WHAT KLOVER SEALED COMBUSTION IS
Sealed combustion is a feature of Klover appliances that combines two elements: the airtight sealing of the stove's openable parts and the centralized oxygen supply. According to the Klover description, together they make it possible to achieve extremely high performance in terms of efficiency and emissions, and to avoid energy waste.
On the klover.it website sealed combustion is listed among the features of 42 models: 28 pellet stoves, 7 pellet thermo-stoves, 6 pellet boilers and the DUAL 10s hybrid wood and pellet stove.
HOW THE AIRTIGHT SEALING OF THE OPENABLE PARTS WORKS
In Klover sealed combustion the first element is the sealing: the openable parts of the stove are airtight. The second element is the centralized oxygen supply to the combustion. Klover presents the two together, as a single system, and it is from this combination that the feature takes the name sealed combustion.
The regulation of the pellets and of the air that enter the fire, entrusted to Pellet Cruise Control, is described in the article on how a pellet stove works, from the burn pot to the room.

WHERE A SEALED COMBUSTION STOVE TAKES ITS AIR FROM
In a Klover appliance with sealed combustion the intake of combustion air, that is the air that feeds the flame, can also be taken from outside the home. In this way the combustion has a constant oxygen exchange.
Whether and how to take combustion air from outside is assessed by the technician who designs and carries out the installation, home by home, together with the route of the flue pipe.
WHY SEALED COMBUSTION MATTERS
According to the Klover description, sealed combustion matters for three reasons: efficiency, emissions and waste. The airtight sealing of the openable parts and the centralized oxygen supply make extremely high performance possible in terms of efficiency and emissions, and avoid energy waste.
The data sheets of the ECOMPACT pellet boilers sum up the same idea in one line: sealed combustion for safer, cleaner and more efficient operation.
KLOVER PELLET STOVES WITH SEALED COMBUSTION
The Klover pellet stoves with sealed combustion among their features are 28: AURA 80s, AURA 100s, AURA 120s, ASTRA 100s, ASTRA 100s GRES, ASTRA 100s GLASS, ASTRA 100s CARBON, CLASS 90s, DIVA SLIM AIR 100s, DIVA SLIM AIR 100s STONE, DIVA SLIM AIR 100s WOOD, KLIN 80s, KRONO 80s, KRONO 80s CARBON, KROS 80s, LADY 11s, MISS, OBLÒ 8s, OMEGA 120s, OMEGA 120s PLUS, ONE 8s, ONE 10s, SOFT 8s, SOFT 10s, SUPER 7s, SUPER 9s, VERTICAL 10s and VERTICAL 10s STONE.
The data sheets of these pellet stoves declare rated heat outputs from 6.4 kW (MISS) to 11.7 kW (AURA 120s, OMEGA 120s and OMEGA 120s PLUS) and efficiencies from 91.4% (MISS) to 95.4% (AURA 80s, CLASS 90s, KLIN 80s, KRONO 80s, KRONO 80s CARBON and KROS 80s).

THERMO-STOVES, BOILERS AND HYBRID STOVE WITH SEALED COMBUSTION
Among Klover pellet thermo-stoves sealed combustion is found on THERMOAURA 120s, THERMOSUPER 120s, STYLE 15, STYLE 19, STYLE 19 PLUS, STYLE 21 and STYLE 21 PLUS. The data sheets of these 7 pellet thermo-stoves declare efficiencies from 94% to 96%.
Among pellet boilers sealed combustion is found on 6 models: ECOMPACT 20, ECOMPACT 23, ECOMPACT 26, ECOMPACT 29, ECOMPACT 32 and ECOMPACT 35. The data sheets declare rated heat outputs from 19.1 kW to 32.4 kW and efficiencies from 92.5% to 92.8%.
The DUAL 10s, a hybrid wood and pellet stove, also has sealed combustion among its features: the data sheet declares an efficiency of 92% with pellets and 86% with wood.
In short, Klover sealed combustion combines the airtight sealing of the openable parts and the centralized oxygen supply, allows combustion air to be taken also from outside, and is present on 42 models.
