Technology in the home is very important to our well being. Heating systems are what provides the comfort within the shell we call a house. Without systems to send the heat throughout the building we would have a tendency to stay near the source of heat. One can think back to the cave man days when the fire was the only focal point within their community. We also use systems to provide further home comforts such as refrigeration and air conditioning. Heating systems help cook our food such as the stove, microwave oven and the toaster.
