Coal is the most widely used solid fuel for homes without gas and for boiler houses: it burns longer than firewood, gives more heat per kilogram and needs no drying before the season. One load of anthracite in a solid fuel boiler keeps the heat going for 8-12 hours, and a tonne of coal replaces roughly 2-2.5 tonnes of dry firewood in terms of heat.

Thermera sells two types of coal. Anthracite has the highest calorific value: about 7,000-8,000 kcal/kg. It burns with no smoke and almost no flame and leaves little ash. It needs a boiler with good draught and is slow to light, but it burns evenly and for a long time. The grades AO (АО, nut, 25-50 mm), AM (АМ, 13-25 mm) and AS (АС, 6-13 mm) differ only in lump size: for manual loading or for the auger of an automatic boiler. Long-flame coal DG (ДГ) is a bituminous coal with a high volatile matter content: it lights easily, burns with a long flame and suits any solid fuel boiler, stove or potbelly stove. Its calorific value is lower than that of anthracite, about 5,500-6,500 kcal/kg, so a tonne also costs less.

Packaging: 25 kg bags, big bags of about 1 tonne and bulk loads by truck. Bags are convenient for a house: they are easy to carry, stack in a shed and measure out per load. For boiler houses and purchases of several tonnes, bulk or big bags are better value, as the price per tonne is lower.

The price depends on the grade, fraction, packaging and volume: current prices per bag and per tonne are in the table below on this page. Delivery across Ukraine: from our warehouse with our own vehicles, and to other regions by carrier. Wholesale buyers and boiler houses get a supply contract, bank transfer payment with VAT and a test report for each batch showing ash content, moisture and calorific value.

How much coal you need per season

Enter the area, insulation and region to estimate heat demand, tonnes, bags and pallets. Add the price per bag to see your winter budget. The estimate is approximate: indoor temperature, wind and the boiler can shift it by 20-30 %.

How we calculate: heat demand = area × insulation rate (80 / 120 / 170 kWh per m² per season) × regional factor. Fuel = heat ÷ useful calorific value (including boiler efficiency): wood pellets 4.3, agro pellets 3.7, anthracite 5.6, DG 4.4 kWh/kg. Method and table in the article "How much fuel you need per season".

Bag → price per tonne

Sellers quote per bag, per pack or per tonne, but offers should only be compared per tonne. Enter the price and weight and we will work out the price per tonne and how many bags make a tonne. It also works the other way: enter a price per tonne to get the bag price.

Per tonne: 40,0 bags of 25 kg.

Formula: price per tonne = bag price ÷ bag weight × 1000.

Questions and answers

Anthracite or long-flame coal: which is better for a house?

It depends on the boiler. Anthracite gives more heat per kilogram and burns twice as long, but it needs good draught and is slow to light. It is the option for a boiler with a forced-draught fan or a tall chimney. Long-flame coal lights easily and burns in any boiler or stove, but burns out faster and gives more smoke. For a stove, potbelly stove or simple boiler without a fan, choose DG; for a modern boiler with automatic controls, choose anthracite.

How much coal do I need for the heating season?

As a rough guide, an insulated house of 100-150 m² needs 3-5 tonnes of anthracite or 4-6 tonnes of long-flame coal per season; without insulation, a third more. A kilogram of anthracite gives about 8 kWh of heat, long-flame coal 6.5-7 kWh. We can calculate more precisely based on floor area, insulation and region: give us a call.

How is the price calculated: per bag or per tonne?

Retail is per 25 kg bag (40 bags per tonne); big bags and bulk are priced per tonne. The table on this page shows the price in both units so you can compare packaging options, and the "Bag → price per tonne" converter turns any other supplier's price per bag into a price per tonne. Please check the minimum delivery quantity and the threshold for wholesale terms with our manager.

What do the grades AO, AM, AS and DG mean?

The first letter is the type of coal: A is anthracite, DG is long-flame gas coal. The second letter for anthracite is the lump size: K is large (50-100 mm), O is nut (25-50 mm), M is small (13-25 mm), S is pea (6-13 mm), Sh is fines (up to 6 mm). For manual loading, AO or AM is used; for automatic boilers with an auger, AS. All grades are explained in the guides.

Can I burn anthracite in a stove or fireplace?

We do not recommend it. Anthracite needs strong draught and a thick bed of embers; in a stove or fireplace it smoulders, catches poorly and can release carbon monoxide. Long-flame coal, firewood or fuel briquettes are suitable for stoves, fireplaces and potbelly stoves.

Where does the coal come from and what documents do you provide for a batch?

Each batch comes with a test report showing ash content, moisture, volatile matter and calorific value, and the origin of the coal (mine or country of import) is stated in the supplier's documents and on the delivery note. We do not write "Donetsk anthracite" without documents: since 2014 most anthracite in Ukraine has been imported, and an honest name on paper matters more than an attractive one on a website. We send the report on request before payment so you can compare the figures with other offers.

Coal in bags or in bulk: which is better value?

Per tonne, bulk is always cheaper because there are no packaging or pallet costs. But bags win if you have nowhere to tip a tonne under a roof, if you need to dose each load precisely, or if a bulk truck cannot get to your yard. A practical rule: up to 2 tonnes per season, bags delivered on a pallet; from 3 tonnes and with dry storage, bulk or big bags. You can compare both options in UAH per tonne with the converter on this page.

Can I order a single bag of coal as a trial?

Yes. We send a 25 kg trial bag of anthracite (AO, AM or AS) or long-flame DG by Nova Poshta to any city, with payment on receipt. Light it in your own boiler, look at the heat, smoke and ash, and order a tonne once you are sure the grade suits you.

Do I need to pay in advance for coal?

No. For retail orders, you pay the driver on receipt or by cash on delivery at Nova Poshta. Companies and boiler houses pay by bank transfer with VAT under a contract. Never transfer money to a "manager's" card before you receive the coal: that is how scammers from classified ads operate, not suppliers with proper documents.

How can I check that a bag holds 25 kg and a truck holds a tonne?

Weigh the bags in front of the driver; this is part of our delivery terms. A bag of graded coal holds 25 kg with a tolerance of about half a kilogram. Bulk loads and big bags are weighed at dispatch, the delivery note shows the actual weight, and if you wish you can check the truck on the nearest vehicle weighbridge. If anything is short, we will make up the weight or refund the difference.

How to choose coal: in brief

  1. Boiler first, then grade. A boiler with a forced-draught fan or a good chimney of 6 m or more: anthracite, which means more heat, less ash and less frequent loading. A simple stove, potbelly stove or boiler without a fan: long-flame coal, which lights from paper and kindling and does not go out on weak draught.
  2. Fraction to match the loading method. Manual loading: large lumps, AO 25-50 mm or DG 50-100 mm. An automatic boiler with auger or retort feed: a small fraction, AS 6-13 mm or AM 13-25 mm; the size the auger accepts is given in the boiler's data sheet.
  3. What you can see without a lab. Anthracite is black with a metallic sheen, heavy, rings when struck and hardly soils your hands. Long-flame coal is matte, layered, lighter and leaves a mark on your palm. Grey or brown lumps in a bag are rock: it does not burn and turns into ash.
  4. Fines in the bag. Small pieces and dust up to 10% of the weight are normal for graded coal; if a quarter of the bag is fines, the fraction does not match the grade.
  5. Compare the price of heat, not the price per tonne. Anthracite costs more per tonne but gives roughly 20-25% more heat than DG, so the cost per kilowatt-hour can be similar. Add delivery: for bulk it is charged separately.
  6. Documents. Ask for a test report for the batch: ash content, moisture, volatile matter, calorific value. We provide it together with the delivery note.
