If you’re here to learn about heat traps on a water heater, you’ve come to the right spot. This article will briefly review the component, how it works, the installation guide, and its importance.
After reading this article, you should be able to address any heat issues with your water heater. If you’re ready, let’s begin our discussion.
Heat Trap on a Water Heater
Keeping your house economical requires being energy efficient.
Significant energy savings are possible when heat traps are installed on the water heater tank. The US Department of Energy claims you can save between $25 and $60 yearly on water heating expenses.
The device is placed in modern water heaters to increase energy efficiency and stop heat loss. You can add it, though, if your water heater is an older model or needs one.
For a heat trap to function, hot water must not return to the cold line. This will lessen heat loss while preserving the heater’s internal water temperature.
Understanding a Heat Trap and its Function
Another name for heat traps is heat trap nipples. These are pipe loops or valves on the hot water exit and cold water inlet of more recent water heater models.
Balls inside the apparatus either float or sink into a seat to impede convection. The valves are packaged in pairs and have separate designs for use in the hot and cold water lines.
The device can, for example, let water enter a water heater tank while stopping unneeded hot water from escaping. In this case, it will keep the cold water cold and the hot water hot in the tank.
The ball, or flap, returns to its starting position when the faucet is turned off.
Although there are many different designs for heat traps, they all have the same function. They are made to be both ecologically friendly and to reduce energy costs.
Heat traps can also help extend the water heater’s lifespan by lessening the strain on the electric heating elements.
Water Heater Heat Trap Installation Guide
Installing a heat trap is an intricate process. It’s best to leave the installation to the pros.
However, you can continue the process if you believe in your abilities. This section will walk you through the steps to fix this component.
The first step is to apply pipe thread compound to the ends of each heat trap thread. Water heaters often use two heat traps, each with two sets of threads and a colored check valve.
After coating both ends, spin the heat trap’s threads with the blue check valve into the water heater’s inlet port. Then, use your hand to tighten the heat trap.
The heat trap’s threads with the white or red check valve are twisted into the heater’s outlet port. Using a pipe wrench, tighten each heat trap one more time.
Once done, use the blue valve to connect the heat trap to the building’s cold water supply pipes. Use an adjustable wrench to properly tighten the water pipe fitting.
When you’re finished, screw the heat trap into the water heater’s port and attach the hot water supply pipe fitting. Also, tighten the water pipe fitting with an adjustable wrench.
Important note: Never use a torch to impart heat to a water heater when installing a heat trap. This is a result of the check valve melting or deforming.
Valves to Check When Installing a Hot Water Heater
In addition to heat traps, you should consider other things when maintaining your water heater.
These include soak pits, temperature or pressure relief valves, expansion control valves, tempering valves, and gas shut-off valves.
Let’s take a closer look at each of these parts to ensure we understand.
-
Expansion Control Valves
Expansion control valves are fitted into water heaters.
A pressurized and unvented water heater system restricts the maximum pressure by releasing the drain line’s surplus pressure.
When installing your water heater, the valve should only be fitted on the cold or intake installation. This is because its primary function is to handle the extra pressure produced during a typical heating cycle.
-
Tempering Valves
Tempering valves are another aspect to consider when installing your heating system. They ensure that the temperature of your hot water is safe for use in personal hygiene.
Additionally, the temperature-sensitive element in the valve modifies the amount of cold water based on the hot water system’s water temperature. It also lowers the temperature of your hot water at the faucet.
-
Gas Shut Off Valves
Another fantastic part of a water heater is a gas shut-off valve.
It is intended to enable manual gas flow isolation in LPG and natural gas systems. In a similar vein, this component needs to be considered when installing a new water heater.
-
Soak Pits
Another essential part of a hot water heating system is a soak pit. Its purpose is to regulate hot water or discharge steam.
The gadget doesn’t harm humans, annoy, or damage structures. Two pits are essential for specific water heaters. The base of the unit is covered in gravel.
-
Temperature/Pressure Relief Valves
Ensure the safety of temperature or pressure relief valves installed on water heaters.
This gadget ensures an unvented, pressured water heater never gets hotter than 99 °C. They provide the standard thermostatic controls malfunction.
In addition, the valves can protect against overpressure and overtemperature risks in any area where unvented containers are used to hold water.
- Gas pressure tests
Anyone installing a gas-powered water heater should test the unit after installation to ensure the gas tightness of the system and the piping.
The hot water system should also be serviced every two years after installation to ensure it continues to operate smoothly.
Heat traps are a small but crucial part of modern water heaters. They help prolong the water heater’s longevity, decrease heat loss, and improve energy efficiency.
