They are typically available at a lower price point and can be a practical choice for budget-conscious buyers or those seeking a quick replacement.
Why choose a used water heater?
- Cost Savings: The most apparent advantage is the reduced purchase price.
- Availability: Used units are often readily available, especially in local markets.

Types of Used Water Heaters
Used water heaters come in various types, each suited for different needs and installation environments.
Tank Water Heaters
These are the most common type, storing a specific volume of hot water for immediate use. They are available in various sizes, from 30 gallons to over 80 gallons, making them suitable for homes of all sizes.
Tankless Water Heaters
Also known as on-demand water heaters, these units heat water only when needed. Used tankless units can be a good option for space-saving and energy efficiency, provided they are in good working condition.
Solar Water Heaters
While less common in the used market due to their specialized nature, some used solar water heating systems are available. They are environmentally friendly but may require more complex installation.
