FIELD: equipment heating gases or single-phase liquids. SUBSTANCE: invention is meant for low-temperature gas heating used in many branches of industry, for instance, in gas industry to heat natural gas at inlet of gas distribution station. Objective of invention lies in design of high-reliability gas heater showing long service life thanks to uniform heating of heat-exchange surface with prevented condensate formation. Proposed gas heater has body with heat-exchange module coming in the form of internal and external tubes. Heat-exchange module is oriented vertically with reference to body and inlet and outlet collectors are oriented horizontally with respect to heat-exchange module.
