All of our stoves are exceptional, but the NUT stove is even more exceptional; both in terms of esthetics and a technical design that features a grateless firebox and tertiary combustion.

The NUT evokes visions of chateaus, where you may have seen similar stoves. The price of an antique chateau stove would of course be several times that of our popular NUT. For a price comparable to other tile stoves you can grace the interior of your home while getting modern and efficient heating. The grateless E2 stove insert with tertiary combustion is mounted on a low tile base, while the top half of the stove consists of a tall cylindrical tower with vent tiles. The total height of the stove is 200 cm.

Similar to other types of stoves, the round tower above the firebox can be filled with fire brick. This material partially reduces the immediate output of the stove (which can be regulated between a range of 3 – 11 kW by adjusting the air damper and quantity of fuel), but can extend the radiation of pleasant, healthy heat by several hours, without dust or particulate matter.

NUT stoves are well served by single color designs with smooth glossy white or red tiles. But as with all our other stoves you can choose any shade of tile color you like to match the interior of your home or heated space (stoves can be a great decoration and source of heat for rustic restaurants, wine bars, hotels, guest houses, event halls, etc.).

Like the ATÉNA, the NUT is equipped with an E2 stove insert with tertiary combustion. And what does all this mean?

Grateless firebox

It is mostly out of habit that many people prefer a firebox with grate, yet this manner of combustion also has several disadvantages. Air that is not pre-heated enters the firebox through the grate and lowers the combustion temperature. This lowers the efficiency of the heater. A grate firebox has an ashpan, which must frequently be emptied. If the ashpan is not emptied regularly, it will fill up and limit the flow of air through the grate. The grate will stop being cooled by air flowing through it and may become deformed or twisted. And unlike fossil fuels, wood does not require a grate to burn. This grateless firebox has been developed based on new knowledge about wood combustion. Grateless fireboxes better heat wood gases and increase the efficiency of the heater. This is achieved by removing the grill from the firebox. The bottom is much deeper, you do not need to remove ash as frequently (once every 3–4 weeks, even longer). Also, even the smallest coals are burned which otherwise would have fallen through the grate into the ashpan. This dramatically decreases the amount of ash in the stove. Pre-heated air for combustion is supplied from the interior or exterior through the door. Air is designed to flow around the glass in the door to prevent the buildup of tar and ash on the glass. Flowing air also cools the ceramic glass to prevent it from becoming damaged. The manner of starting a fire is slightly different than for stoves with grates. Most customers are used to starting fires from below, but in general and particularly for grateless fireboxes, it is more effective to start a fire from above. Larger pieces of wood are placed at the bottom, then some firestarter sticks, smaller pieces of wood or wood chips. When the firestarter catches, it will get enough air and won’t make a lot of smoke. The smaller pieces of wood or wood chips will catch from the firestarter and then fall onto the larger pieces of wood, lighting them as well. This manner of heating is very effective.

Tertiary combustion

This technology is based on burning the residual combustible gases created when burning fuel. This makes use of the residual gases, which otherwise would just go up the flue unused. Metal cascades with holes (nozzles) are placed over the fire, which brings additional air to the top of combustion chamber. The air is guided through a channel along the combustion chamber, where it is preheated to a high temperature. The residual flammable gases that accumulate at the top of the fireplace are again oxygenated with warm air and flash with a blazing flame. They transmit another heat and minimum smoke is fed into the chimney. This makes for higher quality, more efficient combustion. Thanks to tertiary heating you save. Increasing stove efficiency decreases total fuel consumption and also prolongs burning time. At the same time, the flue gases vented up the chimney are cleaner, which means less soot in your chimney and less chimney maintenance.

Standard NUT stoves are not equipped with water heat exchange, but custom models can be constructed with a classic E1 stove liner (with grill and output of 5–11 kW) and E1 VO water heat exchanger that absorbs up to 8 kW of energy out of a total maximum output of 11 kW. The flue pipe typically runs from the back but can also run from the top. As with other stoves, the recommended fuel is dry hardwood or quality wood briquettes. Wood should not have a moisture content greater than 20%, which corresponds to roughly 2 years of storage. For proper burning and heating it is important to connect to a suitable and properly sized chimney with a flue pipe at least 150 mm in diameter with effective height of at least 5 meters. Naturally, when installing the stove it is necessary to comply with fire protection and safety measures, including placement of the stove at a distance of at least 20 cm from walls (and twice that distance from combustible materials), placing the stove on a fireproof base (extending at least 300 mm in front of the door and ashpan and 100 mm in other directions), etc.

Professional installation and connection can be arranged upon sale, but are not included in the price of the stove.
