Transform Your Tent Heater into Full-Tent Warmth

If you’ve ever heated a winter tent, you already know the problem.. Your heater is blasting away… but only the ceiling gets warm. Meanwhile your floor, sleeping bag, and toes stay freezing cold. You burn more fuel, crank the heater higher, and still the warmth never reaches where you actually are.

What if you could turn that same heater into a full-tent heating system, one that pushes warmth downward, circulates it evenly, and makes your whole shelter feel comfortable…
all without using a single watt of electricity?

That’s exactly why the TUF Heat-Powered Stove Fan MK2 exists. Engineered by turbomachinery researchers and powered only by heat, TUF captures wasted rising heat and sends it back down into your tent, warming your feet, your sleeping area, and every corner that used to stay cold.

For winter campers, overlanders, and ice-fishing diehards, this isn’t just another camp gadget.
It’s the missing piece that finally makes your heater work the way you always wished it would.

Thermoelectric Generator

The TUF MK2 uses a built-in thermoelectric generator that turns your heater’s heat into electricity-no batteries or power needed! 🔌 When you place it on top of your stove, the bottom heats up while the heatsink stays cooler. This temperature difference creates clean, self-generated power that drives the fan motor.

The result? A strong downward airflow that pushes warm air from the ceiling back down to the floor—circulating heat evenly and making your entire tent feel warmer, faster, and far more comfortable.

High-End Motor, Proven Reliability

What makes the TUF MK2 feel so smooth and quiet is its premium brushless motor, built for stability, durability, and cold-weather reliability.

Unlike low-output motors found in cheaper heat-powered fans, the TUF MK2’s motor delivers steady, vibration-free rotation, which means consistent airflow, quieter operation, and long-term performance you can trust in harsh winter conditions.

This motor has been proven through three years of real outdoor use, from subzero hot-tent trips to ice-fishing shelters, without issues like noise, wobbling, or weak airflow. It’s engineered to run cleanly and efficiently, powered entirely by the MK2’s thermoelectric generator.

• Max No-Load Voltage: 14.4V
• Max Output: 22W

Hyper Swirl+ Airflow Technology

The TUF MK2 uses a turbine-inspired Outlet Guide Vane (OGV) system, normally found in high-performance engines, to shape and control the airflow coming off the fan blades.

This engineered vane structure creates a strong swirling downward airflow, known as the Hyper Swirl+ effect.

Instead of letting warm air drift upward and disappear at the ceiling, the MK2 pushes it powerfully back down into your living space.

The result is significantly faster heat circulation, fewer cold spots, and a warmer, more comfortable tent—no matter how cold it is outside.

Engineered for Perfect Balance

Every part of the TUF MK2 is designed with one purpose in mind: deliver smoother airflow, stronger stability, and a premium feel that lasts for years of real outdoor use.

The MK2 features a 4-point top-grill structure, built to keep the fan perfectly level and securely seated on your heater. This balanced design minimizes vibration, improves smooth rotation, and ensures consistent airflow even during long heating sessions.

Its frame takes inspiration from turbofan engine architecture - strong, symmetrical, and built for precision.
The result is a fan that not only performs reliably but also feels solid and premium every time you pick it up.

Optimized Top Grill for Smoother, Stronger Airflow

The top grill of a heat-powered fan is its air intake, so its shape matters.

The TUF MK2 uses a concave, inward-bent top grill that allows air to flow smoothly into the fan while giving you a secure, comfortable grip when lifting or repositioning the unit.

The inward shape also minimizes unnecessary gaps, creating a cleaner, more cohesive structure that improves both airflow and durability.

Thicker grill rods provide added strength, ensuring the MK2 stays stable on your heater and can be carried with confidence.

Built for real outdoor use, this top grill design enhances airflow performance while offering the solid, premium feel you expect from a winter-ready tool.

Built-in Handle

The TUF MK2 features a built-in handle that greatly improves portability and ease of transport.

To achieve the ideal shape and structure for the new top grill, we tested dozens of design variations and ultimately created a simple, durable, and detachable handle system.

Made from high-strength SUS steel and finished with heat-treatment and plating, the handle is engineered for both durability and safety—allowing you to carry the TUF MK2 easily and securely.

Heat-Resistant Silicone Pad for Safe Cooling

The TUF MK2 includes a heat-resistant silicone pad designed for safe placement after use.

Over three years of sales and after-service support, we found that many users placed a hot TUF on ground sheets, carpets, or the TUF lid, often causing melting or sticking due to the high temperature of the base.

When removing the TUF from your stove, especially inside a tent with a ground sheet, it’s not always clear where to safely set it down. To eliminate this concern, we developed a dedicated silicone pad that withstands high heat and prevents damage to surfaces.

Simply place the TUF on the silicone pad after use to let it cool safely. The pad can be stored inside the EPP case, set on the lid, or placed anywhere convenient for cooling.

Durable EPP Hard Case Included

The TUF MK2 comes standard with a hard case made from eco-friendly EPP (Expanded Polypropylene), the same highly durable material used in automotive bumpers and protective helmets. This EPP case shields the TUF from external impacts and shocks that can occur during transport or camping.

The square-shaped design improves storage efficiency, includes a shoulder strap, and features dedicated grooves for mounting the Boosting Skirt. Beyond protection, the hard case can also be repurposed as a cooler box, battery storage, or thermal container, adding versatility to your camping setup.

TUF Boosting Skirt V2

A performance-enhancing accessory designed to help your TUF MK2 spin faster, circulate heat more efficiently, and warm larger spaces more evenly.

Made from heat-resistant anodized aluminum, V2 delivers stronger durability, stable placement, and improved heat capture, perfect for winter camping setups that need maximum performance.

📌 The TUF operates normally without the skirt, circulation and fan rotation work fine. However, using the skirt provides faster startup, higher RPM, and a wider radiation angle, which is especially helpful in larger tents or indoor spaces.  For spacious environments, we recommend using the skirt.

Enhanced Start-Up & Stronger Airflow

The Boosting Skirt was developed to improve the TUF MK2’s rotation performance and minimize start-up time. By guiding the rising heat from the sides of the kerosene heater more efficiently into the thermoelectric module, the skirt ensures faster ignition, higher RPM, and stronger airflow from the very beginning.

This upgrade allows the TUF to deliver its full performance more quickly, especially valuable in cold winter conditions or when heating larger tents.

Wider Heat Radiation for Better Circulation

The Boosting Skirt reduces the amount of heat that escapes upward along the sides of the heater and instead expands the radiation angle outward. This allows warmth to spread farther and more evenly through your space, upgrading the TUF MK2’s overall heating efficiency.

With a wider, more effective airflow pattern, the TUF offers improved comfort even in spacious tents or cold environments.

📌 It can only be used on heaters where the skirt sits lower than the top plate.
📌 It cannot be used on models where side guards or structures sit higher than the top plate (e.g., Toyotomi DC-100).

Premium Anodized Aluminum Construction

The ConvecVane® Boosting Skirt is crafted from anodized aluminum, a material chosen for its exceptional strength, heat resistance, and long-term durability. Anodizing creates a hard, corrosion-resistant surface that protects the skirt from high stove temperatures, outdoor humidity, scratches, and long-term wear.

Unlike painted or coated parts, anodized aluminum won’t peel, bubble, or discolor, even after repeated heating cycles. This material also keeps the skirt lightweight while maintaining structural rigidity, ensuring stable operation on the heater without warping or bending.
