About Renewable Energy

Variable Refrigerant Flow System

Renewable energy is sustainable energy that comes from the natural environment.

We can obtain it from the sun (solar energy), from the water (hydropower), from the wind (wind turbines), from hot dry rocks, magma, hot water springs (geothermal) and even from animal manure, crop residues and waste (biomass).

Renewable energy sources are environmentally-friendly because they don’t bring CO2 emissions and climate change.

The amount of the energy captured by heat pump is considered to be a renewable energy, since aerothermal, geothermal and hydrothermal heat energy is used in heating / cooling and hot water supply.

Even at temperatures we consider to be cold, air, ground and water contain useful heat that's continuously replenished by the sun. By applying a little more energy, a heat pump can raise the temperature of this heat energy to the level needed.

Heat pumps as renewable energy source ~ EU RES-Directive and Heat pumps ~

Heat pumps use renewable energy sources, namely energy found in the air (aerothermal), ground (geothermal), and water (hydrothermal). In the EU RES-Directive the European Commission and Parliament documents measures for promoting the use of renewable energy resources (2009/28/EC) .

EU RES-Directive
Renewable energy sources covered by Directive

  • Wind
  • Solar energy
  • Geothermal energy
  • Aerothermal energy
  • Hydrothermal energy
  • Ocean energy
  • Hydropower
  • Biomass
  • Landfill & Sewage treatment plant gas
  • Biogass

“aerothermal energy” = heat in the ambient air
“geothermal energy” = heat beneath the surface of solid earth
“hydrothermal energy” = heat in surface water

Heat pumps, as well as PV or Solar water heater, utilize Solar energy.
