Why Choose a Condensing Tankless Water Heater
Condensing tankless water heaters (also called on demand water heaters) heat water only when you open a tap. High-efficiency condensing technology extracts extra heat from exhaust, improving efficiency and lowering fuel use.Comfort & Performance
- Continuous hot water for showers, laundry, and dishes.
- Smart recirculation options to reduce wait times at distant taps.
- Right-sized output with high turndown ratios for stable temperatures.
Efficiency & Savings
- Reduced standby losses vs. tanks that constantly re-heat.
- Condensing design captures more heat from exhaust.
- Eligible for future utility incentives when available (varies by program).
Reliability & Warranty
- Stainless-steel heat exchangers on premium models.
- Longer parts/heat-exchanger warranties vs. standard tanks.
- Compact, wall-hung design with serviceable components.
