Geothermal heat pump

high-temperaturelow-temperature

Proven high and low temperature heat pumps for up to 150°C and 70 MWth Heat pumps are an efficient and cost-effective solution for the generation of heat and cold. They lift the temperature by absorbing thermal energy from an existing low-temperature heat source and releasing it to a warmer space. The use of a heat source (e.g., waste heat from industries or renewable heat from nature, like rivers or geothermal sources) enables heat pumps to generate much more heat with a certain amount of electricity, than a simple direct conversion of electric power to heat could do. During the next years, heat generation will be electrified and decarbonized step by step, due to the gradual replacement of fossil-fired thermal power plants with renewable energies. Excess capacities of renewable energy can be converted into heat, paving the way to CO2-free heat generation. For modern district heating and cooling or industrial heating applications, Siemens Energy’s large-scale industrial heat pumps are the best and most efficient solution to convert electricity to heat. Heat pumps move thermal energy in the opposite direction of spontaneous heat transfer, by absorbing heat from a cold space and releasing it to a warmer one.
