The Jøtul F 620 B HT Wood Burning Stove is a tall cast iron stove designed to combine substantial heating performance, extended heat retention and an impressive three-sided view of the fire. Producing a manufacturer-stated nominal heat output of 8.7kW, it is particularly well suited to larger rooms and open-plan living spaces where strong heat output and a commanding contemporary design are required.
The defining feature of the Jøtul F 620 B HT is its high-top construction with integrated heat-storing stones. These stones absorb surplus heat while the stove is burning and release it gradually after the fire has reduced. According to Jøtul, this can provide up to 12 additional hours of heat after the final log has been added, helping maintain a more comfortable room temperature for longer.
Beneath the combustion chamber is a practical open log storage compartment, keeping firewood close to hand while raising the stove to a comfortable viewing height. Combined with its tall upper section, this gives the appliance a substantial architectural presence that works particularly well in larger contemporary interiors.
The fire can be viewed through three large glass panels, providing a panoramic flame picture from the front and both sides. A specialist coating on the glass works alongside the integrated airwash system to help reduce soot deposits and keep the view clearer during use. Light-coloured solid cast iron inner plates further brighten the combustion chamber, helping the flames remain visually prominent.
User-friendly air controls make the stove easier to light and allow the burn rate and flame intensity to be adjusted as required. An internal log retainer helps keep burning fuel safely positioned within the chamber, while the secure snap-lock door supports convenient and reliable everyday operation.
Constructed from durable cast iron, the Jøtul F 620 B HT offers an efficiency of 77%, carries an A energy rating, and is compatible with an external combustion air supply. Its combination of heat-storage technology, substantial output and three-sided glazing makes it one of the most practical and visually impressive models within the Jøtul F 620 range.

Expert Insight
The heat-storage top is the most important difference between this model and the other stoves in the F 620 range. Rather than allowing all the generated heat to leave the appliance immediately, the storage stones retain part of it and release it gradually, helping the room remain warmer after the fire has died down.
Suitability
The Jøtul F 620 B HT Wood Burning Stove is best suited to larger living rooms, open-plan interiors, rural properties, and homes wanting a tall statement stove with extended heat retention and a panoramic flame view.
