Horizontal Hydronic Unit Heaters, Water Or Steam Heating

Dayton horizontal hydronic unit heaters mount on walls for heating large areas, commercial and industrial spaces. These heaters feature threaded female NPT connections for the supply of water or steam to heat the air and have fans to push & spread the heated air horizontally. They come with adjustable louvres for controlling the direction of airflow. Selected models allow vertical mountingon the ceiling to push the heated air downward towards the floor. Choose from a wide range of these heaters, available in airflow speeds ranging from 395 to 5500 cfm.

Suspended Vertical Hydronic Wall & Ceiling Unit Heaters

Dayton suspended vertical hydronic heater units provide primary or supplementary heating by pushing and spreading the heated air. They are suspended from a wall or ceiling to spread the air evenly. These units store water, which is then heated by passing a current through rectangular coils and circulated with a maximum rate of 75 PSI. They feature a totally enclosed motor capable of producing a maximum power output of 3 HP. The heater units are ETL & ETLc listed and complies with OSHA standards for safe use. Choose from a wide range of unit heaters, available in single and three phase variants on Raptor Supplies.

Hydronic Unit Heaters

Hydronic unit heaters utilize non-potable hot water or steam produced by a boiler, indirect water heater. Dayton heaters save floor space and are therefore commonly used in large areas like manufacturing facilities, warehouses and garages. These heaters are capable of pushing heated air horizontally and vertically and spread it across a larger area. Choose from a broad range of these Dayton hydronic heating units, available in 11000 cfm, 500 cfm, 450 cfm, 395 cfm and 245 cfm air flow options.

Features

  • Dayton water & steam heated horizontal hydronic unit heaters come with fans to spread & push the heated air horizontally. These heaters have threaded female NPT connections to supply water / steam for heating the air and are equipped with adjustable louvres to control the direction of airflow. They can be mounted on walls for heating industrial spaces.
  • Dayton suspended vertical hydronic heaters are mounted on the ceiling or wall vertically to spread the air evenly. They feature a totally enclosed motor for protection from dust and have a maximum operating pressure of 75 PSI. These heater units are ETL & ETLc listed and comply with OSHA standards for safe & secure operations.
  • Dayton water heated horizontal hydronic unit heaters are suspended from a wall / ceiling horizontally to spread the air evenly. These units heat the stored water by passing a current through serpentine coils.

Working Mechanism

  • Hot water is produced by a central boiler for heating the water to the required temperature.
  • The hot water is then circulated through a series of heating coils / radiators within the unit heater.
  • The heat from the hot water is then transferred to the surrounding air through the heating coils.
  • A fan or blower inside the unit heater circulates the warm air into the heated space.
  • The cooled water then returns to the central boiler for reheating and the cycle repeats.
  • The temperature of the hot water is then controlled by adjusting the temperature setting on the central boiler and the amount of heat produced by the unit heater can be adjusted by controlling the flow of hot water through the heating coils or radiators.

Frequently Asked Questions

What is the flow rate of Dayton hydronic unit heaters?

The flow rate of these heaters range from 245 to 11000 cfm.

What safety precautions should be taken when using hydronic unit heaters?

  • Get the system installed by a qualified technician.
  • Inspect the central boiler regularly and maintain it to ensure safe operation.

What is the role of a thermostat in hydronic unit heaters?

The thermostat controls the temperature of the hot water and the rate of heat transfer. The thermostat is set to the desired temperature and will turn the unit on and off as needed to maintain the required temperature.
