WHY FAMILIES CHOOSE TANKLESS WATER HEATERS
You could replace your 40-gallon tank with another 40-gallon tank. Or you could solve hot water issues once and for all. Tankless means:
- •Hot water that never runs out—properly sized for your home's demand
- •Lower monthly utility bills that add up over 20+ years
- •Reclaim valuable floor space in your utility room
- •One professional installation, decades of service
THE NASHVILLE HARD WATER REALITY
Nashville's moderately hard water (~100.5 mg/L, 4–7.6 grains per gallon) makes annual descaling essential for tankless longevity:
- •Annual professional descaling costs $150–$250 and restores like-new performance
- •Whole-home water softening protects tankless plus all fixtures and appliances
- •Most manufacturers require annual maintenance for warranty validity
- •Franklin and Brentwood have similar hardness requiring the same care
