Features
-
Efficient performance in all seasons
The Calibra is a ground-source heat pump with inverter technology that offers you superior performance thanks to its unique technical solutions. With an impressive seasonal coefficient of performance (SCOP) of 5.8 (at 35°C floor heating according to EN14825), the Calibra enables you to reduce energy consumption by up to 80%.
SCOP is a measure that describes how efficiently a heat pump works over a full year, including warm and cold periods. It indicates the relationship between the amount of energy produced and the amount consumed. The higher the value, the better the system.
-
Inverter technology
Continuously adjusting the heat pump’s output to current demand, inverter technology means that the heat pump can supply 100% of your energy requirements. This in turn means that there is no need for the user to pay for any auxiliary heating.
-
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.
-
Flexibility
The Calibra is available in two output sizes: Calibra 7 (1.5 – 7kW) and Calibra 12 (3 – 12kW), in both three-phase (400V) and single-phase versions (230V).
The Calibra has built-in 180-liter hot water tank. The Calibra Duo is a version without hot water tank and ready to work with a separate hot water tank: MBH Calibra 200 or MBH Calibra 300, or any other hot water tank. With a wide range of accessories, the Calibra can also provide cooling, heat a pool and work in combination with solar thermal panels or additional heat sources.
-
More hot water, faster
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. Inverter and TWS technology make Calibra the fastest and most cost-efficient producer of hot water in its segment.
Thermia versus other brands in terms of hot water production:
Thermia with TWS technology Typical traditional water heater - 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.
-
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.
-
Touchscreen controller
The new controller in the inverter heat pump boasts a color touchscreen display and user-friendly icons that are easy to understand.
-
New 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 system uses an algorithm that ensures the lowest possible running cost while maintaining the desired indoor temperature.
New features:
- Start-up assistant –step-by-step guidelines for commissioning
- Color touchscreen and intuitive menu
- Full overview of temperatures and curves
- Plug-and-play software update via USB slot
- Interface to BMS (Building Management System) – for the Smart House
-
Low sound level
Innovative mechanical design makes the Calibra one of the quietest heat pumps on the market. Operational sound levels for Calibra 7 vary from 28 dB(A) up to 42 dB(A), depending on compressor speed (according to EN12102 and EN ISO 3741). The Calibra 7 is one of the quietest heat pumps on the market.
-
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 collects heat from the house and deposits it into the ground borehole to provide cooling. That is more cost-efficient than traditional air conditioning. The Calibra with an optional accessory can also provide efficient cooling for your home during the summer.
-
Pool heating
The Calibra 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.
-
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.

The essence of Scandinavian design and durability
Thermia heat pumps are designed, tested and manufactured in one of the harshest climates in Europe. Swedish winters can be extreme. February is usually the coldest month, with temperatures dropping as low as -30°C or even lower in the north and heating is essential from September to May. The Calibra is built on 40 years of experience in developing and supplying heat pumps.
Climate protection begins at home
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.
