Arctic Condensing (ARC) - Ultra High Efficiency Hot Water Boilers

Check up to five results to perform an action.

The Arctic Condensing Boilers use flexible watertubes that have long been the workhorse of the boiler industry, naturally flexing and moving with expansion & contraction that occurs in heating. These tubes are unrivaled at absorbing and transferring the intense heat of today’s burners into water and distributed as heat.  Thermal Solutions uses no welds in mechanically sealing tubes to header and provides a lifetime warranty on this seal.  With no welds, the Arctic permits field access for tube replacement making it the only field repairable heat exchanger in the condensing market.  The Arctic is available fully packaged, or if required, knockdown for ease of onsite maneuvering and assembly, another industry first!
