A water heater is an essential part of any home, providing hot water for daily activities like bathing, cooking, and cleaning. When it starts malfunctioning, homeowners often face a common dilemma: should you repair or replace it?
Making the right decision depends on several factors, including the age of the unit, cost of repairs, and overall efficiency. This guide will help you understand when to repair or replace your water heater and how to make the best choice.
How Water Heaters Work
Water heaters use heating elements or gas burners to heat water stored in a tank or supplied on demand.
Types of Water Heaters:
- Tank water heaters
- Tankless water heaters

- Gas water heaters
Each type has its own advantages and maintenance requirements.
