into 5 types, depending on the different market demands, with the possibility of managing heating and domestic hot water production in different design configurations.
The NOVAHIU V2 module manages the technical water for the heating circuit and domestic hot water in an indirect way.
The NOVAHIU V2 module, in addition of the different product size (from 22 kW and 32 kW), is in turn divided into Basic and Premium versions. In this last version (compared to Basic one) are added a PV valve to control the differential pressure on the primary circuit, and a thermostatic valve to control the temperature on the supply circuit to the apartment heating.

The Product
The NOVAHIU V2 module was born as a thermal-hydraulic unit for heating in apartment complexes in which a thermal power plant is present. The modules allow users to connect and access central heating instantaneously and reliably during all hours of the day.
Thanks to these modules, heat is distributed uniformly from the building’s centralized heat generator directly to each individual apartment based on need. In this way, water heating is controlled efficiently and reliably.
The NOVAHIU V2 modules therefore have the following functions:
- Heating zone management;
- Sanitary accumulation management;
- Preparation for accounting;
- Security features.
The module is supplied as standard with Grundfos UPM3 Hybrid circulator, ErP-Ready.
The NOVAHIU V2 module acts as a bridge between the central boiler system and the individual heating systems of each dwelling. The production of DHW is not foreseen, but connections are provided for a supply circuit of a sanitary storage tank.
The plate heat exchanger separates the primary and secondary circuits.
