How to Choose a Water Heater Installer in Lexington
Match the Unit to Your Space
A heat pump water heater needs warm air and clearance around it; tankless units need adequate gas line and venting. Ask the installer to confirm your space suits the unit before you buy.
Compare Efficiency (UEF)
Ask for the Uniform Energy Factor (UEF) of each option. Higher UEF means lower operating cost — heat pump units lead, followed by condensing tankless.
Confirm Sizing
Right-size for your household: tank gallons or tankless flow rate (GPM). An undersized unit runs out of hot water; an oversized one wastes money.
