Convert your existing oil boiler to pellet by replacing only the burner. AXINAR manufacturing in Oraiokastro Industrial Area, 7 APOPLIM and TSOVEA models from 20-150 kW, 48h on-site service in Thessaloniki and Central Macedonia.
Instead of replacing the whole boiler (cost €1,700-5,700 + installation), you replace only the burner. Your existing oil boiler stays and the AXINAR pellet burner is mounted on it. Cost €1,184-3,621 for 20-150 kW. Annual savings 60-70% vs oil. Payback in 1.5-2.5 years.
Burner replacement is the most economical and fastest transition from oil to pellet. No need to change the boiler, piping, or radiators. The certified installer removes the old oil burner, screws the AXINAR pellet burner onto the same flange, tunes the combustion, and you’re ready.
The entire process takes 1-2 working days. Home heating is not interrupted for more than one day.
In Thessaloniki, with typical annual oil cost of €2,500-3,200 for a 150 m² home, the transition to pellet reduces annual cost to €800-1,200. Burner investment payback in 1.5-2.5 years.
Production at our Oraiokastro Industrial Area factory. Greek design for Greek fuels (ENplus A1/A2 pellet).
No boiler change, no piping change. Only the burner is screwed onto the position of the old oil burner.
All models feature automatic firebox cleaning with auger. Minimal maintenance, just empty ash bin every 1-2 months.
Modulating power output 30-100% depending on heating demand. Maximum efficiency, minimum consumption.

Burner sizing follows the same logic as boiler sizing, but with one specificity: the burner must match the maximum power your existing boiler can handle.
General rule for Thessaloniki (Zone C): 0.10 kW per m² for moderate insulation. Additionally, the burner should be ≤ 90% of the boiler’s nominal power (for margin).
If your existing oil boiler is 30 kW, the APOPLIM AP30 (30 kW) fits perfectly. If it’s larger (e.g., 45 kW), you can go with APOPLIM AP45. For commercial applications (apartments, hotels), TSOVEA covers 75-150 kW.
| Square meters | Power | Model |
|---|---|---|
| 150-200 m² | 15-20 kW | APOPLIM AP20 |
| 200-300 m² | 20-30 kW | APOPLIM AP30 |
| 300-450 m² | 30-45 kW | APOPLIM AP45 |

Pellet burner is the most economical pathway to pellet when you already have a functional oil boiler. If your boiler is >15 years old or in poor condition, a new pellet boiler (PELIT) may be a better long-term choice.
If your existing boiler is >15 years old or in poor condition, a new AXINAR PELIT pellet boiler may be a better long-term choice.

If you prefer firewood over pellet (lower fuel cost but manual loading), AXINAR wood boilers are an alternative choice.
