Geothermal energy (absorber piles) for heating and cooling buildings

Single-family homes and large buildings of all kinds use precast driven piles in steel-reinforced concrete as absorber piles

		Over 250 installations in operation:

		In over 250 buildings, precast driven piles in steel-reinforced concrete from Nägelebau which are required by the structural design of the building provide heating and cooling resources by extracting energy stored in the ground.

Services from a single source:

ENERCRET GmbH provides the installations required to extract and utilize geothermal energy as a coordinated system. This includes the design, installation and commissioning of all components.

Heat pump:

The heat pump utilizes a virtually inexhaustible resource as vast amounts of energy are stored in the ground and groundwater. This resource permanently regenerates itself through solar irradiation, rainfall and the earth's heat. Every square metre of earth surface is irradiated by approximately 1100 kW of solar energy on an annual basis. The potential is therefore almost limitless. The heat pump utilizes this energy with a high degree of efficiency. One quarter of electrical drive power extracts three quarters of environmental energy. That means: three quarters of the useful heat cost nothing.

Benefits:

	-	The reduced use of fossil fuels such as oil and gas can cut CO2 emissions by up to approx. 75%.

	-	The heat pump needs very little space, which means that the boiler room can be used for another purpose.

	-	Fully automatic and quiet operation.

	-	No oil or exhaust fumes in the cellar.

	-	The cellar temperature is normal as the heat pump does not require any combustion air and does not produce waste heat.

	-	No chimney. No more annual costs for the chimney sweep.

	-	No cleaning and maintenance work.

	-	Simple operation.

	-	Extremely reliable supply as the only extraneous energy required - electrical power - is mains-borne.

	-	The heat pump is not dependent on the unpredictable development of oil supplies and prices.

	-	The systems available today are technically mature products which operate virtually maintenance-free and ensure a long service life.

	-	A solar panel system for domestic hot water is the ideal complement for the heat pump.

	-	Attractive grants from government bodies and power generating companies.

	-	Savings in fuel costs by approx. 3/4 compared to conventional heating systems.
