Reliable Cast Iron Construction

A heavy‑duty cast‑iron heat exchanger and metal section connectors deliver long service life and consistent heat transfer—ideal for hydronic systems that run for decades.

Fuel‑Saving Integrated Control

The user‑friendly control includes an energy‑saving thermal purge that circulates residual warm water before firing the burner, helping reduce fuel use and chimney losses.

Right‑Sized For Typical Homes

With a Net IBR of about 45,000 BTU/h, the CG30 is a solid match for many smaller homes and well‑insulated spaces when properly sized to your radiation and heat loss.

Simple, Code‑Compliant Venting

This Category I natural‑draft boiler connects to a properly sized, lined chimney with a standard 4‑inch flue. That makes replacements straightforward in homes with existing chimneys.

Installer‑Friendly Layout

Clear front/side access, 1‑1/4" supply/return tappings, and included vent damper simplify piping and annual service. Many packages ship with a familiar Taco 007 circulator to speed up installs.
