Heat Recovery Ventilator (HRV) — Operating Principle
A recuperator (heat recovery unit) transfers heat from exhaust air to incoming fresh air without mixing the two streams.
---
How It Works
Two airflows:
Exhaust air (warm, from indoors)
Supply air (cold, from outside)
They pass through a heat exchanger:
separated by plates or channels
no direct mixing
heat transfers through the material (conduction)
Result: → supply air is preheated
→ exhaust air is cooled
→ overall heat loss is reduced---
Types of Recuperators
1. Plate Heat Exchanger
aluminum or plastic plates
efficiency: ~60–90%
no moving parts
2. Rotary (Wheel) Heat Exchanger
rotating drum
transfers heat and some moisture
efficiency: up to ~85–90%
3. Counterflow Heat Exchanger
air streams move in opposite directions
highest efficiency: up to ~95%
---
What Is Transferred
heat (primary)
sometimes moisture (in enthalpy units)
---
Efficiency Example
outside: 0°C
indoor: +22°C
after recovery: ~16–20°C
---
Advantages
reduced heating energy demand
continuous ventilation without major heat loss
improved indoor air quality
---
Limitations
frost formation in winter (needs bypass or preheater)
filter maintenance required
upfront cost
---
Core Idea
A recuperator doesn’t generate heat — it recovers and reuses it.

Should We All Be ‘#HouseBurping’?
The German practice of “#lüften” is gaining traction on social media. It may improve your home #AirQuality.
By Dorie Chevlen, Jan. 29, 2026
Excerpt: "Experts say lüften actually works. The Environmental Protection Agency recommends opening windows to reduce the concentration of volatile organic compounds [#VOCs] in the home, which are released by a vast array of household items, including furniture, mattresses, cosmetics and cleaning products. These compounds can cause adverse reactions like headaches, itchy eyes and breathing problems.
"According to Dr. Parham Azimi, research associate at the Harvard T.H. Chan School of Public Health, there’s also reason to believe airing out a home regularly could help control household #mold. In his research, keeping windows closed correlated with a higher likelihood of mold.
"Dr. Joshua Nosanchuk, a professor and microbiology researcher at Albert Einstein College of Medicine and an infectious disease physician at Montefiore Health System, said that better #ventilation could eliminate many airborne toxins that cause people irritation in the U.S. 'Part of the problem is that we hermetically seal our houses. We don’t want the air conditioning to get out and we don’t want the heat to get it out,' he said. 'No one opens their windows.' "
