Description
This Harvia Pro 20 package is a complete wood-fired sauna heating setup. It includes the 24 kW Pro 20 stove, a 22 liter stainless steel water heater, a CE-marked chimney kit with a 39.4 in extension, protective floor bedding, a three-sided protective sheath, and 88 lb of stones. It heats rooms from 283 to 706 cubic feet.
Installation
The protective bedding shields the floor from heat and embers. The three-sided sheath reduces the required safety distance to combustible materials, giving you more freedom in where the stove goes. The 39.4 in chimney extension helps with taller ceilings.
Water heater
The 22 liter stainless steel water heater gives you hot water for washing or for throwing on the stones.
Package with or without the water heater
The Pro 20 package with chimney kit has the same stove without the water heater.

Before you buy: what to know
Based on the manufacturer's specs, manuals and our research.
- This is a complete wood-fired setup: the 24 kW Pro 20 stove, a 22 liter stainless water heater, a chimney kit with 39.4 in extension, bedding, a three-sided sheath and 88 lb of stones.
- It heats rooms from 283 to 706 cu ft. The chimney extension helps with taller ceilings, and the sheath reduces the safety distance to combustible materials.
- Choose black or silver. If you do not need the water heater, the Pro 20 package with chimney kit is $900 less.
- Clearances to walls, ceiling and benches come from the installation manual, and a wood stove also needs a proper chimney run. Check local code and your insurer before you build around it.
- It usually ships within 1 to 3 business days and arrives in about 5 to 10 business days, so it can be on site before your build is finished.
