Description
Overview SunStar SPH100-30-L7 is an SPH Series infrared gas radiant tube heater designed for nonresidential comfort heating. It uses a 30 ft body in a push-through, positive pressure tube heater configuration. Rated at 100,000 BTU/hr high input with 65,000 BTU/hr low input capability to support coverage planning for commercial spaces. This model is configured for propane with two stage operation and direct spark ignition. Vented and indirect vented operating modes are supported to align with building ventilation strategies.
Performance Heat delivery is based on infrared radiation from the emitter tube and reflector assembly rather than high air movement. Emitter tubes are calorized steel to support higher radiant efficiency and corrosion resistance. The emitter tube terminates inside the reflector body and discharges products of combustion under the reflector to increase return tube temperature. This construction supports stable tube temperatures along the heated line when suspended horizontally. A 4 in flue connection and 4 in outside combustion air connection support integration with venting and combustion air ducting where required.
Smart Features Control is thermostat-driven and supports either low-voltage (24V) or line-voltage (120V) thermostat wiring configurations. Two-stage models use high/low fire control logic to better match changing load conditions within a zone. Optional timer/switch control kits are available to add scheduled operation for individual heaters. An optional two-stage relay board supports multi-heater staging and coordinated control schemes. These control options help align run time and staging with occupancy patterns and operational schedules.
Comfort & Noise Radiant heat focuses energy toward people and surfaces, supporting comfort in high-ceiling and open-area layouts. The blower is enclosed inside the burner box with no exposed exhauster motors, supporting quieter operation and reducing maintenance exposure. Minimum mounting height guidance for horizontal suspension is 14 ft for this input size as a planning baseline for indoor applications. A two-point tube suspension system with external frame brackets supports consistent alignment along the heater run. Where building pressure or air quality requires it, outside combustion air can be ducted directly to the burner box.
Use Case Fit The SPH Series is specifically positioned for golf ranges and hospitality applications where infrared comfort heat is preferred. Applications also include covered patios and restaurant environments where targeted radiant heat supports occupied zones. The heater is intended for nonresidential spaces and is suited to layouts that benefit from suspended, linear heat distribution. Choose propane fuel to match site utilities and 30 ft body length to match the planned heater spacing and coverage geometry. Vented discharge can be routed outdoors, while indirect vented operation can be used when code-required building ventilation is provided.
Value & Reliability Calorized steel emitter tubes and reflector-based heat delivery support consistent radiant output with corrosion resistance. The enclosed blower location supports service access at the burner box while keeping moving components protected. Standard connections include a 1/2 in NPT gas connection, 120V power supply, and direct spark ignition controls. Design-certified construction supports repeatable specification across projects and heater counts. Defined mounting and clearance guidance helps contractors and facility teams maintain consistent layouts during installation planning.
Summary Wrap-Up: SunStar SPH100-30-L7 combines the SPH Series push-through tube heater platform with the BTU input and staging needed for commercial comfort heat. Select the fuel type and stage option that best match site utilities and load variability, then size body length for the coverage plan. Direct spark ignition and thermostat-driven control support predictable operation in hospitality and open-area environments. Vented or indirect vented configurations provide flexibility for different building ventilation approaches. This SKU is a practical choice for buyers and contractors who want a standardized infrared heater platform for both wholesale and direct purchase workflows.
