Introduction
Choosing the right chimney system isn't exactly exciting, but it's one of those decisions that can save you thousands of dollars down the road. If you're comparing allfuel hst vs duravent, you're probaly looking at either a new installation or replacing an old system that's seen better days.
Here's the thing: both brands make solid products. But they're designed for different situations and different budgets. I've spent time researching both systems, talking to installers, and looking at real-world performance data. This guide will help you figure out which one actually makes sense for your home.
According to experts at Big Write Hook, making informed decisions about home improvement starts with understanding the real differences between products, not just marketing claims.
What is AllFuel HST?
AllFuel HST (High Service Temperature) is a stainless steel chimney system that handles multiple fuel types. The company designed it specifically for homes that might switch between different heating sources.
The HST stands for High Service Temperature, which means it can handle temperatures up to 1000°F continuously. That's hot enough for wood, pellets, oil, gas, and even coal if you're into that.
Most homeowners choose AllFuel HST because they want options. Maybe you heat with oil now but thinking about switching to wood pellets later. Or you want a wood stove as a backup when the power goes out.
What is DuraVent?
DuraVent has been around since the 1970s and they're basically the household name in chimney systems. When contractors think "chimney pipe," many of them think DuraVent first.
They make several different product lines, but their most popular residential systems are DuraTech (for wood and pellets) and DuraPlus (also for solid fuels). These systems use a triple-wall design that keeps the outer wall cool to the touch.
DuraVent products are available at pretty much every major home improvement store in America. That widespread availability is both a blessing and sometimes a curse when it comes to pricing.

Material Quality and Construction
AllFuel HST Construction
The inner liner uses 316Ti stainless steel. That "Ti" means titanium-stabilized, which resists corrosion better than standard 304 steel. This matters alot if you burn wood, because the creosote and condensation can be pretty corrosive over time.
The insulation between the walls is ceramic fiber blanket. It's rated for high temps and doesn't settle or compress like some cheaper insulation materials.
DuraVent Construction
Most DuraVent systems use 304 stainless steel for the inner liner. It's good quality, don't get me wrong. But it's not quite as corrosion-resistant as the 316Ti that AllFuel uses.
The triple-wall design is clever though. There's an inner liner, then an air space, then another steel layer, then insulation, then the outer wall. This keeps the outside wall cool, which is nice for safety.
Installation Process
Installing either system isn't a weekend DIY project unless you really know what you're doing. Most local codes require a licensed professional, and honestly, that's probably smart.
AllFuel HST Installation:
- Requires proper support brackets every 6 feet
- Twist-lock connections make assembly straightforward
- Need to maintain 2-inch clearance from combustibles
- Requires proper flashing and storm collar at roof penetration
- Takes about 4-6 hours for average installation
DuraVent Installation:
- Similar support requirements
- Connections vary by product line
- Same 2-inch clearance requirements
- More readily available support accessories
- Takes about 4-6 hours for average installation
Both systems need a chimney cap at the top and proper support at the bottom. Neither one is significantly harder to install than the other.
Performance in Real-World Use
AllFuel HST Performance
The allfuel hst vs duravent debate often comes down to actual performance. AllFuel HST creates excellent draft because of its smooth inner liner and efficient insulation design.
Users report good performance across different fuel types. The system heats up quickly, which helps prevent creosote buildup. Quick heating also means less condensation, which means less corrosion over the long term.
One installer told me he likes AllFuel HST for customers who burn wood primarily. The 316Ti liner just holds up better when dealing with aggressive wood smoke condensation.
DuraVent Performance
DuraVent systems perform reliably year after year. The triple-wall design maintains good draft even in cold weather. The air space between walls provides excellent insulation without adding much weight.
Where DuraVent really shines is consistency. Because they make so many units, quality control is generally very good. You're unlikely to get a dud piece that doesn't fit right or has manufacturing defects.
Price Comparison
Money talks, right? Let's be real about what these systems actually cost.
