  • Inverter technology

    Inverter technology

    Thermia iTec is an air-source heat pump with inverter technology. The inverter-controlled compressor constantly adjusts the heat load according to the current heat demand. You never use more energy than is needed, further reducing your energy bills.

  • Efficient performance in all seasons

    Efficient performance in all seasons

    With an impressive coefficient of performance (COP) of 4.72 (iTec 5 at A7/W35 according to EN14511), Thermia iTec delivers maximum energy savings. COP is a measure of heat pump efficiency and indicates the relationship between the amount of energy produced and the amount consumed. The higher the number, the better the system.

  • Heating


    Most common European heating systems are water-based, with heat being distributed via radiators or hydronic floor heating. The output temperature of the water distribution system is usually 30-35°C for floor heating and 45-55°C for radiators. Thermia heat pumps offer a low-carbon alternative to traditional boilers in modern buildings, whether for new-builds or refurbishments and regardless of the temperature required in the heating system.

  • Cool in the summer

    Cool in the summer

    The heat pump provides heat during the winter while in the summer the process can be simply reversed. The heat pump now collects heat from the house and – via a refrigeration process and compressor (the same technology used in your refrigerator) – removes it to provide cooling. In this way, iTec can also provide efficient cooling for your home during the summer.

  • More hot water, faster (with iTec Total indoor unit)

    More hot water, faster (with iTec Total indoor unit)

    The hot water tank is fitted with our TWS (Tap Water Stratification) technology, which means that hot water is produced faster and at higher temperatures than with traditional technology. Because the hot water is diluted to tap water temperature, the volume of usable hot water is considerably higher due to the high temperature.

    Thermia versus other brands in terms of hot water production:

    • Recharging from 40°C to full load for a water heater using TWS technology: just 21 mins.
    • Recharging from 40°C to full load for traditional water heater: 50 mins.
    • Time to fully recharge tank after peak consumption: 21 mins.
    • Time to fully recharge tank after peak consumption: 50 min.
  • Intelligent control system

    Intelligent control system

    The controller coordinates and controls the heating system. Thermia heat pumps work with complete precision to give your home the best possible indoor climate at the lowest possible cost. Our controller is very easy to use.

    The controller displays visualized heat curves and, once it is set, you never need to think about it again. Raising or lowering the temperature can be achieved at the touch of a button.

  • Optimum technology

    Optimum technology

    Optimum Technology is a technology that constantly monitors your system and adjusts the pump’s performance accordingly. Speed-controlled Class-A circulation pumps guarantee that daily operation is always adjusted according to the user’s requirements and conditions. That means you can be sure your heat pump is always running at its most efficient level.

  • Flexibility


    Thermia iTec is available in three output sizes: 1-5 kW, 2-9 kW and 4-16 kW in both three-phase (400V) and single-phase versions (230V). It consists of two parts: the heat pump itself, which is installed outdoors, and an indoor unit. You can choose from four versions of the indoor unit: Standard, Plus, Total Compact and Total, each with different features. The choice of unit is tailored to the set-up of your heating system, ensuring that you never pay for more than you actually need.

  • Low sound level

    Low sound level

    Acoustically engineered design makes iTec one of the quietest heat pumps on the market. Thanks to its excellent acoustic performance, the outdoor unit can be placed wherever is most convenient without worrying about sound affecting your neighbors, for example.

  • Thermia Online

    Thermia Online

    The Thermia Online app enables you to check that your heating system is working properly, reduce the temperature when you are on holiday, or receive a notification if anything unexpected comes up. Our online system provides installers with comprehensive diagnostics data and also enables them to respond promptly to notifications or access a live feed on system performance. The Thermia Online app is available for both Android and iPhone.

  • Pool heating

    Pool heating

    iTec can easily be supplemented to heat your pool, all year round. In this way, you can enjoy your pool in all seasons while substantially reducing the cost of heating it.

Low-carbon heating is the key to sustainable development

Air and ground source heat pumps have the potential to reduce your home’s CO2 emissions by up to 75% and can act as your individual contribution to the commitment to source 32% of European energy from renewable sources by 2030
