Finovens work according to the countercurrent principle. The hot gases flow upwards and are then directed down to floor level before escaping through the chimney. The surrounding brick mass stores the heat from the fire and releases this heat in the form of pleasant radiant warmth for long after firing. Radiant heat feels like the pleasant warmth of the sun. It is a horizontally directed radiation which heats all the materials it encounters. This means a finoven in your home also heats the surrounding walls, floors and even the ceiling. The constant temperature and constant humidity created in this way ensures a stable and comfortable indoor climate.
Due to the high combustion temperature in the combustion room of approximately 1000 degrees Celsius, wood is decomposed totally. The ceramic glass window and the firing room remain free of soot, there is hardly any smoke and little ash is produced. Finovens are accumulating stoves that only need to be fired shortly. In almost all houses two hours of firing is sufficient for 24 hours of pleasant radiant heat. That means little work, low fuel consumption and low emissions in exchange for much pleasant warmth.
Regularly firing a heavy heater means it will stay warm constantly and therefore radiate pleasant heat for a very long time. Because of the larger storage capacity of a heavier heater, it needs be fired less often compared to a lighter model. The lightest finoven models weigh 750 kilograms, the heaviest 3000 kilograms. Finovens can be used as the main source of heating in a house, but can also easily be used alongside an existing heating system. It is also possible to place a heat exchanger in a finoven: you can read more about this at the additional information page. Burning wood in a finoven means you save on your energy costs.
Finovens burn wood, just like the other Vuurmeesters heaters. The wood is completely decomposed in a specially designed firing room where secondary combustion takes place because air enters through the sides and back of the firing room. The energy present in the wood is absorbed in the mass of the heater with an efficiency of between 75% and 85%. This percentage is in stark contrast to much lighter metal stoves with an efficiency of approximately 40% or an open fireplace with an efficiency of approximately 5%. Each finoven is delivered with extensive oral and written instructions to achieve an optimal efficiency.
In our finovens all varieties of untreated wood can be burned.
Willow, poplar, pine and pallet timber burns well in our stoves, without the frequently encountered problems in metal stoves such as soot and chimney fires.
A few kilograms of dry wood are enough for a whole day of pleasant warmth.
Wood is a renewable biofuel and also is carbon neutral.
Freshly cut wood must, depending on the type of wood and the humidity, dry for atleast one or two years.
Precut wood that is for sale often has a moisture content of 20-40%. It is therefore advisable to give this wood some time to dry aswell.
A moisture content in wood of approximately 15% or less is good for all types of heaters.
The heating value of wood varies by species and variety.
