27 - Water Heater Water heaters are sealed systems which contain a great deal of pressure. There should be a drain pipe attached to this valve which terminates at a safe location away from body contact. Water heaters sometimes make gurgling noises which are typically the result of built up calcium inside the tank. Our description of the heating system includes where the unit is located and the fuel used to generate the heat. Forced air furnaces and water boilers can operate on gas, oil or electricity.
Heat pumps utilize electricity to drive the motors and compressors.
Furnace size is listed for reference only, if available, and no calculations are performed during this inspection to determine the adequacy or efficiency of the heating system. 29 - Condition Systems are tested using normal homeowner operating controls. If pilots or circuit breakers are off at the time of the inspection, the inspector will not ignite or activate the system. You can contact the utility provider for evaluation of the heating system. 30 - Venting Fuel burning appliances exhaust the products of combustion to the exterior through vent pipes.
