Harvia is one of the best-known Finnish heater makers, founded in 1950, with a wide range of electric heaters and wood-burning stoves. HUUM is an Estonian brand known for open stone heaters, where the stones themselves give the heater its shape. Both make good heaters; what matters is which models are rated for your room.
Brand-neutral: models are listed by size, not by commission. How this works
Room ranges are the makers' own ratings. Models rated for the room you entered are marked.
