U.S. Boiler Company PVG

The PVG is U.S. Boiler Company's side-wall-vented cast-iron gas water boiler, published on the official site as 'Gas, Water — Cast Iron Heat Exchanger' with an 85% Efficiency badge. The product page describes it as built on the same platform as the ES2 and designed as an optimal replacement boiler for homes without existing chimneys, venting directly through the side of the house; it lists natural or LP gas, high-quality boiler control components, a time-proven cast-iron design, a limited lifetime manufacturer's warranty, optional 5- or 10-year parts and limited labor warranty plans administered by CornerStone United, and the IHC Boiler Control System.

Boilers.ca documents the PVG at series level only. The official product page carries marketing copy and accessory links but no printed ratings table, no model list and no data sheet, so no model records are published; the page's 85% efficiency badge is recorded as the series figure with that limitation noted. Owners and service planners should work from the documentation for the unit's own series, and gas, venting or combustion work on any installed PVG belongs with a licensed contractor.