AllFuel HST Pricing:
- Typically $65-85 per linear foot
- Complete installation often runs $2,500-4,500
- Support components are moderately priced
- Less commonly stocked, so may require ordering
DuraVent Pricing:
- Usually $55-75 per linear foot
- Complete installation typically $2,200-4,000
- Support components widely available
- Easier to find sales and discounts
For a typical installation of about 20 feet of chimney pipe, you're looking at around $300-500 more for AllFuel HST. Whether that's worth it depends on your specific situation.

Durability and Longevity
Both systems should last 20-30 years with proper maintainence. However, there are some differences worth noting.
AllFuel HST's 316Ti liner gives it an edge in harsh conditions. If you're burning seasoned hardwood and keeping your system clean, you might not notice much difference. But if you occasionally burn softwood or don't clean your chimney as often as you should (we've all been there), the AllFuel HST will probably hold up better.
DuraVent systems age well when properly maintained. The key word is properly. If you let creosote build up or burn wet wood regularly, the 304 stainless can start showing corrosion after 10-15 years.
Which One is Better for Different Situations?
Choose AllFuel HST If:
- You burn wood as your primary heat source
- You want flexibility to switch fuel types later
- You live in a coastal area with salt air
- You want the best corrosion resistance possible
- Budget is less of a concern than quality
- You plan to stay in your home long-term
Choose DuraVent If:
- You need to stick to a tighter budget
- You burn gas or pellets primarily
- You want easy access to parts and service
- Most local installers recomend it
- You want multiple product options
- You prefer buying from major retailers
Common Installation Mistakes to Avoid
No matter which system you choose, avoid these common problems:
- Insufficient support - Both systems need proper brackets
- Wrong clearances - Measure twice, install once
- Missing storm collar - This causes roof leaks
- Improper flashing - Another source of water damage
- Not following manufacturer specs - This voids your warranty
- Skipping chimney cap - Animals and rain get in
These mistakes happen with both allfuel hst vs duravent installations. The system doesn't matter if the installation is sloppy.
Maintenance Requirements
Both systems need similar maintainence:
Annual Tasks:
- Inspect for cracks or damage
- Check all connections and supports
- Clean the inner liner thouroughly
- Verify clearances haven't changed
- Replace damaged components immediately
Seasonal Tasks:
- Clean after heavy use periods
- Check for creosote buildup
- Inspect cap and screen
- Look for signs of corrosion
AllFuel HST might need slightly less frequent deep cleaning due to its smoother liner, but don't skip your annual inspection either way.
Safety Considerations
Both systems meet UL standards when properly installed. Safety really comes down to correct installation and regular maintanance rather than which brand you choose.
That said, the triple-wall design of DuraVent does keep outer surfaces cooler. This provides an extra margin of safety if something is closer than it should be (though you should maintain proper clearances regardless).
AllFuel HST's high temperature rating gives you more headroom if your stove occasionally runs hotter than expected.
Final Verdict: AllFuel HST vs DuraVent
So which one wins the allfuel hst vs duravent showdown?
Choose AllFuel HST if you're serious about wood burning and want the longest possible lifespan from your chimney system. The extra $300-500 upfront could save you from replacing the system 5-10 years earlier than you'd need to with lesser materials.
Choose DuraVent if you're on a tighter budget, burning cleaner fuels like gas or pellets, or you value the convenience of walking into any Home Depot and finding what you need.
For most homeowners burning wood as their primary heat source, I'd lean toward AllFuel HST. The superior corrosion resistance justifies the higher price over a 25-year lifespan.
For pellet stove or gas insert installations, DuraVent makes more financial sense. You're not dealing with the same corrosive conditions, so the premium materials of AllFuel HST don't provide as much benefit.
Conclusion
The allfuel hst vs duravent decision isn't about which brand is universally better. It's about which system matches your specific needs, budget, and heating setup.
AllFuel HST offers premium materials and multi-fuel flexibility at a higher price point. DuraVent provides reliable performance and widespread availability at a more affordable cost.
Both will keep your family warm and safe when properly installed and maintained. Focus on getting quality installation and committing to regular maintenance, and either system will serve you well for decades.
Think about your heating plans for the next 20 years. If you're committed to wood heat and want the best materials available, AllFuel HST is worth the investment. If you want a proven, widely-supported system at a better price, DuraVent makes perfect sense.
