If you have an instantaneous electric hot water heater, you’ll want to make sure it’s protected from power surges – and that can be tricky. It’s not a particularly exciting job, but it is important! Here are some of your options for protecting your heater from power surges.
The first option is to install a surge protector. This is a good choice if you have the budget because it offers the most reliable protection. You can buy a surge protector at most hardware stores. Just make sure you get one that’s compatible with your hot water heater, and that it has enough outlets for all of your appliances.
The second option is to install an isolation switch. An isolation switch is designed to disconnect the electricity supply when there’s a power surge. It will also protect your other appliances from the surge as well, so if you have multiple items plugged into the same power board, this could be a good option for you.
The third option is to install an RCD (Residual Current Device). An RCD will detect any imbalances in the electricity supply and immediately cut off the power – protecting your hot water heater (and any other connected appliances) from damage or destruction in the process.
Finally, you could also consider installing a lightning arrester. This device will absorb any excess voltage when there’s a lightning strike or other sudden increase in voltage, protecting the appliance and any other connected items from damage or destruction.
Whichever option you choose, make sure it’s installed properly by someone who knows what they’re doing – otherwise it won’t provide any protection at all! And if you ever suspect there might be an issue with your hot water heater, don’t hesitate to call in an electrician or plumber right away – better safe than sorry!
