Suspended Hydronic Unit Heater
The Dayton 5PV35 is a suspended horizontal hydronic heater designed for wall or ceiling mounting. It delivers heat using steam or hot water through a header-type coil with threaded female NPT connections. The unit operates on single-phase power at 60 Hz and draws 4.5 A. An 18 in fan with an OSHA compliant guard moves air horizontally across the coil.
Installers needing high-output hydronic heat
This heater suits commercial or industrial spaces that require 204 000 BtuH at 2 PSI steam or 148 000 BtuH at 200 F water with a flow rate of 14.9 gpm. The 24 5/8 in width and 13 3/4 in depth fit between standard structural members. Buyers who need vertical discharge, electric heat, or a smaller footprint should look at other configurations.
29 in overall height constraint
The cabinet measures 29 in tall, 24 5/8 in wide and 13 3/4 in deep, so the available mounting clearance decides whether this model fits. The 1 1/2 in connection size must match the existing piping. Confirm the height allowance and pipe diameter before ordering.

Questions about this item
How do I install the 1 1/2 in threaded female NPT connections on this hydronic unit heater?
Thread the supply and return piping into the 1 1/2 in threaded female NPT connections using pipe sealant rated for steam or hot water. The step often missed is verifying the header coil orientation matches the flow direction arrow on the casing before tightening.
What maintenance will the 18 in fan with OSHA compliant guard need over time?
Inspect the 18 in fan blades and OSHA compliant guard annually for dust buildup or corrosion. Clean the blades to maintain the 2.900 cfm airflow and check the 4.5 A motor current; replace the motor if amperage rises above nameplate rating.
At what output limit does the heater max out during continuous steam operation?
At 2 psi steam the coil delivers 204,000 BtuH with a 14.9 gpm flow rate. That thermal capacity is the first limit reached under sustained use; the 1 hp single phase motor at 60 Hz cannot push more than the rated 2.900 cfm across the header coil.
