What is the best wood boiler for Thessaloniki?
AXINAR wood boiler, made in Thessaloniki, Greece
For a 200-300 m² home in Thessaloniki we recommend PESKON PSK30 (30 kW) at €1,625 incl. VAT. For medium buildings up to 900 m² there are BM30/BM60/BM90 models, and for industrial applications up to 2,500 m² the premium BM_E90/BM_E150/BM_E250 with Lambda sensor and advanced software. AXINAR manufacturing in Oraiokastro Industrial Area, EN 303-5 certified, 5-year body warranty, 48h on-site service.
The best wood boiler for Thessaloniki is one that is locally manufactured, accepts Greek-sourced firewood, has direct on-site service, and matches your home’s square footage.
AXINAR manufactures 8 wood boiler models across 3 series, from the economic PESKON for small homes to the industrial BM_E with Lambda sensor and advanced software. Thessaloniki’s climate requires proper sizing and adequate firebox size to accept large firewood pieces (30-50 cm).
We typically calculate 0.10-0.12 kW per m² for homes with moderate insulation. The wood boiler requires firewood loading every 4-8 hours depending on firebox size and heating demand.

How many kW for your square meters?
For Thessaloniki’s climate (Zone C, winter with days below 0°C), the basic sizing rule for wood boilers is:
0.10-0.12 kW per m² for moderately insulated homes (slightly higher than pellet because wood has lower combustion stability), 0.08 kW/m² for good insulation, 0.14 kW/m² for old buildings without insulation.
Add 15-20% margin for the coldest days and for DHW combination. Other factors: ceiling height, orientation, glazing.
| Square meters | Power | Model |
|---|---|---|
| 150-250 m² | 15-30 kW | PSK30 / BM30 |
| 250-400 m² | 25-45 kW | PSK30 / BM30 |
| 400-600 m² | 40-70 kW | PSK60 / BM60 |
| 600-800 m² | 60-90 kW | BM60 / BM90 |
| 800-1200 m² | 80-135 kW | BM90 / BM_E90 |
| 1200-1800 m² | 135-200 kW | BM_E150 |
| 1800-2500 m² | 180-280 kW | BM_E250 |

Exoikonomo 2026 and Thessaloniki
The “Exoikonomo 2026” program subsidizes the replacement of old oil boilers with biomass boilers (pellet or wood). Thessaloniki belongs to Climate Zone C with 50-65% subsidy depending on income. Wood boiler is treated as equivalent to pellet for subsidy purposes.
Wood vs pellet, oil, gas
Indicative prices for a 200 m² home in Thessaloniki with moderate insulation, 6 months of heating usage:
| Criterion | Wood (AXINAR BM/PESKON) | Pellet (AXINAR PELIT) | Oil | Natural gas |
|---|---|---|---|---|
| Purchase cost | €1,625-2,852 | €1,711-2,703 | €1,200-1,800 | €2,500-3,500 |
| Annual fuel cost | €900-1,300 | €1,300-1,800 | €2,800-3,500 | €1,900-2,500 |
| Payback period | 2-3 years | 3-4 years | n/a | 6-8 years |
| Manual fuel loading | Yes (every 4-8 hours) | No (automatic) | No | No |
| Storage space | Large (5-10 m³) | Small (silo/sack) | Tank | None needed |
| Availability in Thessaloniki | Excellent (firewood) | Excellent | Excellent | Only in grid |
| Exoikonomo 2026 subsidy | 50-65% (Zone C) | 50-65% (Zone C) | No | No |
| Renewable | Yes (biomass) | Yes (biomass) | No | No |
Wood boiler wins on operational cost and faster payback, but requires manual loading and storage space. Pellet is more comfortable (automatic) but with slightly higher operational cost.
Glossary
- Firewood (oak, beech)
- Dried wood logs 6-15 cm diameter and 33-50 cm length depending on model. Calorific value 4.0-4.3 kWh/kg when dry (moisture <20%). Sold at firewood shops and agricultural stores in Thessaloniki.
- Lambda sensor
- Oxygen sensor in the flue gases that measures O₂ content. Allows the BM_E advanced software to automatically adjust air supply for optimal combustion. Increases efficiency by 5-8%.
- Pyrolysis
- Thermochemical process where wood decomposes into combustible gases at high temperature (600-900°C). Modern AXINAR wood boilers burn these gases in a second chamber, increasing efficiency.
- EN 303-5
- European standard for biomass boilers. Requires efficiency >89% and low CO/CO₂/dust emissions. Mandatory certification for Greek subsidies.
- Climate Zone C
- Greek climate zone for energy design. Includes Thessaloniki, Central Macedonia, Epirus. Design temperature -3°C.
- Integrated exchanger
- PESKON technology where the heat exchanger is located within the boiler itself. Simplifies installation and reduces cost.
- Dry wood (moisture <20%)
- Firewood that has dried at least 1-2 years. Critical for maximum boiler efficiency, reduced ash, and cleaner combustion. Wet wood causes tar buildup and damage.
- Flue system
- Combustion gas exhaust pipeline. Wood boiler requires flue at least 8m tall with strong draft. Inspection by certified chimney sweep before installation.
