Stiglen 129 Masonry Heater Core, 12 kW

Stiglen 129 burns from cold to working temperature in about 20 minutes and holds it on two refills an evening.

The door seals on a braided rope gasket in a machined channel. That channel is the part that decides whether a stove still shuts tight after a decade of slamming.

Secondary and tertiary air are pre-heated before they reach the fire, which is what burns the smoke instead of sending it up the flue. Firebricks and baffles are wear parts — they are listed as spares and take ten minutes to change.

Care

Sweep the flue once a season and check the door rope every autumn: a stove that has started smoking into the room is almost always a seal, not a chimney.
