Heat traps are an important part of water heaters. They help make them use less energy. Heat traps stop the hot water in the tank from cooling down and being replaced with cold water.

You can install heat traps yourself, if you know a bit about plumbing. There are two main types. Ball style and gooseneck loop. The ball style is two balls that let hot water out and prevent cold water coming back in. Gooseneck loops help hot water move around.

Be careful when you install heat traps. They must be in the right spot. If there isn’t enough room or the pipe is too small, it can be tricky.

Using heat traps can save you up to 10% on electricity costs for heating water. They reduce the amount of energy used for standby heat loss. Heat traps are a great, cost-effective solution.

What is a heat trap and why do you need it?

A heat trap is a nifty component that boosts the energy efficiency of water heaters by blocking heat loss. It consists of valves or flaps that let hot water in, but not out. This keeps temperatures hot for longer, saving energy and electricity costs.

Heat traps prevent standby heat loss; when hot water sits in the tank, it cools down and needs to be reheated, wasting energy. Heat traps create a barrier between the hot and cold water sides of the tank, blocking convection currents that allow heat to escape.

Installing a heat trap is easy. Any homeowner with basic plumbing skills can do it. Just buy a heat trap nipple or kit from the hardware store. Turn off the power/gas; drain hot water to relieve pressure; disconnect cold/hot water pipes; apply joint compound/Teflon tape; connect nipples; reconnect cold/hot water pipes; and turn power/gas back on.

By installing a heat trap, you’ll get reduced energy bills, increased efficiency and endless warm showers! So don’t miss out, take action now and enjoy the long-lasting benefits of a more efficient water heater system.

Turn off the power or gas to your water heater. Then proceed with these steps:

  1. Drain water in the tank with a drain hose.
  2. Disconnect cold water inlet and hot water outlet pipes from the top.
  3. Attach heat trap nipples with Teflon tape or joint compound.
  4. Reconnect hot water outlet pipe to its port on top – securely tighten.
  5. Repeat process for cold water inlet pipe – all connections must be tight.

Heat traps reduce standby heat loss and potentially lower energy bills. Check local ordinances or consult a plumber for any requirements or guidelines. Fun Fact: Heat trap loops can save up to $40 annually on water heating costs according to the U.S. Department of Energy. So let’s install heat traps and keep that cold water from escaping.

Step-by-step guide on how to install a heat trap on your water heater

Installing a heat trap on your water heater is easy! It can help increase energy efficiency and lower heat loss. Heat traps stop hot and cold water from mixing, allowing for better hot water flow. Here’s a guide on how to install one.


Gather the materials you need. These may include heat trap nipples or kits, Teflon tape or joint compound, pipe fittings, and a flexible hose if needed.


Switch off the power supply. Electric water heaters need the circuit breaker turned off. Gas heaters need the gas supply turned off.


Decide where to put the heat trap. Usually near the top of the tank, on the hot water side. Use Teflon tape or joint compound. Connect one end of the heat trap to the hot water outlet using pipe fittings. Consider using a flexible hose for future maintenance.

Done! Now you’ve installed a heat trap. It uses natural convection to improve circulation. This reduces standby heat loss and lowers energy costs.

  1. Installing a heat trap is crucial for your water heater’s efficiency and longevity. It prevents heat loss, lowers energy costs, and improves hot water circulation.
  2. To do this, turn off the electricity or gas supply, close the cold water inlet valve, and attach the heat trap nipples to the hot water outlet and cold water inlet using Teflon tape or joint compound.
  3. Position the loops vertically, with one facing down (cold side) and one facing up (hot side).
  4. Then, turn on the cold water inlet valve and open a hot water tap. This creates a natural convection system, where hot water rises and cooler water flows back into the tank.

Regularly check for any corrosion or leaks around the heat trap joints or pipes. Flush your water heater annually to remove sediment buildup. Also, keep an eye on your electricity bills – if there’s a sudden increase, it could be due to issues with your heat trap system. I once had a noisy hot water tap and it was because the heat trap flap in the cold water side was stuck. Replacing the heat trap nipple and flap solved the issue.

Maintaining your water heater with a heat trap is a great way to boost efficiency and maximize its lifespan. Follow the installation process and do regular maintenance checks for the best results.
