Allied LS25 Unit Heater

The Allied LS25 is a separated-combustion gas-fired unit heater for commercial and light industrial heating applications. Drawing combustion air from outside the building, it delivers clean, efficient heat output while protecting indoor air quality — ideal for tightly sealed or sensitive environments. 

Durable heat exchanger, separated combustion design, and compact hanging configuration minimize installation complexity and long-term service requirements across a wide range of commercial heating applications.

Ideal for garages, warehouses, shops, and light industrial spaces where indoor air quality is a priority. Product information from LK Metal. Confirm heating capacity, gas supply, venting requirements, combustion air arrangements, and mounting clearances before selecting the heater for your space.
