capacity.<\/span><\/span><\/span><\/p>\n<p><span class=\"HwtZe\" lang=\"en\"><span class=\"jCAhz ChMk0b\"><span class=\"ryNqvb\">It is this decarbonization that is currently a challenge for the Polish heating sector.<\/span><\/span> <span class=\"jCAhz ChMk0b\"><span class=\"ryNqvb\">For the most part, it concerns larger heating systems with ordered capacities above 20MWt, for which it is necessary to meet the requirements of an Effective Heating System.<\/span><\/span><\/span><\/p>\n<h3><strong><span class=\"HwtZe\" lang=\"en\"><span class=\"jCAhz ChMk0b\"><span class=\"ryNqvb\">Effective

ChMk0b\"><span class=\"ryNqvb\">By December 31, 2027, the energy-efficient heating system is to use 50 percent.<\/span><\/span> <span class=\"jCAhz ChMk0b\"><span class=\"ryNqvb\">renewable energy or

class=\"HwtZe\" lang=\"en\"><span class=\"jCAhz ChMk0b\"><span class=\"ryNqvb\">The perfect CHP unit for this scale of investment is a gas turbine, which is explained in more detail later in this
