How to choose a gas boiler for a 200 m² house 2026
A gas boiler on a 200 m² house directly affects 800-1,800 AZN in annual costs. Right power, brand and technology. 2026 guide.
1. Sizing
Rule: 1 kW per 10 m² with good insulation. For 200 m² you need 24-28 kW. Plus pool heating and hot water — 30% reserve = 30-35 kW. Less — can't cope in cold snaps, more — burns extra.
2. Condensing vs classic
Condensing — 93-98% efficiency, 30% less gas. Price 1,200-2,800 AZN. Classic — 82-87% efficiency, 750-1,500 AZN. Condensing pays back in 3-4 seasons. Only condensing is recommended for new builds.
3. Brands
On market: Baxi (Italy, mid); Ferroli (Italy, quality); Bosch (Germany, premium); Vaillant (Germany, premium+); Ariston (Italy, mid). Service centre in Baku — required.
4. Extra functions
A modern boiler should have: 1) Modulation (auto power adjust); 2) Wi-Fi (smart-home integration); 3) Radiator thermostats (per room); 4) Anti-freeze mode (winter protection); 5) Online diagnostics (service forecast).
Boiler for 200 m²
| Type | Efficiency | Price | Gas/year |
|---|---|---|---|
| Condensing premium | 97-98% | 2,200-2,800 AZN | 550-750 AZN |
| Condensing mid | 93-95% | 1,200-1,800 AZN | 620-820 AZN |
| Classic | 82-87% | 750-1,200 AZN | 820-1,100 AZN |
| Classic cheap | 75-80% | 500-750 AZN | 1,000-1,350 AZN |
A gas boiler is a 15-year investment. A condensing unit saves 4,000-6,000 AZN over 15 years, more than covering the classic-price gap. Buy only condensing — right 2026 call.
