Tank water heaters are the most common type, typically holding 20 to 80 gallons of water. These systems work by continuously heating water, which can run out, especially in larger households. They usually have a set temperature defined by the thermostat.
Tankless Water Heaters
Tankless water heaters, or on-demand heaters, heat water only as needed. While they’re more energy-efficient, they can struggle to provide hot water simultaneously to multiple fixtures, leading to temporary gaps in hot water supply.
Hybrid Water Heaters
Hybrid systems combine both tank and tankless features, providing a reserve of hot water while also heating on demand. Their complexity can sometimes lead to unique issues requiring a specialized approach.
Troubleshooting Hot Water Problems
If you’re confronted with the challenge of a hot water failure, follow this basic troubleshooting guide:
Step 1: Check the Power Supply
If you have an electric water heater, ensure that it is receiving power. Check the circuit breaker to see if it has tripped. If you have a gas heater, ensure that the gas supply valve is open.
Step 2: Inspect the Thermostat
Locate the thermostat on your water heater. Most water heaters will have at least two thermostats; one for the upper heating element and one for the lower. Ensure they are set to appropriate temperatures (generally between 120°F – 140°F is ideal).
Step 3: Flush the Tank
If you suspect sediment buildup, it’s time to flush the tank. This process involves draining the tank and flushing it with fresh water to remove accumulated minerals.
How to Flush a Tank Water Heater:
- Turn off the power/gas.
- Connect a garden hose to the drain valve at the bottom of the tank.
- Open the valve and drain the tank into a bucket or drain.
- Once empty, close the valve, remove the hose, and refill the tank.
Step 4: Inspect for Leaks
Look around your water heater and associated piping for any signs of leaks. These can lead to pressure loss and inadequate hot water supply.
Step 5: Consult the Manual
If all else fails, it often helps to consult the user manual for your water heater. It may have specific troubleshooting steps tailored to your model.
When to Call a Plumber
Sometimes, the issue at hand can be more severe than what a homeowner can address. It is wise to call in a professional plumber if:
