Fuel briquettes: RUF, Pini-Kay, Nestro and peat briquettes with delivery

For a fireplace or stove: Pini-Kay. They are the densest, burn longer and give even heat without sparks. For a boiler: RUF or Nestro. They burn a little faster but are cheaper per tonne and easier to stack. In calorific value all three are close; the difference is mainly in density and burn time. A detailed comparison is in our buyer's guide.

Briquettes have a moisture content of up to 10% versus 20-25% for firewood after a year of drying, so you get twice as much heat per kilogram, with less soot and smoke. A tonne of briquettes takes up about 1.5 m³ instead of the 5-6 m³ of firewood needed for the same amount of heat, and there is no chopping or extra drying. The downside: briquettes are sensitive to damp and burn with a smaller flame.

An insulated house of 100-150 m² needs 4-6 tonnes of wood briquettes or 6-8 tonnes of peat briquettes per season; without insulation, about a third more. A kilogram of wood briquettes gives about 4.5-5 kWh of heat, peat briquettes 3.5-4.5 kWh. Call us and we will work out a more accurate figure for your floor area and boiler.

Yes, briquettes are designed precisely for manual loading: any solid fuel boiler, stove, fireplace, potbelly stove or sauna stove. Briquettes are not used in a pellet boiler with an auger feed; that is what pellets are for. The only rule is not to pack the firebox full: briquettes expand as they burn.

Dry and off the ground: in packs on a pallet under a canopy or indoors. Wood briquettes absorb moisture and fall apart, and peat briquettes go soggy. Shrink-wrapped packs protect against splashes, but not against rain. Stored this way, briquettes keep for several seasons without any loss.

Most often it is because the ash door vent was left open. Briquettes are pressed from dry sawdust, and with full air supply they burn like a newspaper: fast and with a big flame. A burn time of 2-4 hours is achieved with the ash door vent and damper partly closed, when the briquette smoulders and releases heat evenly. The second reason is stacking briquettes tightly in a pile: there should be an air gap between them. And the third is a briquette made from damp or loose raw material: it is light, crumbly and burns like wood shavings. Check this with a trial pack before buying a pallet.

Per tonne, briquettes cost more than firewood, but the right comparison is per kilowatt-hour of heat: a tonne of dry wood briquettes replaces 3-4 stacked cubic metres of firewood. Since market firewood roughly doubled in price in 2025-2026, the difference in cost per unit of heat has almost disappeared, and briquettes win on convenience: no chopping, no year of drying and no need for space to store 6 cubic metres. State firewood under the eFirewood program (ДроваЄ) remains cheaper than briquettes, if you are eligible for it and have somewhere to dry it. A comparison per kilowatt-hour is in the article "Calorific value of different fuels".

Yes. We send a trial pack of RUF, Pini-Kay or Nestro (10 kg) or a bag of peat briquettes (25 kg) by Nova Poshta to any city, cash on delivery. You can combine two types in one shipment and compare them in the same stove.

We do not take prepayment: you pay the driver on delivery or cash on delivery via Nova Poshta, and businesses pay by bank transfer with VAT under a contract. A pallet holds 96 packs of 10 kg, i.e. about 960 kg; you can weigh any pack in front of the driver and count the packs. If the weight is short or packs are missing, we will make up the difference or refund it.

There are 100 packs of 10 kg in a tonne, so pack price × 100 = price per tonne in packs; a pallet is 96 packs, about 960 kg. A pack at 120 UAH works out at 12,000 UAH per tonne. Compare offers exactly this way, because some sellers quote per pack and others per tonne or per pallet. The "Bag → price per tonne" converter on this page works both ways.
