GXH and GXHA steam boilers are available with or without tankless heaters. Low profile GXHA steam models fit in locations with reduced overhead clearance. For models designed specifically for hot water heating systems, refer to Galaxy GG Series models. All together, there are 85 Galaxy boiler models in a variety of sizes and configurations to meet heating requirements.

Cast-iron confidence; Field proven reliability

Galaxy is a highly reliable natural draft boiler that means business. It connects to a chimney and needs no fans nor power combustion devices, making it a simple and reliable boiler. Its cast-iron design is recognized by heating professionals everywhere as the longest lasting, most durable heat exchanger material. Galaxy’s cast-iron heat exchanger sections are joined together with durable metal push nipples, and specially shaped thermal pins promote efficient heat transfer. With fewer components, there’s less chance of losing your heat because of component failure. The boiler heats quickly, sending warmth to radiators throughout your home within moments of your thermostat’s call for heat. Galaxy boilers are so reliable, they are backed by a lifetime limited hot water or 1 year steam warranty.

Galaxy Steam models

Galaxy Steam models are the industry’s best solution to system noise and boiler maintenance problems. High efficiency models, with intermittent pilot and vent damper, are also among the most efficient steam boilers you can buy. The Galaxy produces dry steam and delivers it to system through a 2 1/2″ supply tapping. This ensures lower steam velocity and quieter system operation. The speed skimmer trough built into Galaxy “PZ” steam boilers makes cleaning the boiler water easy by skimming the surface films of grease, oil, and other contaminant’s.

Low profile GXHA models

A built-in integral draft diverter on the four GXHA models reduce clearance requirements above the boiler to 18″, making them ideal for use in locations with low chimney breaching or with overhead obstructions.
