Wood Fired Sauna Heater

Sale Price: $1,250.00 Original Price: $1,500.00

Engineered for authentic sauna heat, long steam sessions, and years of hard use.

The Hardy sauna heater is built around a heavy-duty replaceable firebox system designed to deliver serious thermal performance while increasing flexibility.

At the center of the system is a removable 1/4" steel firebox that nests directly into the outer frame and rock cage assembly. If the firebox wears out it can be replaced by simply lifting it out — extending the service without replacing the full structure.

1/8” steel outer rock cage creates a rigid structure capable of supporting large quantities of sauna stone for deep, long-lasting steam sessions.

The heater also features airtight combustion control, internal heat-management baffles engineered and tested to optimize heat transfer, and a removable ash pan for fast clean out.

Designed to heat up to 300 lbs of sauna stone in as little as 40 minutes, the Hardy heater prioritizes:

  • thermal mass

  • steam quality

  • durability

  • real-world usability
