A heat recovery ventilator (HRV) is the heart of a modern ventilation system. It not only supplies fresh air to your home but also preserves indoor heat, reduces energy bills, and ensures a comfortable microclimate. However, choosing the right HRV requires careful consideration. Let’s explore the 7 essential factors you should evaluate before making a purchase.
1. 💨 Airflow Capacity (m³/h)
This is a fundamental metric that shows how much air the unit can handle per hour.
- For an apartment of 50–70 m²: 150–250 m³/h
- For homes over 100 m²: 300 m³/h and above
❗ If the airflow is too low, it won’t ventilate properly; if it’s too high, it may lead to excessive energy use and noise.
2. ♻️ Heat Recovery Efficiency (HRV Efficiency)
Efficiency shows how much heat is transferred from the outgoing air to the incoming fresh air.
- Good HRV units have an efficiency of 75% to 95%
- Higher efficiency = lower heating and cooling costs
💡 In Uzbekistan’s colder months, a high-efficiency unit is crucial to retain warmth indoors.
3. 🔇 Noise Level
A ventilation system should operate quietly, especially in bedrooms and children’s rooms.
- Ideal noise level: under 25 dB in night mode
- Up to 35 dB is acceptable during daytime
Look for models with sound insulation and night mode features.
4. ⚙️ Control Options
HRV systems vary in how they can be controlled:
- Manual — simple, basic models
- Digital — control panels with settings
- Wi-Fi or Mobile App — smart and convenient
📱 App-based control allows you to adjust settings remotely and monitor air quality in real-time.
5. 📏 Size & Installation Type
HRV units come in various formats:
- Wall-mounted — compact and room-specific
- Central systems — for entire homes, ducting required
- Ceiling-mounted — hidden in ceilings or utility spaces
Choose based on your home’s layout and available space.
6. 🧼 Air Filtration
High-quality filters protect against dust, allergens, and pollution:
- G4 filter — traps large particles
- F7 filter — captures pollen, fine dust
- HEPA filter — excellent for allergy sufferers or urban homes
Make sure the filters are easy to replace and locally available.
7. 💰 Price vs. Payback
Prices vary based on performance, brand, and features:
- Entry-level models: from $300–500
- Premium systems: up to $1000+
💡 Thanks to energy savings, most systems pay for themselves in 2–5 years, especially in well-insulated homes.
