Speedway Motors Street Rod Heater

The Speedway Motors unit delivers a high heating output of 20,000 BTU, designed to warm water-cooled street rods and custom builds. Its compact under-dash footprint fits tight spaces, with dimensions around 9.5″ x 6.5″ x 4.5″ and a front-to-back depth of about 8″. A two-speed 12-volt fan offers adjustable airflow to suit varying climates, making it adaptable for early mornings and brisk drives. This heater supports rear exit hose connections for flexible routing in automotive installs.
Heating Rod Warming System (2-Piece)

This 2-piece set includes a Heating Rod and a Drying Rod, with the Heating Rod sized at 6×0.8 inches. It can heat quickly to about 42°C, offering fast warmth for compact spaces. A built-in temperature sensor stops heating at 42–45°C and restarts when needed, providing automatic safety cycling. The system is 100% waterproof and composed of non-toxic materials, making it suitable for environments where moisture and cleaning are considerations.
Dr Infrared Heater DR-238

This carbon infrared heater is designed for both indoor and outdoor use with IP55 rating. It offers clean, odorless infrared heat across three power settings (900W, 1200W, 1500W) and operates on standard 120V. A remote control provides convenient temperature and mode adjustments, making it suitable for garages, patios, and backyards where quick, efficient warmth is desired.
BEYOND HEAT Ceiling Mount Garage Heater

The BEYOND HEAT ceiling-mount heater uses dual quartz tubes to deliver focused radiant warmth with two selectable heat settings via a pull-string switch. Its design emphasizes space-saving installation, with the added benefit of an integrated halogen light that can be used independently of the heat for improved visibility in a workshop or garage. This unit suits garages, shops, and patios where ceiling-mounted heat is preferred.
Buying Guide: Key Purchase Considerations For Street Rod Heaters
- Heat output and space: Assess the square footage of the area to heat and choose BTU or wattage accordingly. Smaller cabins or under-dash installations need compact units with high efficiency, while garages and workshops may require higher BTU models.
- Power source and installation: Determine if the heater is designed for 12V vehicle installation, standard 120V electrical circuits, or hard-wired 240V setups. Under-dash automotive heaters should be compact and easily routed, whereas garage units may need permanent mounting.
- Indoor vs. outdoor use: For street rods that live in a garage or outdoor environment, IP-rated and weather-resistant models provide longer life and safer operation in varied climates.
- Temperature control and safety: Look for multiple heat settings, remote control, auto shutoff features, and safety protections such as temperature sensors or tip-over/overheat protection to reduce risk during extended use.
- Versatility and multi-function options: Some models pair radiant infrared heat with lighting or offer a mix of heat and fan configurations, giving flexibility for different seasons and tasks.
- Installation footprint and wiring: Consider mounting options (under-dash, ceiling, wall) and whether professional installation is advisable, especially for hard-wired or high-wattage units.
- Maintenance and cleaning: Waterproof or easy-to-clean components are advantageous in environments where dust, grease, or moisture may be present.
