For a 200 sqm detached house or apartment, the boiler must cover significant volume and typically multiple heating zones. Choosing kW must be careful, oversizing means wasted consumption and frequent on-off cycles, while undersizing means you’ll never heat enough during cold winters.
How Many kW You Need for 200 sqm
| Building characteristics | Required Power |
|---|---|
| Good insulation, Zone A–B, radiators | 20–26 kW |
| Medium insulation, Zone B–C | 26–36 kW |
| Older construction or Zone D | 36–48 kW |
| With domestic hot water (300L+ tank) and 2nd floor | +5–8 kW additional |
Recommended AXINAR Models for 200 sqm
1. AXINAR PELIT PL30, The Most Popular Choice
Covers the majority of homes 170–230 sqm with medium insulation in Zone A–B. The most proven model in this category.
- Nominal 30 kW, efficiency >92%
- Multi-pass flue gas
- Automatic auger cleaning, weekly schedule
2. AXINAR PelletWork PW30, All-in-One 30 kW
Same power as PL30 but in unified form. Ideal for new installations where quick setup matters.
- Boiler + tank + circulators + panel in one unit
- Compact, installs in smaller boiler rooms
- Single warranty, single maintenance
3. AXINAR PELIT PL45, For Colder Zones or Older Homes
If you are in Zone C/D or the house has low insulation (pre-1990 construction), the 45 kW gives you comfort without constantly pushing the boiler at 100%.
- Nominal power 45 kW
- Multi-pass flue gas
- Lower operating cycles, longer service life
Indicative Annual Pellet Consumption (200 sqm)
- Zone A: 1,400–1,800 kg/year
- Zone B: 1,800–2,400 kg/year
- Zone C: 2,300–3,000 kg/year
- Zone D: 2,900–3,800 kg/year
At 200 sqm it’s worth considering a pellet storage tank of 1,500 kg capacity (silo), giving ~6 months autonomy on a single delivery.
What You Need to Know Before Buying
- Multiple zones: 200 sqm typically have 2+ heating zones (ground floor/upper floor, bathrooms, DHW). You need a 3-zone control panel or more.
- Pellet storage: For 200 sqm, an external 1,000–1,500 kg tank is more practical than sacks. Reduces pellet purchase cost by ~15% (bulk).
- Chimney: Ø150–180mm double-walled stainless steel. Height at least 5m above roof for proper draft.
- Warranty: All AXINAR boilers come with 5 years factory warranty on the body plus technical support throughout Greece.
