Water Heater Heat Traps

Heat traps are valves or loops of pipe installed on the cold water inlet and hot water outlet pipes on water heaters.

Water heater heat traps. This increases the efficiency of your hot water tank. Heat traps are made to completely isolate the heat inside of a water heater so that it stays inside of the tank. Heat traps heat traps are elements installed on the electric and gas powered water heaters and are used to prevent heat loss from inside the storage tank when the flow stops while increasing the overall efficiency. The ball type heat trap has a ball inside the part which is floating under the pressure when water is in use hot site while when cold water is entering the tank water flow pushes the ball down from the seat of the nipple.

The two pipes that connect to a water heater both the cold inlet pipe and the hot. Npt x 3 4 in. Hot water will rise and cold water will sink. Traditional heat trap loops sometimes referred to as goosenecks take advantage of thermal convection.

Rheem protech dielectric heat traps preventing heat loss through the inlet and outlet pipes of a water heater while the heater is idle by using a flapper valve. They re available as nipples with either a flap or ball or you can bend the pipes to form a gooseneck heat traps will prevent any heat from escaping while in standby mode. The fittings are 3 4 in. Water heater heat traps are almost essential to install.

The little black rubber flappers in the heat traps are an improvement over previous heat trap nipple designs they are what they started using after all the problems with earlier designs that used a ball to trap the hot water. By adding a u shaped dip in the pipeline the hot water gets stuck at the top of the loop while the cold is able to pass through the dip and enter the tank.
