G215/4 Complete Boiler 4 Section

The G215/4 Complete Boiler (4‑section) is a factory‑assembled Buderus G215 series boiler assembly designed for hydronic heating installations, offering a modular four‑section configuration for straightforward field integration and service. The G215 family features a three‑pass heat flow, tongue‑and‑groove gas‑tight section construction and a 3" thermal jacket to limit standby losses; the series is listed at 86% AFUE. I could not locate part number 7738000112 on Bosch North America sites, so this description is based on G215 series documentation. (bosch-homecomfort.com)
