Energy class when the heat pump is part of an integrated system
Energy class when the heat pump is the sole heat generator. Energy class calculated according to Eco-design Directive 811/2013.
The Thermia Legend is a ground-source heat pump that offers you high annual efficiency thanks to its unique technical solutions. With an impressive seasonal coefficient of performance (SCOP) of 5,24 (Thermia Legend 10 at B0/W35 according to EN14511), Thermia Legend enables you to reduce your energy consumption by up to 75%.
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.
At Thermia, we are committed to healthier lifestyles and reducing our environmental footprint. That’s why Thermia Legend is a ground source heat pump with the more climate-friendly refrigerant R452B and one of the lowest GWP* value – 698. Moreover, thanks to its unique design, it requires a smaller volume of refrigerant than other heat pumps, resulting in a very low C02 equivalent.
The R452B refrigerant represents innovation in every way. It is an excellent heat transfer medium that leads to greater energy efficiency and cost-effectiveness.
* GWP stands for Global Warming Potential and is today the most accurate measure for the assessment of environmental impact level.
Thermia Legend is available in six output sizes: 4kW, 6kW, 8kW, 10kW, 13kW, 17kW, in three-phase version (400V) and in two output sizes: 8kW,10kW single-phase version (230V).
Thermia Legend Duo is a version without a hot water tank that is ready to work with a separate Thermia MBH Legend hot water tank of 200 or 300 liters, or any other hot water tank.
With a wide range of accessories, Thermia Legend can provide also cooling, heat a pool and work in combination with solar panels or additional heat sources.
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:

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.
Control system at a glance:
The “heart” of Thermia Legend is the fixed speed scroll compressor, which makes it extremely efficient, very reliable and quiet.
The compressor of a ground source heat pump is what enables the heat energy extracted from ground or water sources to be raised to a higher temperature for use within a building’s heating distribution system.
Optimum Technology is a technology that constantly monitors your system and adjusts the pump’s performance accordingly. The controller continuously monitors the system and, if needed, automatically adjusts the speed of the circulation pumps to maintain the defined temperature delta for brine and heating circuit. Speed-controlled Class-A circulation pumps guarantee that daily operation is always adjusted according to the user’s requirements and conditions. This means that you can be sure your heat pump is always running at its most efficient level.
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.
Thermia Legend with an optional accessory can also provide efficient cooling for your home during the summer.
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.
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.
Thermia Online is available as an optional accessory.
Thermia Legend 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 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. Thermia Legend is built on 40 years of experience in developing and supplying heat pumps.
