HSI ‘Resisto-Flo’ Hot Water Boilers are designed to provide fast,efficient and economical hot water for heating through the use of electric resistance elements. The boiler controls automatically energize/de-energize steps of elements to maintain the desired water temperature. All HSI Hot Water Boilers utilize ASME pressure vessels (Section IV up to 160 psi; Section VIII above 160 psi) and all electrical components are UL listed and are wired in accordance with the current National Electrical Code requirements.

Each boiler is insulated with 3-1/2" fiberglass secured to the vessel, and is housed in an enameled heavy-gauge sheet metal cabinet mounted on a full-size structural steel base. All HSI ‘Resisto-Flo’ boilers utilize 70 wpsi Incoloy-sheathed elements configured in conservatively-sized circuits to allow for overvoltage conditions as great as 10% without adversely affecting the integrity of circuit components.
