The Thermaflo TH-750V "IronHorse" Steam Fired Water Heaters are designed for years of trouble free hot water on demand. These high quality packages are factory steam tested before shipment to ensure quick “Fit and Forget” start ups and installation. Factory packaging and live steam testing keeps contractor and customer installation time to a minimum. Their simple compact design allows them to be installed in tight spaces and replace those old oversized hot water storage tanks. All sizes fit thru a 30” doorway.
  Thermaflo Engineering utilizes their exclusive single seated type balanced trim steam control valve with “Thermall” soft seat to provide exceptional control over high and low water flow demand changes. The “Seals like Rubber - Wears like Hardened Steel” seat shuts off steam dead tight on long standby type loads and no demand periods like no other! All Thermaflo TH-750V Heaters can be fitted with a condensate sub-cooling option to eliminate flash steam increasing overall unit efficiency of both latent and sensible heat BTUs. All Thermaflo TH-750V Heaters are constructed and stamped in accordance with Section VIII, Div 1 of the ASME code.
