Experiencing a lack of hot water in specific areas of your home can be frustrating. When the issue is confined to places like the kitchen while the bathroom continues to receive hot water various localized factors may be at play. This troubleshooting guide explores potential reasons and solutions for hot water absence in specific areas.

1. Faulty Faucet or Fixture

Description: The issue may be specific to a particular faucet or fixture.

Solution: Inspect and if necessary replace the malfunctioning components in the kitchen faucet. Consider seeking professional plumbing assistance if needed.

2. Clogged Pipes
