Before you buy: what to know
Based on the manufacturer's specs, manuals and our research.
- The Linear 22 GreenFlame is 15.7 kW with a large panoramic glass door and no water tank. If you want hot water, the ES version adds a 20 liter tank.
- Harvia rates GreenFlame at 20% lower particulates and 70% lower carbon monoxide. It holds up to 88 lb of stones, included, and the internal parts are replaceable.
- 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.
- Returns are accepted within 30 days with a 25% restocking fee on unused, unopened items. Work out your room volume first, so the output you order is the right one.
