Ultra-Reliable Conventional Boilers From Bosch

Non-condensing boilers from Bosch deliver reliable heating and hot water with high efficiency and low operating costs. When the gas valve is released, the gas flows into a combustion chamber, where the gasses are burned and converted into heat and byproducts. Then, the heat is transferred to cold water in the boiler's pipes via the heat exchanger to provide home heating. The byproducts are released into the flue to safely release the fumes outside. Bosch non-condensing boilers offer dependable heating as well as easy maintenance.

GC144 Buderus Boiler

Buderus GC 144 Non-Condensing Boiler

Industry-leading hydronic heating technology.

Superior Design

The GC144 Series boiler requires very little space-but don't let it's size fool you. The slim profile and convenient side piping are designed for quick and easy installation-especially as a replacement boiler.

Quality Build

Buderus patented GL-180M silicone-injected cast iron has an excellent corrosion resistance, 40% greater flexibility and high thermal conductivity to resist thermal shock under conditions of rapid temperature change. Special compounds tightly join cast iron sections and provide a gas-tight seal for safe and effective operation.

Efficiency Optimized

These Buderus boilers are available for use with natural gas or can be easily converted to propane. Factory-tested stainless steel premixed burners allow for low emissions and superior thermal insulation virtually eliminates standby temperature losses.

  • 3 models with inputs from 74,000 to 132,500 BTU/Hr
  • 85% AFUE efficiency
  • Compact boiler with advanced low temperature technology
  • Side-piping design for convenient boiler retrofit installation

G215 Buderus Boiler

Buderus G215 Non-Condensing Boiler

Quality Construction

Buderus boiler sections are assembled with beveled, surface profiled push nipples for watertight operation. Flueways of Buderus boilers are sealed gas-tight with tongue and groove section design and elastic high temperature resistant sealing rope. A permanent dry door gasket ensures repeated positive sealing off of the full swing burner door.

Three-Pass System

Buderus developed a full three-pass system to help increase efficiency. The unique way heat flows through the G215 boilers allows the water to be heated three separate times. The full 3" thick thermal insulation helps to maintain a higher water temperature even after the boiler has gone into standby mode.

  • 5 models with outputs from 134 MBH to 294 MBH
  • Improved Efficiency (86% AFUE)
  • Rear tappings and flue connection to streamline appearance
