Tankless Water Heaters

Tankless water heaters provide hot water on demand—heating only when needed. They’re a strong option for space-saving installs and efficient operation, especially when sized correctly for flow rate (GPM) and temperature rise based on local incoming water temperature.

The most common performance issue is undersizing. If peak usage requires multiple fixtures at once, a unit must be selected to support the combined demand. Also verify fuel type (electric or gas), venting (for gas), and water quality considerations to reduce scale buildup.

• Compare GPM flow rate at your required temperature rise
• Confirm fuel type and installation requirements (venting/electrical)
• Plan scale protection and maintenance access
• Verify clearances, condensate (if applicable), and local code requirements

For best results, match the unit to real peak usage (showers, sinks, appliances) and local water conditions. Proper sizing + maintenance = reliable performance and fewer callbacks.

Pro tip: If your area has hard water, plan for flush service or scale control. Scale is the #1 reason tankless performance drops over time.
