Even though they’re made to last in an era where many things don’t have a long life span, your hot water heater won’t last forever. While it’s not unheard of for one of these units to last for years after the warranty has run out, there’s a real need to heed the call when your current unit starts showing signs of nearing the end of its days. Keep in mind that beyond the obvious inconvenience from losing the services of your hot water heater for even a short length of time, an unstable or malfunctioning unit could blow up and emit carbon monoxide gas or scald someone nearby. It’s in your best interests to look at a few warning signs that indicate your unit needs to be replaced. Dwindling efficiency is one of the first telltale signs that something needs to be done. Heating water generally makes up about 17 per cent of the energy use for your home. By keeping an eye on the monthly bills and looking for any spikes, you should be able to tell when the unit is getting too old to function properly. Other markers to pay attention to include having to wait for unusually long periods to get hot water, inconsistent temperatures and frequently running out of hot water. There are a few visual signs that you’ll want to look for as well. A pool of water under the base of the of the tank or other signs of leaking is a good indication that it is time for a replacement, while rust is generally a sign of corrosion and something that cannot and should not be ignored.
