Because the system transfers heat instead of producing it directly, COP values often exceed 3 under moderate conditions \u2014 meaning three units of heat delivered for every unit of electrical energy consumed. What this means is that it would 3 times as much electricity to deliver the same amount of energy if using resistance heating.<\/p>\n\n\n\n\n\n<h4 class=\"wp-block-heading\">A Simple Analogy<\/h4>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-43a823aba84a3f564030ea07ee05613a\">Think of a refrigerator: it pulls heat out of food and releases it into the room.
