  • Superior performance all year round

    Superior performance all year round

    The Thermia iTec XT is an air source heat pump that provides maximum performance and functionality across all climate zones in Europe, keeping you warm in winter and cool in summer.

    It has an impressive seasonal coefficient of performance (SCOP) of 4.90 (iTec XT 14 at A7/W35 according to EN14825). The Thermia iTec XT delivers maximum energy savings and performs at temperatures as low as -30°C.

    *SCOP (Seasonal Coefficient of Performance) specifies how efficiently a heat pump works throughout the whole year, including both warm and cold seasons. The higher the value, the better the system.

  • Beautiful Scandinavian design

    Beautiful Scandinavian design

    The iTec XT has a new, very high quality  display. As well as enhancing the overall design, the new display also provides improved contrast. The controller for the iTec XT heat pump features user-friendly icons that are easy to understand and use.

    The iTec XT indoor unit has a clean, white front and the outdoor unit is equally elegant with a matt black finish.

    All the different indoor units have a clean Scandinavian design with a white front, which will fit discreetly into your home.

  • Versatility


    An air source heat pump has two parts: the heat pump itself, which is installed outdoors, and an indoor unit controlling output, hot water supply and other features.

    The Thermia iTec XT is available in three output sizes: iTec XT 10 (3-10kW), iTec XT 14 (3-14 kW) and iTec XT 16 (3-16 kW) for both single phase (230V) and three-phase (440V) installation.

    For the indoor unit you can choose five versions: Standard, Plus, Total, Total EQ and Total Compact, depending on your requirements.

    The iTec XT allows you to combine the volume tank and the hot water tank if you so desire. The combinations are endless, allowing us to tailor your heating system to your needs, while keeping your energy costs at a minimum.

    On top of this, the iTec XT comes with a wide range of extensions, e.g. for heating the pool, working in combination with solar panels or additional heat sources and other options.

  • Let’s be more eco-friendly

    Let’s be more eco-friendly

    At Thermia, we are committed to healthier lifestyles and to reducing our environmental footprint. That’s why our air source heat pumps now use the more eco-friendly R32 refrigerant.

    The R32 refrigerant represents innovation in every way. It is an excellent heat transfer medium that leads to greater energy efficiency and cost-effectiveness. R32 also has low global warming potential (GWP), making it friendlier to the environment.

  • Cooling as standard

    Cooling as standard

    The Thermia iTec XT can also provide efficient cooling for your home during the summer. The processthat provides heat during winter is simply reversed to cool in summer.

    All iTec XT models offer this function as standard.  

  • Low sound level

    Low sound level

    With a sound level of 42db(A) at 4 meters distance, the Thermia iTec XT is very quiet. Thanks to its excellent acoustic performance, the outdoor unit can be placed wherever is most convenient without worrying about noise affecting your neighbors, for example.

    In air source heat pumps, noise is produced by the operation of both the compressor and the fan. Operational sound levels for the iTec XT vary from 42db(A) up to 58db(A), depending on compressor and fan speed (according to EN12102).

  • Reduce your energy bill

    Reduce your energy bill

    The iTec XT air source heat pump features the Thermia-developed inverter technology, which controls the compressor and constantly adjusts the heat load according to current heat demand.

    On top of this, the Thermia Optimum technology monitors your system and adjusts performance accordingly. Speed-controlled

    Class-A circulation pumps guarantee that daily operation is automatically adjusted according to the conditions and your requirements. Thus, you never use more energy than needed, keeping your energy bills to a minimum without lifting a finger.

  • More hot water, faster

    More hot water, faster

    The hot water tank is equipped 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 greater due to the high initial temperature


  • Super easy to control

    Super easy to control

    Thermia heat pumps work with complete precision to give your home the best possible indoor climate at the lowest possible cost. Once the heat pump is set, you never need to think about it again. Most functions are automatic, unless you want to change the settings or manually control the system.

    The Thermia iTec XT comes with the latest display technology, which gives you a very friendly user interface with attractive icons and high contrast. It displays visualized heat curves and raising or lowering the temperature can be achieved at the touch of a button.

  • Demand-controlled defrosting

    Demand-controlled defrosting

    When operated in winter, an air source heat pump extracts energy from the cold outside air and releases the heat into the living space. Under certain outside air conditions, when the pump is operating in heating mode, frost can form on the air-cooled heat exchanger, decreasing heating performance. Defrosting an air source heat pump is essential to ensure the functionality of the system. However, defrosting consumes energy and should only be performed when, and for as long, as needed.

    In standard systems, a typical defrosting cycle is based on a timer function. In contrast, Thermia’s defrosting of the outdoor unit is automatic and demand-controlled. It is only activated when needed and only for as long as necessary. This minimizes the energy consumption required to keep the outdoor part of the system free of ice. The result is improved annual efficiency.

  • 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.

  • Thermia Online

    Thermia Online

    The Thermia Online app enables you to operate your heat pump remotely. This means you can check 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 also provides installers with comprehensive diagnostics data andenables 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.

    Thermia Online is available as an optional accessory.

  • Pool heating

    Pool heating

    The Thermia iTec XT can easily be extended 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.

  • The essence of Scandinavian durability and functionality

    The essence of Scandinavian durability and functionality

    Thermia heat pumps are tested in one of harshest climates in Europe. Swedish winters can be extreme. February is usually the coldest month, with temperatures regularly below zero, and heating is essential from September to May. As a true Viking, the Thermia iTec XT has been proven and tested in the cold Nordic climate and features a variety of functions that can provide the perfect level of comfort for your home, throughout the year and for years to come.

Enjoy the benefits of renewable heating and cooling

Enjoy the benefits of renewable heating and cooling

The Thermia air source heat pump operates on a simple principle: it transfers energy from the ambient air to the water in your heating system via a refrigeration process. The energy stored in the air is simply extracted and can be used for heating, cooling, domestic hot water and pool heating.

During the winter, air source heat pumps can heat your home via floor heating or radiators. In the summer, they provide pleasant cooling via a floor system or fan coils. You can enjoy hot water all year round and also heat your pool.
