MI-E-03-SPRK-WPC-N

Buderus GC144/32 Residential Gas Boiler W/ Electronic Ignition 85% AFUE 133K BTU Input
Superior Design The GC144 Series boiler requires very little spacebut dont let it's size fool you. The slim profile and convenient side piping are designed for quick and easy installationespecially 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.,
