Key specs for this chimney kit
Material: Stainless steel
This material resists rust and heat damage better than painted metals. You get a durable chimney that lasts through many heating cycles. It stays clean with minimal effort. If you live near the coast, this resistance to salt air is a key benefit. It also looks sharp without needing paint.
Mounting: Flat roof
This kit is built specifically for flat roofs, not sloped ones. It includes the correct flanges and seals for that surface. If you have a flat roof, this fits your structure without extra adapters. Sloped roofs need different parts. Always match the mounting type to your actual roof shape before buying.
Design: Barrel
A barrel shape creates a smooth, rounded exterior. This style sheds rain and snow effectively. It also provides a classic sauna look for your home. The curved surface helps airflow around the pipe. You get a sturdy structure that blends well with traditional sauna aesthetics on your flat roof.
Width: 24 inches
The width measures 24 inches across. This size fits standard chimney openings for most home saunas. It provides enough surface area for proper heat dissipation. Smaller widths might restrict airflow. Larger ones take more space. This 24-inch width balances performance with a manageable footprint for your installation area.
Height: 24 inches
The height is 24 inches tall. This length helps establish a good draft for your sauna stove. A taller chimney pulls smoke up efficiently. It keeps the exterior surface cooler near the roof. If your stove needs more draft, this height is a solid starting point for flat roof setups.
Length: 24 inches
The length is 24 inches deep. This dimension ensures the pipe extends properly through your roof structure. It provides enough space for insulation and seals. This depth helps prevent leaks around the penetration point. You get a secure fit that protects your roof from water damage while venting the sauna safely.
Design and build details
According to the listing, the Harvia WHP1000500-PKG is built from stainless steel. This material choice supports its use in both indoor and outdoor settings. Stainless steel handles temperature changes well, which prevents movement in the chimney structure. The barrel design gives it a distinct shape that fits flat roof requirements. You do not need to worry about paint peeling or rust forming quickly, as the metal is inherently resistant to those issues. This makes it a low-maintenance option for your sauna setup.
The kit includes several components to ensure a complete installation. You get the WHP1000500 chimney, a rain cap, and a symmetrical rain flange. The package also provides lead-through insulation, a protector, a lead-through flange, a smoke pipe, and a clamp. Having all these parts in one box simplifies the assembly process. You can install it yourself without sourcing extra pieces. The design is engineered in Finland, which suggests a focus on precision and durability in its construction.
Dimensions are listed as 24 inches in width, height, and length. This cubic footprint helps it fit standard flat roof openings. The compact size means it does not take up excessive space on your roof. The stainless finish remains consistent across all parts. This uniform look is practical for maintaining a clean appearance over time. The symmetrical flange ensures a secure seal regardless of wind direction. This feature helps keep rain out of your sauna, protecting your interior from moisture damage during heavy storms.
