- It supports multi-fuel operation (kerosene, #1/#2 fuel oil, diesel, jet fuel) with a 10-gallon tank.
- Typical fuel use is roughly 1 gallon per hour, providing up to ~10 hours of runtime depending on conditions and load.
- Electronic one-touch start and thermostat modulation improve comfort control versus simple cycling heaters.
- Built-in flameout, overheat protections, and LED diagnostics help identify combustion or temperature issues quickly.
What 135,000 BTU Means for Real Garage Heating
How much heat do you really get from 135,000 BTU in a garage? For garage heating math, treat that as peak output: 135,000 BTU/hr ≈ 39.6 kW. In practice, your heat loss dictates delivered warmth, especially if walls and doors leak. With forced-air circulation, you can move heat across roughly 3,200 sq ft, but set expectations for uneven temperature near vents. For fuel cost planning, pair output with consumption: about 1 gallon/hr. That means 10 gallons covers ~10 hours, so runtime economics depend on your local kerosene or diesel price—emergency preparedness matters because dependable heat can be critical during winter outages.
Reddy Heater RFA135CV-2 Fuel Options and Runtime
Reddy Heater RFA135CV-2 runs on multiple fuels—kerosene, #1/#2 fuel oil, diesel, and even jet fuel—so you can match supply and price without changing the heater. You get a 10-gallon fuel tank capacity that supports roughly 1 gallon per hour consumption, giving up to a 10-hour maximum operating window. In practice, your extended run time depends on ambient conditions and load, so size fuel logistics for shift work. When you refuel, keep fuel types consistent for stable combustion and predictable output. Also, choosing a fuel source you can reliably restock helps you plan colder-weather readiness for family, friends, and anyone who needs dependable heat during outages or long stretches outdoors with compatible fuel types.
How the Electronic Start and Thermostat Perform
The heater’s multi-fuel runtime only matters if it can regulate ignition and output reliably, and the Reddy Heater RFA135CV-2 focuses on that with an electronic one-touch start plus an electronic thermostat. You press once, and the ignition sequence stays consistent, supporting Electronic reliability across kerosene or diesel-like fuels. Then you set your target temperature; the thermostat modulates burner output rather than cycling blindly. That gives you tighter Comfort control in garages and workshops where door openings and drafts swing room temperature. Practically, you’ll notice steadier warm-up maintenance during long work sessions. This helps you cozy heating pads readiness as the weather turns colder.
Reddy Heater RFA135CV-2 Safety Features and Diagnostics
Safety and diagnostics on the Reddy Heater RFA135CV-2 give you multiple layers of protection while you run it in high-activity spaces. You rely on flameout protections to shut down quickly if combustion becomes unstable, reducing the risk of unsafe venting. You also benefit from overheat safeguards that monitor operating temperature and interrupt firing before heat stress builds. For troubleshooting, the heater’s LED digital diagnostics show temperature and error codes, so you can pinpoint faults fast. In practice, you watch the status display during startup and recheck codes immediately after any shutdown. If you’re using any gas heater in colder months, carbon monoxide detection is an important companion safety step to consider.
Who the RFA135CV-2 Is Best for and Why
If you need high-output heat for demanding work areas, the RFA135CV-2 fits best because it combines 135,000 BTU forced-air performance with multi-fuel capability and electronic controls. You’ll like it if you work in garages, workshops, warehouses, or active construction sites where Construction Flexibility matters. The 500 CFM airflow supports Large Space Recovery, bringing big rooms back to operating temperature quickly. Choose it when fuel sourcing varies: it runs kerosene, #1/#2 fuel oil, diesel, or jet fuel. With one-touch electronic start, thermostat control, and diagnostics, you reduce downtime. It also aligns with propane heater preparedness goals by helping you maintain reliable backup heat during colder weather.
Some Questions Answered
What’s the Noise Level While the 500 CFM Fan Runs?
You can expect moderate operational noise from the 500 CFM forced-air fan, typically in the mid-to-high dB range, but the exact fan noise frequency and decibel level aren’t published for the RFA135CV-2. In practice, you’ll hear a steady blower hum plus ignition cycling. For best results and to reduce perceived noise, keep proper Outdoor installation clearance, avoid enclosed spaces, and place it on stable flooring.
Does It Require Ventilation or Can It Run in a Sealed Garage?
You shouldn’t run this kerosene forced-air heater in a sealed garage. It needs adequate ventilation because combustion consumes oxygen and exhaust can produce carbon monoxide. For safe garage operation, place the unit outdoors or provide directed ducting to the outside, and install CO monitoring. Follow the manual’s clearance and exhaust requirements exactly. Use fresh air intake and keep doors cracked; don’t rely on “indoor-rated” claims alone.
How Often Should the Fuel Filter and Nozzle Be Serviced?
You should service the Fuel filter about every 250–500 hours of operation, then inspect sooner if you see poor ignition, odor changes, or uneven heat. You should perform nozzle cleaning on the same schedule or whenever you run contaminated fuel. Run performance checks after each service: confirm stable flame, correct temperature output, and no flame-out codes on the LED diagnostics. Always follow your heater manual for exact service intervals.
What Ignition Type Prevents Starting Issues in Cold Temperatures?
You’ll get reliable cold-weather starts because it uses a Pilot spark ignition system, which keeps the burner ready to light quickly even when temperatures drop. That design reduces misfires and starting delays compared to older glow or hot-surface methods. It also supports consistent combustion, which helps maintain stable performance while limiting operational instability; Noise control remains stable by avoiding repeated ignition cycles.
Are There Specific Approved Fuels to Avoid Damage or Soot Buildup?
Use only the heater’s approved fuel guidance: kerosene, #1 and #2 fuel oil, diesel, or jet fuel. Avoid unleaded gasoline, alcohol blends, and waste fuels, since they can raise particulate formation and increase soot risk. For soot prevention, keep clean fuel, use fresh fuel, and don’t dilute with additives unless the manufacturer explicitly approves them. Stick to the stated fuel and you’ll minimize deposits and maintain combustion stability.
