Ducted vs. Recirculating: Which is Right for You?

The choice between a ducted and a recirculating system is one of the most consequential decisions you will make for your small kitchen. A ducted system vents air directly outside, meaning it completely evacuates heat, moisture, odors, and combustion products like carbon monoxide from your living space. This is the gold standard for air quality, especially if you cook with propane or enjoy high-heat frying.

However, cutting duct holes through walls or roofs compromises your insulation envelope and creates potential points for water leaks. Recirculating systems, on the other hand, require no exterior modifications and are incredibly simple to install. They pull air through grease and carbon filters before blowing it back into the room, meaning they capture particulate matter but leave heat and humidity behind.

Consider your typical climate and cooking style before deciding. If you live in a cold or humid environment where windows must remain closed, a ducted system is crucial for preventing mold. If you live in a dry climate, cook minimally, or cannot alter your vehicle’s shell, a high-quality recirculating system paired with an open window is a practical compromise.

• Ducted Pros: Removes humidity and heat; expels carbon monoxide; higher airflow capacity.
• Ducted Cons: Harder installation; compromises insulation; potential leak risks.
• Recirculating Pros: Zero exterior holes; easy DIY setup; preserves structural integrity.
• Recirculating Cons: Does not remove moisture or heat; ongoing cost of replacing carbon filters.

Sizing Your Ventilation for Small-Space Off-Grid Power

In an off-grid tiny home or RV, every watt counts, and your ventilation system must be sized to match your power budget. Standard residential range hoods run on 120-volt AC power and can pull significant wattage, which quickly drains inverter reserves. For true off-grid setups, prioritizing 12-volt DC appliances is often the most efficient pathway because it eliminates inverter conversion losses.

When analyzing performance, look at the CFM (Cubic Feet per Minute) rating relative to the power draw. A higher CFM rating moves more air but requires more power, meaning you must find a balance that suits your cooking habits. For small spaces under 300 square feet, a ventilation system with 150 to 300 CFM is generally more than adequate to refresh the air quickly.

To calculate your power needs, multiply the appliance’s amp draw by the hours you expect to run it daily to get the total Amp-hours (Ah). Running a 12-volt, 3-amp fan for one hour uses just 3 Ah, which is easily replenished by a small solar panel. Make sure to size your battery bank with enough buffer so that cooking a late-night meal doesn’t trigger a low-voltage alarm.

Installation Secrets for Tight RV and Tiny House Walls

Installing a range hood in an RV or tiny house presents unique structural challenges that standard home installations never face. RV walls are often thin laminates with aluminum or wood framing spaced irregularly, while tiny houses use 2×4 studs that limit duct routing. Before you make any cuts, you must locate structural studs and electrical wiring using a reliable scanner.

When cutting an exterior vent hole, always cut from the inside out to ensure your duct matches your interior cabinetry perfectly. Use high-quality butyl tape and marine-grade sealant on the exterior flange to create a watertight barrier against highway-speed winds and rain. If you run into a stud, it is often easier to use an offset duct adapter rather than trying to cut and reframe a load-bearing wall section.

Additionally, ensure your exterior vent has a built-in damper or damper flap to prevent cold drafts and pests from entering when the hood is off. Secure all ductwork with foil tape rather than duct tape, as the adhesive on standard duct tape degrades rapidly under kitchen heat. Taking these extra steps during installation prevents water intrusion, which is the single greatest threat to alternative dwellings.

Investing in the right kitchen ventilation system ensures your alternative home remains a healthy, clean, and comfortable sanctuary. With the proper balance of power, efficiency, and smart installation, you can cook with confidence, knowing your small-space investment is well-protected.
