Water is essential for healthy living both indoors and outdoors. Drinking water enters our homes, schools, and office buildings through one set of pipes and exits through a separate set of pipes. Heat is an idea that most of us take for granted. Heat can be produced by burning fossil fuels, such as natural gas, propane gas, or fuel oil. In newer buildings, heat pumps are used to produce heat.
Heat is essential for healthy indoor living.
It keeps your body warm indoors when it is cold outside. People can become very sick if exposed to extreme levels of cold climatic conditions. Therefore, heat is not only a comfort indoors, but a tool to protect the body. People need to be comfortable with the temperature and humidity of indoor air. When the weather is hot and humid outside, most people seek comfort inside from air conditioning units.
