FUJITSU WATERSTAGE High Power series (11 - 16 kW)
High power models realizes high heating capacity and high efficiency by newly developed "Linear Control Injection Technology" and "Co-axial Heat Exchanger". These properties are the key for a reliable heating operation throughout the whole year even in a strong winter.
Energy efficiency is improved by the linear Control Injection Technology and the optimization of refrigerant
cycle control. High power model realizes high performance and high efficiency by adopting twin sensors and control technology corresponding to hot water heating.
High leaving water temperature 60°C kept down to -20°C outdoor temperature without using backup heater.
Improved operation range down to -25°C outdoor temperature.
Keeping the rated heating capacity up to -7°C outdoor temperature.
TWIN ROTARY COMPRESSOR with Linear Control Injection port.

Heat pumps - heat from nature
Heat pumps are the first choice for those who want to lower their heating bills and generate heat in a more environmentally responsible way. After all, the environment provides the heat pump with an unlimited and free supply of the energy it needs. This fully-fledged heating system needs very little power for its drives and pumps in order to make this energy available. A heat pump makes you independent of fossil fuels, and in addition, actively contributes towards reducing CO2 emissions and protecting the climate.
Simple principle, great result
A heat pump works in a similar way to a fridge – simply the other way round.
In a fridge, heat is transferred from the inside to the outside. With a heat pump, this happens exactly the other way round. Heat from the air or the ground is transferred into the living space via the heating system. Vapour from a refrigerant is compressed to increase the temperature, to make it high enough for central heating and DHW heating.
Renewable energy from ambient heat
Heat pumps use ambient heat from the water, ground or air. This ambient heat is stored solar energy or geothermal heat from below ground. Ambient heat is therefore a renewable energy, of which we have an inexhaustible supply.
Unlike fossil fuels, renewable energies have the big advantage of being able to be regenerated. In addition, ambient heat is a decentralised energy supply, which is available at all times and which can be used without the need for complex supply systems or energy monostructures.
Use with various energy sources
The best heat source for each individual case depends on local conditions and the actual heat demand. Heat pumps can use various energy sources:
- Air – practically unlimited availability; lowest investment costs
- Ground – via geothermal collector, geothermal probe or ice store; very efficient
- Water – extremely efficient; observe water quality and quantity
- Waste heat – subject to availability, volume and temperature level of the waste heat
Advantages of heat pumps
60 to 75% lower heating costs
Heat pumps obtain 3/4 of required energy free of any charge, from the environment in which you live. Soil, groundwater, and outside air store huge amounts of thermal energy which can be transformed into heating energy using heat pumps. The savings are considerable compared to other conventional heating systems. The amount of power consumed by heat pumps is notably lower than the amount of heat they generate.
Smart future investment
If you decide to install a heat pump today, you should be aware you are making an investment for the future. Its true value lies in many measurable and nonmeasurable aspects. In addition to the safety of investment, flexibility, low heating costs, comfort, and many economic and ecological benefits, a heat pump is actually an investment in your future and the future of your children.
New building, refurbishment, or heating system replacement
A heat pump is an ideal solution for heating and cooling of newly constructed or refurbished buildings, or when replacing an existing heating system. Since it operates on the principles of low-temperature heating, it is suitable for both underfloor heating and heating with wall-mounted radiators, as well as a combination of both. Heat pumps are also appropriate for rebuilt or refurbished buildings with radiator heating since new high temperature heat pumps can reach water temperatures of 80°C.
Warm in the winter, cool in the summer
Unique heat pump technology allows your heating system to heat your home during the winter and cool it during the summer without additional work or investment. The heat pump system can be used for cooling regardless of whether you use fan coils or underfloor heating.
