More than 22 years of experience and far more than 30,000 completed heat pump projects – from single family detached houses to an office building with a usable floor area of more than 10.000 sqm – make TEMRO SHOP the one of the leader in the utilization of geothermal energy. Tailor-made and efficient heat pumps solutions are our strength, energy savings our goal! Renewable energy directly supplied from the ground beneath a building is one of the most sustainable ways of long-term energy usage.


The earth is a huge energy storage system, which permanently regenerates through solar radiation. Every square metre of our earth receives a quantity of more than 1,000 kWh of solar energy yearly. Due to this amount of heat, constant temperature levels averaging 10 to 12° Celsius prevail all over the year in Central Europe in the earth from a depth of approximately 10 metres, and this temperature rises by 1° Celsius per each 33 metre of depth. It is quite simple and very cost-efficient to use the heat stored within the ground for heating purposes. About 80% of the required heating energy can be extracted from the ground by means of heat pumps, the remaining 20% we use, in form of electric power, for operation of the heat pump.


As a result of heat extraction during winter, the temperatures of the ground decrease. Due to this much-appreciated side effect, the ground may virtually be used for free for cooling purposes during summer.




Irrespective of the size of the project, our focus is always set on the design and implementation of an efficient and energy-saving heat pump solution. A perfect heat pump solution is the result of early stage expert consultation provided to the client combined with the compilation of all essential data regarding climate, ground conditions, building and occupant requirements. This data is essential in order to produce a reliable heat pump solution as well as the results of the simulation calculations we use to determine the economically usable energy supply of the earth.


By careful calculation and selection of heat pump components - from exchangers, compressors, expansion valves and circulation pumps – we are able to provide significant savings on initial capital costs and annual operating costs. Due to our considerable experience and confidence in our systems we are able to offer extended warranty periods.


The same rule applies: experience is everything. The concept - actually simple – does however quite often lead to unsatisfactory results if the overall design and the simulation are not made by experienced specialists. Heat pumps that are designed without adequate experience, are frequently over dimensioned and consequently inefficient. Our clients will however profit by our twenty years of experience in the implementation of efficient and economic projects.

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.
