In this article, we will show you how to identify if your hot water heater is bad and the pros and cons of repairing or replacing it.
What is a Hot Water Heater?
A hot water heater is a household appliance that uses energy to heat and store water for daily use. There are two main types of hot water heaters: storage tank and tankless. Storage tank water heaters can hold 20-80 gallons of hot water, while tankless heaters heat water on demand.
Why is a Hot Water Heater Important?
A hot water heater is essential for many household tasks, such as washing dishes, doing laundry, and taking showers. Without hot water, daily life becomes much more difficult.
How Long Does a Hot Water Heater Last?
The lifespan of a hot water heater depends on maintenance, usage, and the type of unit. On average, a storage tank water heater can last 8-12 years, while tankless heaters can last up to 20 years.
Signs Your Hot Water Heater is Failing
There are several signs that indicate your hot water heater may be failing and needs to be replaced.
1. Age
If your hot water heater is over 10 years old, it may be time to replace it. As hot water heaters age, they become less efficient and more prone to failure.
2. Rusty Water
If you notice rusty water coming from your hot water faucet, it may be a sign that your hot water heater is rusting on the inside and needs to be replaced.
3. Strange Noises
If your hot water heater is making rumbling, popping, or banging noises, it may be a sign of sediment buildup. This can cause the unit to overheat and eventually fail.
4. Leaks
Leaks around your hot water heater are a clear sign that something is wrong. It could be due to a faulty valve or a crack in the tank.
5. Inconsistent Water Temperature
If your hot water is not consistent, it could be a sign of a failing hot water heater. This can be caused by a variety of issues, including a malfunctioning thermostat or a buildup of sediment.
6. High Energy Bills
If you notice a significant increase in your energy bills, it could be due to a failing hot water heater that is working harder than it should be.
7. Complete Loss of Hot Water
If you don’t have any hot water at all, it’s evident that your hot water heater needs to be repaired or replaced.
