A.O. Smith Models We Install
A.O. Smith organizes their residential lineup into two primary families: the ProLine series for reliable everyday performance, and the ProLine XE series for premium, high-efficiency applications. Below is an overview of the models Onze installs and services most frequently.
A.O. Smith ProLine Gas Water Heater
The ProLine gas line is a dependable choice for most Connecticut homes with natural gas service. Available in 40 and 50-gallon capacities, it handles standard residential hot water demands reliably. Atmospheric and power vent configurations are available to fit different installation setups. Backed by a 6-year tank warranty.
A.O. Smith ProLine Master Gas Water Heater
An upgrade over the standard ProLine, the ProLine Master is built with commercial-grade components for households with higher hot water demands.

A.O. Smith Voltex Hybrid Electric Heat Pump Water Heater
The Voltex is A.O. Smith’s flagship hybrid electric heat pump model.

Available in 50, 66, and 80-gallon capacities. ENERGY STAR certified and may qualify for federal tax credits and Connecticut utility rebates.
