Tankless Water Heater Installation
What Are Tankless Water Heaters and Why They Matter
Tankless water heaters (also known as on-demand or instantaneous water heaters) provide hot water only when you need it. Unlike traditional tank systems that store and continually heat water, tankless units heat water as it flows through the system, offering unlimited hot water with greater energy efficiency.
Tankless water heaters matter because they reduce energy waste, provide continuous hot water, and take up less space. They’re ideal for homeowners looking for improved efficiency, longer lifespan, and better performance. Professional installation and service are essential since these systems require proper sizing, safe gas or electrical connections, and regular maintenance to prevent mineral buildup. Homeowners often need tankless water heater service when upgrading from a tank unit, experiencing inconsistent hot water, or facing system error codes.
