1. MotoAlliance Firestorm 2.0 Heater Kit: Best Overall
In our evaluation, the MotoAlliance Firestorm 2.0 stands out as the top performer. Based on owner feedback and the spec sheets, this 25,000 BTU heater delivers exceptional warmth even in subzero temperatures. The three-speed fan allows you to adjust airflow, and the included defroster vents are a thoughtful addition for safety. Build quality is robust with an aluminum core and powder-coated housing that resists rust.
However, installation requires some mechanical skill and may take a few hours on certain UTVs. The wiring harness is straightforward, but routing hoses can be tight in smaller cabs. This heater is best for owners who prioritize maximum heat output and don’t mind a more involved install. If you have a very small cab or only need occasional warmth, a lower-cost option might suffice.
- High heat output of 25,000 BTU warms cab quickly even in extreme cold
- Compact design fits most UTV models with universal mounting brackets
- Integrated defroster vents keep windshield clear for safer driving
Pros: Excellent heat output and airflow; Durable aluminum construction resists corrosion; Includes all necessary mounting hardware and wiring
Cons: Installation can be time-consuming on some models
2. Kolpin UTV Heater Kit 25-0140: Runner Up
The Kolpin 25-0140 is a solid runner-up that we found to be one of the best value options. Our research shows that its 20,000 BTU output is sufficient for most cold-weather riding, and the universal fitment means it works with a wide range of UTVs. Owner reviews frequently praise the straightforward installation and the quiet operation on the low fan setting.
The main drawback is the lack of integrated defroster vents. You’ll need to buy or rig a separate defroster if you ride with a windshield. Also, the plastic housing feels less premium than aluminum competitors. This heater is ideal for budget-conscious buyers who want reliable heat without breaking the bank. Skip it if you need a defroster or plan to ride in extreme cold below -20°F.
- 20,000 BTU output provides ample heat for most side by sides
- Universal design with adjustable brackets fits Polaris, Can-Am, Kawasaki, and more
- Two-speed fan allows quiet operation on low setting
Pros: Good balance of performance and price; Simple installation with clear instructions; Reliable brand with good customer support
Cons: No defroster vents included
3. Heat Demon 700-100 UTV Heater: Best Compact

The Heat Demon 700-100 is designed for UTVs with limited space. In our evaluation, its compact footprint allows it to mount under the dash or even under the seat without interfering with passenger comfort. The 15,000 BTU output is enough for mild to moderate cold, and the two-speed fan provides adequate circulation. Owner feedback highlights the ease of installation thanks to the quick-connect hose fittings.
However, the lower BTU rating means it struggles in very cold conditions below freezing. The plastic housing is less durable than metal units, and some owners reported that the fan can be noisy on high speed. This heater is best for riders in warmer climates or those who only need occasional heat. If you regularly ride in snow and ice, consider a higher-output model.
- Compact size fits easily under dash or seat without taking up legroom
- 15,000 BTU output is ideal for smaller cabs and moderate climates
- Quick-connect hoses simplify installation and removal
Pros: Space-saving design; Easy to install with quick-connect fittings; Affordable price point
Cons: Lower heat output not suitable for extreme cold
4. Maradyne UTV Heater Kit MCH3000: Premium Pick

