How Will I Know When To Replace My Water Heater?

Hot water is a necessity we take for granted… unless there’s a problem. To keep that hot water supply flowing, it’s important to know when to replace your water heater.

How Long Does A Water Heater Last?

Traditional tank water heaters experience a great deal of wear and tear. The reason is that they don’t just warm up your water; they also have to keep it hot until you’re ready to bathe or wash dishes. As a result, you can expect a tank water heater to last 8-12 years, on average.

The newer tankless water heaters produce hot water on demand, starting the heating process as soon as you turn on a faucet. Because they only heat water, without storing it, these heaters experience less stress and strain. Expect a tankless heater to last up to 20 years.

These Signs Will Tell You When To Replace Your Water Heater

1. The Water Heater Is Aging

Your water heater has worked hard for a long time, but if it is approaching the end of its service life (8-12 years for a tank heater or 20 years for tankless, as previously mentioned), prepare to say goodbye. Are you not sure how old your water heater actually is? Check the manufacturer’s label. It will give either the installation date or a serial number which indicates the heater’s age.

2. Your Hot Water Is Discoloured

Discoloured tap water can occur for many reasons, but when only the flow from the hot water tap is an odd colour (usually a reddish-brown shade), it’s most probably caused by rust buildup inside the water heater tank. A rusty tank means that you will need to replace your hot water heater.

3. You Find Water Leaks On The Heater Or The Floor

Inspect your water heater — and the floor underneath — for leakage on a regular basis. Sometimes a leak can be repaired, if it’s from either the drainage valve or the temperature and pressure relief valve. When the tank itself is leaking, though, it’s time to replace your water heater, before the tank gives way and causes severe water damage to your house and possessions.

4. There’s Not Enough Hot Water

When your shower is often (or always!) not quite warm enough, there are a number of possible explanations. Your water heater’s thermostat or dip tube may not be damaged or malfunctioning; replacement of these parts is fast and inexpensive.

Alternatively, mineral deposits on the water tank’s floor could be keeping the burner from working right. Professional flushing will remove this sediment and get your water heater back up to speed again.

Another possibility is that your household has simply outgrown your current unit. As you expand your family or add appliances, for instance, your need for hot water tends to increase.

Now might be the perfect time to replace your water heater and upgrade to a newer, more energy-efficient model such as a John Wood Atmospheric or Power Vent water heater. Or you could be ready to make the change to a tankless variety, like the Navien Tankless water heaters.
