Dayton 5PV50 Hydronic Unit Heater Horizontal 1100cfm

SKU CH-THX0-XBS8M

Horizontal hydronic unit heater delivers 1,100 cfm airflow with 72,000 BtuH steam and 52,300 BtuH water output

  • Horizontal airflow delivers 1100 cfm for wide-area coverage
  • Dual steam and water heating handles 72000 BtuH at 2 psi steam and 52300 BtuH at 200 F water
  • OSHA-compliant fan guard protects personnel around the 14 in fan
  • Compact 21 3/4 in height fits tight ceiling spaces
  • Threaded 1 1/4 in NPT connections simplify hydronic piping

Suspended Horizontal Hydronic Heater

This suspended horizontal hydronic unit heater mounts on walls or ceilings and directs airflow horizontally across the space. It is built for commercial and industrial settings that need a steady stream of heated air from a central steam or hot-water system. The OSHA-compliant fan guard adds a layer of safety for occupied areas.

1100 cfm Airflow with Steam and Water Ratings

At 2 psi steam the unit delivers 72,000 BtuH, while 200 °F water provides 52,300 BtuH. The 1100 cfm airflow moves that heat through the space, and the 5.3 gpm flow rate sets the hydronic demand. Output drops when supply temperatures fall below the rated conditions, so the heater is sized for design-day loads rather than mild weather.

Threaded Female NPT Connection and 14 in Fan

A 1 1/4 in threaded female NPT fitting connects the coil to the piping system without adapters. The 14 in fan runs on single-phase 60 Hz power at 1.4 A, simplifying electrical installation. The header-type coil and OSHA-compliant guard are integrated, so no separate accessory kits are required for basic operation.

Questions about this item

Will the 1 1/4 in NPT connections on this 1100 cfm heater match the pipe size on my existing boiler loop?

The unit uses a 1 1/4 inch threaded female NPT connection for both supply and return, so it will match piping of the same nominal size and thread standard.

How can I verify the heater is delivering its rated 72,000 BtuH at 2 PSI steam after installation?

Measure the steam pressure at the inlet to confirm 2 PSI, check that the fan draws 1.4 amps at 60 Hz, and verify the air temperature rise across the 14 inch fan matches the 1100 cfm rating.

Does the box include the OSHA-compliant fan guard and mounting hardware, or must I order them separately?

The OSHA-compliant fan guard is factory-installed on the 14 inch fan; mounting brackets and any piping adapters are not included and must be sourced separately.
