Why Doesn't the Water Get Very Hot in a Home?

Numerous reasons can cause the lack of hot water in a home, regardless of the type of heater.

Lack of hot water in a house is never a pleasant experience. However, fixing this issue means it's essential to understand why it could occur in the first place. So let's discuss why the home's water won't get hot.

Gas leak

Gas leaks can cause issues with the hot water or lead to its complete absence.

Homeowners can inspect the connections and look for leaks to check for this issue. For starters, shut off the main valve, let the faucets drip, and feel the pipes for odor or wetness.

If homeowners see suspicious signs, they must contact professional contractors to inspect the issue further.

Leaky water tank

Water tanks need to be filled with water to work correctly. A lack of hot water can indicate a leak in the water tank.

Check the connections of the water tank, valves, and pipes to diagnose the issue. The tank likely needs replacement if there's water in any compartments.

Gas valve issue

Gas water heaters that don't supply hot water may have an issue with the gas inlet valve and supply tube.

First, check the gas valve to ensure there is no sign of leaks. The valve should be in the proper position and secured. Then, make sure to switch on the gas.

Electric water heater problem

Water heaters (both electric and gas) can cause a lack of hot water in a home. The electric heater most often runs on a separate circuit.

Homeowners can test the heater by switching power sources. If doing so doesn't help to heat the water, the electricity is not flowing to the water heater.

Find loose connections and reset the fuses. They may trip. If fuse tripping were the issue, hot water should return to the home within 30 minutes of resetting.

Thermostat issues

Thermostats must be set between 120 and 140 degrees Fahrenheit to produce hot water. If there is no hot water, homeowners should check their upper thermostat.

In case of thermostat damage, a replacement may be necessary. Inconsistent maintenance can also cause thermostat issues, so it's essential to clean and drain the water heater regularly.

Small heater tank

Water heater tanks that are too small run out of hot water quickly. Also, electric water heaters take longer to heat compared to gas heaters. Sometimes, homeowners may require a larger storage unit to fix the lack of hot water.

Contact professional plumbers for water heating issues

Numerous reasons can cause the lack of hot water in a home, regardless of the type of heater. Homeowners who experience frequent problems with hot water should inspect their plumbing system for leaks.

Additionally, consider scheduling an appointment with local plumbers to fix the issue quickly. This way, homeowners can maintain the system's energy efficiency.
