Home improvement experts recommend performing preventative maintenance annually on tank-style water heaters, which a professional technician can help you with. The position of the heat-out pipe at the top of the tank does the rest. The secret to a water heater's design for separating cold, incoming water from hot, outgoing water is that it relies on the principle that heat rises to do the hard part. Water exiting the water heater at the top is always the hottest in the tank at any given moment because it's the nature of hot water to rise above denser, cold water. The heat-out pipe is located near the top of the tank. The heating mechanism - either a burner or an element - stays on until the water reaches temperature.Īs the water heats, it rises to the top of the tank. The dip tube feeds cold water from your home's water lines to the bottom of the tank's interior, where the water starts to warm up. Usually, the thermostat is located underneath a protective cover plate and has a knob or dial you can turn to set the temperature. Setting your water heater to a lower temperature saves energy, too, and if you remember to dial back the heat when you go on vacation, you'll experience even more energy savings. Now, let's see how all these parts work together to provide you with hot water. Sacrificial anode rod: Made of magnesium or aluminum with a steel core, the sacrificial anode rod is suspended in the water heater tank to help retard corrosion.Pressure relief valve: This safety device keeps the pressure inside the water heater within safe limits.Drain valve: Located near the bottom of the exterior housing, the drain valve makes it easy to empty the tank to replace the elements, remove sediment or move the tank to another location.Gas water heaters use a burner and chimney system instead. Heating mechanism: Electric water heaters have heating elements inside the tank to heat the water.Some electric water heaters have a separate thermostat for each element. Thermostat: This is a thermometer- and temperature-control device.Heat-out pipe: Suspended toward the top of the tank's interior, the heat-out pipe allows the hot water to exit the water heater.It's a separate component from the heater located outside and above the unit. Shut-off valve: The shut-off valve stops water from flowing into the water heater.Dip tube: Water enters the water heater through the dip tube at the top of the tank and travels to the tank bottom where it's then heated.Over that, there's a decorative outer shell and possibly an additional insulating blanket. The exterior of the tank is covered in an insulating material like polyurethane foam. Tank: The inner shell of a water heater is a heavy metal tank containing a water protective liner that holds 40 to 60 gallons (151 to 227 liters) of hot water at around 50 to 100 pounds per square inch (PSI), within the pressure range of a typical residential water system.The slim profile of this unit, less than 10" high, allows for installation in tighter ceiling spaces than other ducted units. Item may differ in appearance from photo above. All Technical specs are subject to change. The Ceiling Concealed Ducted is offered in an array of sizes to easily accommodate each rooms unique heating and cooling size requirement when utilized in a multi-zone system: CDMQ24WVJU9 (7,000) BTUs), FDMQ09WVJU9 (9,000 BTUs), FDMQ12WVJU9 (12,000 BTUs), FDMQ15WVJU9 (15,000 BTUs), FDMQ18WVJU9 (18,000 BTUs), FDMQ24WVJU9 (24,000 BTUs). These ratings will change based on use in a multi-zone application and whether that installation is using ducted only or mixed ducted and non-ducted indoor units. It features ratings of 17.8 SEER, 11.1 EER and 10.3 HSPF. When paired with the inverter, variable speed compressor in a single zone application, this system will deliver the capacity required and reduce energy consumption. Daikin’s ducted unit is easily concealed in a ceiling in a non-distracting way. The major advantage to the FDMQ Medium Static unit is the ability for longer duct runs giving the consumer numerous installation opportunities and the ease of implementing high MERV filters. The ducted ceiling system is designed to quietly blend into the ambiance of shops, restaurants, small offices or home environments. A wired Controller must be purchased separately to operate this unit. At this time, there is no hand held remote available for this unit. A controller is not included and must be purchased separately. This is changeable in 13 stages by the controller BRC1E73. The new FDMQ line of concealed ducted ceiling units are a medium static unit providing external pressures up to 0.6" w.c.
