Air-water reversible heat pumps for split installation


The IDOLA H family of heat pumps meets the needs of winter and summer air-conditioning and the production of domestic hot water of small and medium power residential and commercial installations.

It is comprised of an external inverter unit available in various output sizes associated with an internal hydronic unit available in two variants with or without 3kW two-stage (1.5 + 1.5), or 6 kW electrical integration (models 12T and 16T) both equipped as per standard with integrated three-way valve for the production of domestic hot water via external storage tank.

The system is very versatile and able to work at outdoor air temperatures of -20°C and to produce hot water up to 60°C with the aid of electrical integration.

Particularly suitable for use in radiant systems, fan coils, radiators and for the indirect production of domestic hot water (DHW) through an external storage tank (not supplied).

The split cooling circuit avoids the risk of freezing in particularly cold outdoor applications.

The user interface is comprised of a digital remote controller (with a max length of wire of 50 m from the internal unit) equipped with a large screen and simple setting controls.


  • Technical Data

    Characteristics of IDOLA H-UE external unit:

    Reduced inrush current thanks to Inverter technology

    Compressor with twin rotary DC INVERTER motor on rubber vibration damping supports and wrapped in double layer of soundproofing material to reduce vibrations and noise to a minimum

    The compressor is also equipped with crankcase oil heater

    Finned coil made with copper pipes and aluminium fins

    Outdoor air temperature probe already installed on the unit

    DHW storage tank water temperature probe supplied as per standard (mounted by installer)


    Characteristics of IDOLA H-UI internal unit:

    Available with 3 kw electrical integration (IDOLA HI-UI) or without integration (IDOLA H-UI)

    Hydraulic unit with 3-way diverter valve for DHW production supplied as per standard

    Water/gas exchanger with brazed stainless steel plates

    Low consumption system circulator with brushless DC motor

    Automatic air vent

    Water differential pressure gauge

    Water pressure gauge

    Expansion vessel

    Safety valve

    Y water filter supplied as per standard (mounted by installer)


    The control system

    Comprised of a wired-remote digital controller (max 50 m from the I.U).

    HEATING AND COOLING SYSTEM: the compressor frequency is modulated to keep the temperature of the produced water at the established setpoint value. For single-zone systems the control unit can operate as a room thermostat.

    DOMESTIC HOT WATER (DHW) PRODUCTION: upon request of the DHW temperature probe (supplied as per standard), operation is activated in heating mode to maintain the temperature of the DHW tank at the established setpoint value.

    ADDITIONAL ENERGY SOURCES: the electrical integration boiler or booster, if any, can be started in Integration or Replacement of the heat pump and also if the heat pump is not working.

    ANTILEGIONELLA FUNCTION: weekly antilegionella cycles can be set. The heat pump must be integrated with DHW storage tank or boiler electrical heater.

    FAST DHW: this function prioritises DHW by activating all the energy sources available to bring the DHW storage tank to the established setpoint in the shortest possible amount of time.

    SILENCED MODE: according to a programmed schedule, this reduces the maximum frequency of the compressor and the fan speed, to reduce the generated noise and the power absorbed by the unit.

    ON/OFF REQUEST: the unit can be switched on and off by an external contact.

    HEATING/COOLING REQUEST: the unit can be started and stopped in cooling or heating mode by 2 external contacts (e.g. zone thermostat that manages the request for cooling and heating / remote switch).

    ECO: possibility of defining a time slot in heating mode where the heat pump runs with a sliding setpoint defined by the chosen climatic curve. There are 8 climatic curves for low temperature systems (radiant floor) and 8 climatic curves for fan coil or radiator systems)

    WEEKLY SCHEDULE PROGRAMMING: this makes it possible to set a different schedule for each day of the week defining the operating mode for each time slot (COOLING/HEATING/DHW) and the work setpoint.

    Antifrost protection. Guaranteed down to -20°C outdoor air temperature thanks to the heat pump itself. Working in heating mode, for the electric antifrost heater (as per standard) and the electric booster (if installed).
