With Tankless Coil

This item comes with a Beckett burner.

The V8H oil-fired boiler is designed for quiet operation while providing years of reliable and efficient service. As always, the jacket design and burner enclosure give the V8 a modern, finished appearance, and it is available in multiple heating capacities that can be configured for water or steam - with or without a tankless hot water heating coil. As one of the most versatile boilers available, the V8 is intended for installation in a wide variety of home styles and sizes. Beginning October 1, 2020, 03 through 07 section V8H water boilers will be upgraded to the DOE-2021 efficiency requirement of 86% AFUE.
