Step-by-step explanation:
Energy is the key component in heating systems. Heating systems use energy, typically in the form of electricity or fuel, to generate heat. The heat is then transferred to the surrounding environment, typically through the use of a heat exchanger, in order to raise the temperature and provide warmth. The efficiency of a heating system depends on the amount of energy input compared to the amount of heat generated and distributed. To reduce energy consumption and costs, it's important to use energy-efficient heating systems and to properly maintain and operate them.