The Maradyne MCH3000 is a premium option for those who demand the most heat. Based on our research, its 30,000 BTU output is the highest among the units we evaluated, making it suitable for extreme cold and larger cabs. The all-aluminum construction is built to last, and the three-speed fan with adjustable louvers gives you control over airflow. Owner reviews from northern climates are very positive.
The major downside is the cost, which is significantly higher than competitors. Additionally, installation is more complex due to the larger size and heavier weight. The unit may not fit in all UTVs without modification. We recommend this only for serious cold-weather riders with a generous budget and a UTV that can accommodate it. If you ride in moderate cold, you can save money with a less powerful heater.
- Powerful 30,000 BTU heater for extreme cold conditions
- All-aluminum core and housing for maximum durability
- Includes adjustable louvers for directional airflow
Pros: Highest heat output on this list; Very robust construction; Adjustable louvers help direct heat
Cons: Premium price may not fit all budgets
5. SuperATV UTV Heater Kit: Best for Polaris
The SuperATV UTV Heater Kit is tailored for Polaris RZR and General side by sides. Our research shows that it bolts directly to existing mounting points and uses a vehicle-specific harness, making installation much easier than universal kits. The 20,000 BTU output is solid, and the included defroster vents are a nice touch. Owner feedback is overwhelmingly positive from Polaris owners.
However, this heater is only compatible with Polaris models, so Can-Am, Kawasaki, and other brand owners need to look elsewhere. The plastic housing is not as durable as metal units, and some users report that the fan can be noisy. This is the best choice for Polaris owners who want a hassle-free install. If you have a different UTV brand, skip this one.
- Designed specifically for Polaris RZR and General models for easy fitment
- 20,000 BTU output with dual defroster vents
- Includes vehicle-specific wiring harness with plug-and-play connectors
Pros: Perfect fit for Polaris models; Includes defroster vents; Plug-and-play wiring simplifies installation
Cons: Limited to Polaris vehicles only
6. OTRATTW UTV Heater 12V: Budget Friendly
The OTRATTW heater is a budget-friendly option that we evaluated for value-conscious buyers. Based on owner feedback, it provides adequate heat for mild to moderate cold, and the universal brackets allow it to fit most side by sides. The 18,000 BTU output is respectable for the price, and the two-speed fan gives some control.
The main drawback is build quality: the plastic housing feels less robust and some owners report cracking in very cold temperatures. Also, the included wiring is basic and may require additional connectors. This heater is best for occasional use in moderate climates or for those on a tight budget. If you ride in harsh winters or need a long-lasting unit, invest in a higher-quality model.
- Affordable price makes it accessible for budget builds
- 18,000 BTU output suitable for moderate cold
- Universal mounting brackets fit most UTV models
Pros: Very low cost; Decent heat output for the price; Simple installation with basic tools
Cons: Plastic housing may crack in extreme cold
7. Kawasaki Genuine Accessories Heater Kit: OEM Fit

The Kawasaki Genuine Accessories Heater Kit is the official OEM solution for Teryx and Mule side by sides. Our research confirms that it integrates seamlessly with the vehicle’s electrical system and dashboard, offering a clean factory look. Installation is straightforward, and it comes with a Kawasaki warranty for peace of mind.
However, the 15,000 BTU output is relatively low, and it may not keep the cab warm in extreme cold. The price is also higher than many aftermarket heaters with better performance. This heater is best for Kawasaki owners who value perfect fit and ease of installation over raw heating power. If you need more heat, look at aftermarket options.
- Factory-designed fit for Kawasaki Teryx and Mule models
- 15,000 BTU output for basic heating needs
- Includes vehicle-specific wiring and mounting hardware
Pros: Perfect OEM fitment and finish; Easy installation with no modification needed; Backed by Kawasaki warranty
Cons: Low heat output compared to aftermarket options
Frequently Asked Questions
What size heater do I need for my side by side UTV?
The size depends on your cab volume and local climate. For most standard two-seat UTVs, 15,000 to 20,000 BTU is sufficient for moderate cold. For extreme cold below 0°F or larger four-seat cabs, consider a 25,000 to 30,000 BTU heater. Measure your cab space and check manufacturer recommendations.
Can I install a UTV heater myself?
Yes, many UTV heaters are designed for DIY installation. Most kits include mounting brackets, hoses, and wiring. Basic mechanical skills and tools like wrenches, screwdrivers, and a drill are usually required. Some models offer plug-and-play harnesses for easier installation. Always follow the included instructions and safety precautions.
Do I need a defroster for my UTV heater?
A defroster is highly recommended if you ride with a windshield. It helps prevent fogging and ice buildup, improving visibility. Some heater kits include defroster vents, while others require a separate defroster accessory. If you ride in wet or snowy conditions, prioritize a heater with built-in defrost.
Will a UTV heater drain my battery?
UTV heaters draw significant current, typically 10-20 amps. Running the heater for extended periods with the engine off can drain the battery. Most heaters are designed to be used while the engine is running to avoid battery depletion. Ensure your UTV’s alternator can handle the extra load. Some users upgrade to a higher-output alternator if needed.
Are UTV heaters safe to use?
Yes, when installed correctly. Look for heaters that meet safety standards like SAE or have thermal overload protection. Ensure the heater is securely mounted and wiring is properly fused. Never block the heater vents or use it in a closed space without ventilation. Follow the manufacturer’s installation guidelines to prevent fire or electrical hazards.
Our Verdict
After researching and comparing the top options, the MotoAlliance Firestorm 2.0 is our top pick for its excellent heat output, durable construction, and included defroster vents. For a more budget-friendly option that still performs well, the Kolpin 25-0140 is a solid runner up. Choose based on your UTV model, climate, and budget.
