Infratech SL-4024 Slimline 4,000W Electric Patio Heater
Clean architectural design meets powerful outdoor comfort with the Infratech SL-4024 Slimline Electric Heater. Delivering 4,000 watts of infrared heat from an exceptionally narrow 63.5-inch housing, the SL-4024 provides comfortable radiant warmth without dominating the design of your outdoor space.
Designed for covered patios, outdoor kitchens, terraces and upscale entertaining spaces, the Slimline Series warms people and surrounding surfaces directly rather than relying on heated air. The result is quiet, clean and efficient comfort with no open flame, fuel tank or fan.
Why Choose the SL-4024?
- 4,000W infrared output — delivers 13,653 BTUs of radiant heat for comfortable outdoor living.
- Ultra-slim architectural profile — keeps the heater visually unobtrusive in finished patios, pergolas and outdoor kitchens.
- 63.5-inch heater length — provides a broad heating platform while maintaining the streamlined Slimline appearance.
- Single-element design — delivers direct radiant warmth without fans or moving parts.
- 240V electric operation — eliminates propane tanks, natural gas connections and open flames.
- Control flexibility — compatible with an Infratech On/Off control or eligible Infratech Custom Control system.
Slimline Design
The SL-Series is designed for outdoor spaces where heating performance matters without compromising the architecture. Its narrow housing and clean lines allow the heater to blend naturally into covered patios, outdoor kitchens and other finished outdoor living environments.
The SL-4024 features 304 stainless steel construction with an anodized aluminum housing. Choose the standard stainless-hue appearance or the All Black Slimline Shadow™ for darker ceilings and contemporary installations.
Control Required
Important: The SL-4024 requires a separate compatible control. A control is not included with the heater. Infratech lists the SL-4024 for use with an appropriate On/Off control or Custom Control system. The standard Input Regulator is not listed for this 4,000W model.
Recommended Value Control
As a single-element Slimline heater, the SL-4024 is best paired with Infratech's Single On/Off Switch — the manufacturer's recommended value control for C-Series and Slimline SL heaters. For app-based, smart operation, the Enhanced Timer Control (compatible with any Infratech heater series) adds a digital timer and Bond app control. An Infinite Control Regulator is also compatible with single-element heaters like this one for adjustable heat intensity.
Installation
The SL-4024 is a permanently installed 240V electric heater and should be installed by a qualified electrical professional. Heater placement, electrical requirements, mounting clearances and control configuration must follow current Infratech installation instructions and applicable local electrical and building codes.
