Galaxy GG Series Gas Boilers

The computer-aided design of Galaxy's heat exchanger maximizes the transfer of heat from the flame to the water in your heating system. The flue passage design, thermal pin pattern and consistent wall thickness of each casting ensure uniform heat transfer and reduced thermal strain which prolongs the life of the castings. Durable metal push nipples expand and contract with the indvidual boiler sections that they connect. No flimsy gaskets that may deteriorate and leak.

We've fine tuned natural draft cast-iron boiler technology to its most advanced state. With AFUE ratings to 84.78%, Galaxy keeps fuel costs low. It doesn't rely on complex technologies for its efficiency, so there's less to pay for now and less to go wrong. While other boilers become subject to performance and breakdown problems over the years, you can count on Galaxy for efficient, trouble-free performance.

Galaxy GG Series boilers are designed specifically for hot water heating systems. For other requirements, including tankless coils for domestic water, steam heating systems and low profile steam models, refer to the Galaxy GX-GXH-GXHA Series boilers. Altogether, there are 85 Galaxy boiler models in a variety of sizes and configurations to meet most heating requirements.
