Sauna Stones (Tier 2 and Tier 3 packages)
Every "Heater + Stones" and "Heater + Stones + Chimney" package ships with the correct quantity of Harvia AC3020 sauna stones, olivine diabase, 10–15 cm size grade, 20 kg (44 lb) per box. Wood-burning stoves use the larger 10–15 cm AC3020 grade because the bigger stones pack better in the open top-loaded stone bed and hold heat longer through the natural rise-and-fall thermal cycle of a wood fire.
Insulated Chimney Kit (Tier 3 packages)
The "Heater + Stones + Chimney" tiers bundle the Harvia WHP1500 Pre-Packaged Chimney Kit, the factory insulated chimney assembly Harvia ships for standard residential sauna installations. The kit includes:
- 1500 mm insulated chimney pipe
- 1 m smoke pipe
- Rain cap
- Rain boot
- Chimney clamp
- Lead-through insulation and protector
- Lead-through cover
Choose your finish: every heater in this family is offered with either the Stainless Steel (WHP1500) kit or the Black (WHP1500M) kit at Tier 3, the chimney finish is your decision, not auto-matched to the heater. Most customers pick the chimney that visually complements the room they're installing into: black for traditional sauna interiors, stainless for modern / commercial finishes.
Important: The WHP1500 kit covers a standard residential chimney run. If your installation deviates from the standard 1500 mm vertical configuration, longer chimney run, tilted offset, attic insulation penetration, multi-storey installations, or commercial roof tie-ins, additional chimney components (WHP1000 / WHP500 extensions, WHP270SP smoke damper, WHP-AS tilted accessory kit, etc.) will be required. Contact Finnish Sauna Builders before ordering for a chimney layout consultation.
Installation Requirements
Wood-burning sauna heaters require a non-combustible floor surface, proper clearance to combustibles per the installation manual, a code-compliant insulated chimney run penetrating the roof or wall, and adequate combustion-air supply. Always defer to the included Harvia installation manual and your local AHJ for final clearance, chimney, and venting requirements. Most jurisdictions require a permit and inspection on wood-burning sauna heater installations.
