Ventilating an Absheron house: salt, wind and heat recovery 2026

2026-09-03 · 4 min read · MARDECO

Ventilation on Absheron must solve three unique problems: salt, strong wind, summer heat. The right system saves 30% on gas and makes air 5× cleaner. 2026 prices.

1. Three unique Absheron problems

1) Salt aerosol — sea wind carries it into the house, corrodes electronics; 2) Strong wind — plain windows blow open, dust flies in; 3) 40 °C summer — a plain fan won't do, AC needed. All three solved by a central heat-recovery unit.

2. What HRV means

Heat-recovery ventilation (HRV / ERV) — exhaust air passes heat (85% winter, 75% summer) to incoming air. HEPA H13 filtration removes salt and dust. Result: -30% gas in winter, -25% AC in summer, +5× cleaner air.

3. 2026 prices

For a 220 m² villa: mid HRV (Systemair, Vents, Aerauliqa) — 3,500-6,500 AZN kit + 1,800-3,500 AZN duct install. Total 5,300-10,000 AZN. Premium (Zehnder, Swegon) — 8,000-14,000 + 3,000-5,500. Payback 7-10 years on gas alone, plus air-quality value.

4. Filters

Absheron needs: F7 (dust) → H13 (0.3 µm, PM2.5 and salt) → carbon (sea smell and diesel). Replaced every 6 months — 120-280 AZN/year.

Ventilation — 220 m²

On Absheron ventilation is infrastructure, not a «feature». An 8k AZN system saves 500-800 AZN/year gas and 300-500 AZN/year AC and makes the house 5× safer for allergics, asthmatics, kids.

Five HRV choice points

• Efficiency — 75% winter minimum.
• Filtration H13 HEPA included.
• Noise — < 35 dB.
• CO₂/humidity sensors, auto control.
• Warranty 5 years+.
