Or, you can have a system with one unit inside the building and one outside.<\/p>\n<h5>Water source heat pumps<\/h5>\n<p>Water source heat pumps use the energy stored in ground water, surface, or sea or sewage water. The heat pump takes heat from the water and makes it available for heating, cooling and preparation of hot water. Water source heat pumps are particularly efficient because water is a very good energy carrier.<\/p>\n<h5>Ground source heat pumps<\/h5>\n<p>Ground source heat pumps use the energy stored in the ground. They extract heat from the ground either by a vertical or horizontal collector.<\/p>\n<h5>Electrically and thermally driven heat pumps<\/h5>\n<p>Many heat pumps use electricity to drive the compression cycle \u2013 meaning to heat up the energy from the air, water or underground a bit more. The heat pump can be plugged in and use renewable electricity.<\/p>\n<p>Thermally driven heat pumps use heat or an engine to drive the compression cycle instead.<br \/>There are three main types of thermally driven heat pumps. Gas sorption heat pump (GAHP) and thermal compression heat pump (TCHP) are both covered by the standard EN 12309 and gas engine heat pump (GEHP) is covered by the standard EN 16905.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-b18c6dd e-flex e-con-boxed e-con e-parent\" data-id=\"b18c6dd\" data-element_type=\"container\" data-e-type=\"container\" data-settings=\"{&quot;jet_parallax_layout_list&quot;:[]}\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-baf0fe7 elementor-widget elementor-widget-heading\" data-id=\"baf0fe7\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Where can heat pumps be used?<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-66799ad e-con-full e-flex e-con e-child\" data-id=\"66799ad\" data-element_type=\"container\" data-e-type=\"container\" data-settings=\"{&quot;jet_parallax_layout_list&quot;:[]}\">\n\t\t<div class=\"elementor-element elementor-element-758e6b5 e-con-full e-flex e-con e-child\" data-id=\"758e6b5\" data-element_type=\"container\" data-e-type=\"container\" data-settings=\"{&quot;jet_parallax_layout_list&quot;:[]}\">\n\t\t\t\t<div class=\"elementor-element elementor-element-e6d683e elementor-widget elementor-widget-image\" data-id=\"e6d683e\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"610\" height=\"300\" src=\"https:\/\/ehpa.org\/wp-content\/uploads\/2025\/08\/pumps_used_image_1.webp\" class=\"attachment-large size-large wp-image-21606\" alt=\"\" srcset=\"https:\/\/ehpa.org\/wp-content\/uploads\/2025\/08\/pumps_used_image_1.webp 610w, https:\/\/ehpa.org\/wp-content\/uploads\/2025\/08\/pumps_used_image_1-300x148.webp 300w, https:\/\/ehpa.org\/wp-content\/uploads\/2025\/08\/pumps_used_image_1-600x295.webp 600w\" sizes=\"auto, (max-width: 610px) 100vw, 610px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-bc83a98 e-con-full e-flex e-con e-child\" data-id=\"bc83a98\" data-element_type=\"container\" data-e-type=\"container\" data-settings=\"{&quot;jet_parallax_layout_list&quot;:[]}\">\n\t\t\t\t<div class=\"elementor-element elementor-element-0f592a5 elementor-widget elementor-widget-text-editor\" data-id=\"0f592a5\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>Heat pumps can provide CO2-free heating and cooling and hot water in all types of home, and for commercial spaces like hospitals and offices.<\/p>\n<p>Heat pumps can also provide heat for industry. European industries like steel, chemicals, paper, food, and tobacco use a huge amount of energy \u2013 about a quarter of the EU\u2019s consumption.<\/p>\n<p>District heating allows heat to be produced in one place and then distributed via insulated pipes to houses and businesses.<\/p>\n<p>The heating and cooling sector is responsible for 51% of the final energy demand in Europe and for 27% of its CO2 emissions.
