Heat is energy and when we produce heat we need to use energy in its production. There are natural methods for producing heat without burning or using fuels but these methods are not practical or available to the general populace for residential, commercial, and industrial use. The production heat, whether for residential, commercial, or industrial uses, uses energy and energy costs money. It is thereby necessary to have reliable and proven methods of measuring the amount of heat produced using a specific quantity of energy. Employing these reliable and proven methods we can also use the data to determine the best methods of producing heat for homes, businesses, and industry.
