Common Questions

Frequently Asked Questions

Annually. Littleton's hard water accelerates scale buildup inside the heat exchanger. Skipping maintenance shortens unit life and voids many manufacturer warranties.
In most cases yes, but it may require upgraded gas lines, new venting, or different electrical connections. We assess your setup honestly.
Generally yes β€” especially for larger households. They use 25–40% less energy for hot water, last 20+ years with proper maintenance, and never run out of hot water.
