Termo+ ground source heat pumps
TERRApump - Ground / Water heat pumps
Heat source: the ground
Ground-source heat pumps exploit thermal energy stored in the rocks or soil. An enormous amount of solar energy that is stored in the soil can easily be used for space or tap water heating. The amount of solar energy that can be extracted from the soil depends on the composition of the soil, on the heat pump capacity, and the manner of the source exploitation (horizontal collector or vertical probe).
The energy is extracted by means water (+ antifreeze agent) which circulates in a closed piping system laid at a depth of 110 – 130 cm (horizontal collector); in case of a vertical probe, the tubular probes are placed into boreholes at a depth of 60 – 140 m. The circulating water transfers heat to the heat pump, which transforms this heat to a higher temperature level (to 55°C) by the help of added electrical energy; the returned water is cooled by approximately 4°C).
Advantages of our ground/water heat pumps:
- Integrated electronic regulation to control the device and to operate the system.
- Incredibly silent appliances with a sound-insulated housing and a twice dampened compressor.
- Elastic mounting of the entire cooling system to the housing (dual anti-vibration mounting of the compressor) decreases the system’s oscillation and noise.
- Compact dimensions of the heat pump.
- A highly efficient and silent Copeland scroll ZH compressor purpose developed for heath pumps.
- An optimised plate evaporator and a condenser made of stainless steel.
- A thermostatic expansion valve.
- A simple and quickly removable cover of the housing enables quick access to the system’s elements.
- Environmentally friendly R 407 C refrigerant.
AQUApump - Water / Water heat pumps
Hea source: groundwater
Ground water is a very suitable energy source for the exploitation with a heat pump. Its main advantage is a relatively constant temperature level (between +7 and +12°C). To be able to exploit ground water we need to drill two boreholes into the ground – one for the extraction of water and one to return the water into the ground. A submersible pump into the extraction well pushes the water through the heat pump, which then extracts thermal energy from the water, and returns it (cooled by a few °C – from 2 to 4) back into the ground through the second borehole, which is about 15 to 20 m away. The amount of water in the borehole must be sufficient for continuous operation even at the highest heat necessities. To extract ground water we need a water permit and a chemical analysis of the water before any work is done. Due to a relatively high
temperature, the ground water is an ideal heat source with the highest energy efficiency (based on the annual average), since it reaches a very high COP.

R - active cooling version
Only active cooling offers genuine benefits. R version heat pumps offer active cooling function. This means that in summer the internal cooling circuit is reversed and actively pumps heat out of the house into the heat sink. So your house stays cool even over long hot periods.
HE - high temperature version
High-temperature heat pumps have a special type of a compressor and refrigeration system which enables the heating of output water up to 65 °C. They are mainly convenient for alteration of existing buildings with radiators. In new buildings, we always choose systems which require lower temperatures of the heating water for cost saving purposes.

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.
