19,107 BTU/h Heating Performance for Supplemental Space Heating

The TPI Corporation HF686TC provides a maximum heating output of 19,107 BTU/h at 240 V and 14,330 BTU/h at 208 V. Its rated electrical input is 5,600 W at 240 V or 4,200 W at 208 V, making it suitable for supplemental heating in appropriately sized indoor spaces. Manufacturer-published specifications list a temperature rise of approximately 75°F under the specified test conditions. Actual room temperature performance depends on ambient temperature, insulation, air infiltration, room dimensions, and other environmental factors. Select the operating voltage and heater capacity according to the available electrical supply and the heating requirements of the intended application.

Finned Steel Tubular Electric Heating Technology

The TPI Corporation HF686TC uses a finned steel tubular heating element to convert electrical energy into heat. As the element warms, the integrated fan moves air across the heated surface, transferring thermal energy into the surrounding space. This fan-forced design distributes heat without requiring a fuel supply, combustion burner, or combustion exhaust system. The heater operates on a compatible 208 V or 240 V, single-phase electrical supply. Install and operate the unit in accordance with the manufacturer's instructions, required clearances, and applicable electrical and building codes.

262 CFM Airflow & Forced-Air Heat Distribution

The TPI Corporation HF686TC delivers approximately 262 cubic feet per minute (CFM) of airflow, with a published air throw of approximately 10 feet. The integrated fan circulates heated air away from the unit to support localized temperature control and supplemental space heating. Its forced-air operation helps distribute warmth beyond the immediate surface of the heating element. Maintain unobstructed air intake and discharge openings, and position the heater to allow adequate air circulation. Do not cover the heater or obstruct airflow during operation.

Compact Design & Flexible Mounting

The TPI Corporation HF686TC features a compact housing measuring approximately 13.5 inches wide, 17.5 inches high, and 11.5 inches deep. Its approximate operating weight is 20 lb. The swivel base accommodates wall, floor, or ceiling mounting in approved configurations, allowing the heater to be positioned according to the available space and intended heat distribution. The unit can be positioned as permitted by the manufacturer's instructions or secured using an appropriate mounting arrangement. An optional wall/ceiling mounting bracket, catalog number A1560, is listed in the manufacturer's documentation for compatible 680 Series and ICH 240C Series heaters. Confirm compatibility with the HF686TC before ordering. Ensure that the supporting surface or structure can accommodate the heater and that all required clearances are maintained.

Electrical Power & Energy Consumption

The TPI Corporation HF686TC operates on a 208 V or 240 V, single-phase electrical supply and is rated for 50/60 Hz operation. Its electrical input is 4,200 W at 208 V and 5,600 W at 240 V. Manufacturer-published current ratings are approximately 20.2 A at 208 V and 23.3 A at 240 V. The unit is supplied with a 6-foot power cord and a molded NEMA 6-30P plug, as specified for the HF685TC and HF686TC models in the manufacturer's 680 Series catalog. Verify the receptacle, circuit capacity, overcurrent protection, grounding, and connection requirements against the heater nameplate and current manufacturer's documentation before installation. Do not connect the heater to an incompatible receptacle or electrical supply. Electrical work must be performed by appropriately qualified personnel in accordance with applicable codes.

Controls, Comfort & Temperature Management

The TPI Corporation HF686TC incorporates a temperature-control thermostat with a published adjustment range of approximately 60°F to 110°F. This integrated control allows the user to regulate heating operation according to the surrounding temperature. The heater also incorporates an internal manual-reset thermal cut-out to help protect against overheating. Maintain adequate airflow around the unit and follow the manufacturer's reset and troubleshooting instructions if the thermal protection activates. Do not bypass or disable the thermal cut-out. Disconnect power before inspecting the unit or performing maintenance.

Commercial, Workshop & Industrial Applications

The TPI Corporation HF686TC is intended for suitable indoor applications requiring supplemental electric heat. Potential applications include workshops, garages, maintenance areas, utility rooms, and other appropriately sized indoor workspaces with a compatible electrical supply. Its 5,600 W maximum input at 240 V, adjustable thermostat, and flexible mounting base support a variety of suitable heating arrangements. The fan-forced design helps circulate heated air into the surrounding area, while the electric heating configuration eliminates the need for onsite fuel storage or a combustion exhaust system. Confirm that the intended location, electrical supply, mounting arrangement, and clearances comply with the manufacturer's requirements and applicable safety regulations.

Mounting Flexibility & Deployment

The TPI Corporation HF686TC features a swivel base designed to accommodate wall, floor, or ceiling mounting in approved configurations.
