EEG

Renewable Energy Act

EEWärmeG

Act on the Promotion of Renewable Energies in the Heat Sector

Efficiency

Ratio between usable heat and supplied energy

EHPA

Umbrella organisation of the EU heat pump industry (European Heat Pump Association)

Emission

Emission of harmful pollutants into the air

Emissions

Combustion products that are released into the air and thus into the atmosphere

Emissions

Substances that are released during the burning of fossil fuel. The objective of the environmental policy is to release as few of these pollutants as possible

Endpoint

When outdoor temperature drops to -15°C, a flow temperature is required at the endpoint to heat the living space

Erdwärme

Wärmeenergie die im Erdreich bis ca. 100m unter der Oberfläche enthalten ist. Kann durch Wärmepumpe als Heizenergie genutzt werden

Evaporator

Ensures evaporation of working fluid to extract thermal energy from it

Exergy

Proportion of energy that can be converted and utilised

Expansion element

Lowers the condensation pressure of the working fluid to the corresponding evaporation pressure. Also controls the injection volume of the working fluid

Expansion valve

Is used to lower pressure in the refrigerant circuit.

Expansion vessel

Absorbs water to compensate the excess pressure during heat-up. When the heating water cools down, it returns water
