Why Is My Water Heater Making A Hissing Noise?

If your water heater is hissing immediately after use, it could be your heater’s safety mechanism working. The 707 Compact Instant Water Heater, for example, has an in-built pressure release device that allows for the safe venting of excess pressure and hot water. However, this does not mean that you can ignore the hissing. It could be that the water level is set too high, or that the internal thermostat has failed. To properly identify and fix the issue, it is advisable to seek professional help.

Faulty Relief Valve

The temperature and pressure relief (TPR) valve that manages the safe venting of hot water and pressure may be faulty. This can cause the faulty valve to hiss, even when at normal pressure and temperature. Finding out the reasons why your water heater is corroding helps immensely in preventing the TPR valve from failing. If you spot a ring of rust around the valve, it is time to take corrective action and prepare for a water heater replacement.

Condensation

When using a storage water heater for some time, the water level in the tank drops, prompting a fresh injection of cold water. This results in moisture condensing on the outside of the tank. The flash evaporation of the condensation that rolls down to the hot surface produces a hissing sound.

Water Heater Leaking

If your water heater is constantly hissing, it could be a sign of a faulty water heater. A small leak may have sprung on your water heater. There are many reasons behind a leaking water heater. Following the tips to identify water heater leaks and fix it is a great way to prevent your water heater from hissing. If you are having trouble fixing it on your own, you can seek professional water heating leaking services.
