Should I Remove Water Heater Heat Traps

Heat traps on water heaters are incredibly useful. They help reduce heat loss and make the tank more energy-efficient. The tiny devices are installed on the cold-water inlet and hot-water outlet pipes. This prevents hot water from flowing back when there’s no demand. How do they work? Thermosiphon action. Cold water sinks and warm water rises. The heat trap nipples inside each pipe let water flow one-way. So, heated water stays put.

Key Takeaways

  • Water heater heat traps are small devices installed in the hot and cold water pipes connected to the water heater.
  • The purpose of heat traps is to prevent heat loss from the water heater, thereby increasing its energy efficiency.
  • Heat traps work by allowing water to flow in one direction only, preventing the escape of hot water and the entry of cold water.
  • Removing heat traps can result in increased heat loss from the water heater, leading to higher energy consumption and utility bills.
  • However, there are certain situations where removing heat traps may be necessary, such as when they become clogged or malfunction.
  • It is recommended to consult a professional plumber before removing heat traps to ensure it is done correctly and does not cause any issues with the water heater system.
  • Regular maintenance and cleaning of heat traps can help ensure their proper functioning and prevent the need for removal.

Removing heat traps can be bad news – increased energy consumption and higher bills. Without these devices, hot and cold waters mix freely, and the heater has to work hard to keep the temperature constant.

Heat traps first appeared in the 2000s. AO Smith designed flexible hoses with trap nipples to boost performance.

In conclusion, heat traps on water heaters can be a life-saver! Unless you’re a vampire, of course…

What are water heater heat traps?

Do you like having lukewarm showers? Then get water heater heat traps! These devices are installed in pipes to stop heat loss and increase energy efficiency. They use a rubber flapper or two separate nipples to let hot water flow in one direction while preventing cold from entering the tank.

By doing this, it maintains a constant temperature and reduces the need to reheat water. Plus, they save energy and money on electricity. Installing them is easy – just attach them to the cold water inlet and hot water outlet pipes. For extra protection, use dielectric nipples or flex lines. If unsure, consult a professional plumber.

Larry had problems with his hot water supply and energy costs. He had an old water heater without heat traps. So, we installed them!

Heat traps are designed to retain heat in the tank and stop cold water from returning. This helps reduce energy losses. They are placed on the cold water inlet and hot water outlet pipes of a tank-style water heater. A ball or flapper-style valve lets water flow one way. That promotes hot water rising and cold water sinking.

Installing heat traps is easy. Turn off the electricity or gas supply to the water heater. Shut off the cold-water supply valve. Unscrew both nipples at the top of the tank. Put plumber’s tape or pipe joint compound on the new heat trap nipples. Screw them in place. Restore the electricity or gas supply. Turn on the cold-water supply valve.

The result? Larry saw a big improvement in his hot water and in his monthly bills. Heat traps helped keep more heated water in the tank. That means less standby mode operation and energy use.

If you want to save on energy costs, consider installing heat traps. It’s simple and cost-effective. You’ll get more hot water and lower electricity bills.
