How Do Tankless Water Heaters Work?
Tankless water heaters, also known as on-demand water heaters, provide instant hot water without the need for a storage tank. Unlike traditional water heaters that continuously heat water, tankless units heat water only when needed, making them more energy-efficient and cost-effective.
Key benefits of tankless water heaters include:
- Energy Efficiency: Uses less energy compared to conventional storage tank water heaters.
- Unlimited Hot Water: Provides continuous hot water supply as long as the demand stays within the unit’s capacity.
- Space-Saving Design: Compact and mounted on walls, freeing up valuable space in homes and businesses.
- Maximum Lifespan: Typically lasts up to 20 years, nearly double the lifespan of traditional water heaters.
However, even with these advantages, tankless water heaters require routine maintenance and prompt repairs to function efficiently. Hard water buildup, ignition failure, and sensor malfunctions are common issues that may require professional attention.
