FAQs

Your unit heater and make-up air unit questions, answered.

A unit heater is a self-contained heating device designed to warm specific areas or rooms. It typically consists of a heat exchanger, fan, and housing, and can be powered by electricity, gas, or hydronic systems. Unit heaters are commonly used in commercial, industrial, and residential settings to provide efficient and targeted heating.

Unit heaters operate by drawing in air, heating it through a heat exchanger, and then distributing the warmed air into the space using a fan. Depending on the type of unit heater, the heat exchanger can be powered by electricity, gas, or hot water/steam in hydronic systems. This process ensures consistent and effective heating, making unit heaters a reliable choice for maintaining comfortable indoor temperatures.

A make-up air unit is an HVAC system designed to introduce fresh, conditioned air into a building to replace air that has been exhausted. These units are essential for maintaining indoor air quality and ensuring proper ventilation in commercial and industrial spaces.

    A make-up air unit works by drawing in outside air, filtering it, and conditioning it to the desired temperature and humidity levels. The conditioned air is then distributed throughout the building to replace the air that has been exhausted by ventilation systems. This process helps maintain balanced air pressure, improves indoor air quality, and ensures a comfortable environment for occupants.
