Ventilate with closed windows, eliminate mold, humidity, and health risks.
Did you know that up to 40% of heat escapes from a home through ventilation? Regulus heat recovery ventilation solves this problem intelligently. It brings in fresh air and recovers up to 93% of heat from outgoing air. The result? A healthier environment without mold and dust mites, more oxygen, and lower heating bills.
In summer, heat recovery ventilation units also pleasantly pre-cool the space thanks to an automatic bypass. During operation, they are extremely quiet, with noise levels of only 20 dB(A), like the ticking of a watch.
Ventilate all year round without unnecessary losses and without opening windows. And when needed, our service support is available across the Czech Republic.

Absolutely. With current energy prices, the savings are even more significant than before. Ventilation heat losses account for about 30–40% of total losses in typical homes, so the savings are substantial. The payback period is shortening due to rising energy prices – currently around 6–8 years.
You’ll notice it in the air quality. Without opening windows, issues with humidity and condensation disappear. Our units also display real-time values for temperature, humidity, and air quality.
This is a common myth. Properly designed systems help maintain optimal humidity levels. Advanced units may include enthalpy exchangers that recover not only heat but also moisture.
Our units are among the quietest on the market. Depending on the ventilation mode, noise levels are around 20 dB(A), comparable to the ticking of a watch. A night mode with reduced performance can also be set. With proper design and installation, including silencers, the system will not disturb you even at night.
Maintenance is minimal and very simple. The main task is regular filter replacement, which you can easily do yourself – typically 2–3 times per year. One set of filters costs about €20–40 depending on the unit. We recommend an annual service check by a technician, who will inspect the system, clean the heat exchanger, and perform any necessary maintenance. Total annual costs are only a fraction of what you save on heating.
Our units are equipped with an automatic summer bypass. The system filters incoming air without heat exchange. You can also use night cooling – when it’s cooler outside, the system increases airflow to help cool the house. Intelligent control ensures the heat exchanger is only used when beneficial.
Yes, it’s an ideal solution. Controlled ventilation ensures proper air exchange throughout the home, removes excess moisture, and prevents condensation. Our units include humidity sensors that automatically adjust ventilation intensity.
It depends on your situation. Local units are more affordable and suitable for apartments or individual rooms, but they don’t offer the same level of comfort as central systems.
For family houses, we recommend central systems that ensure balanced ventilation, higher efficiency, and easier maintenance.
High-quality units typically last at least 15–20 years. Only filters need regular replacement (2–3 times per year). Fans last over 10 years, and the heat exchanger has a virtually unlimited lifespan with basic maintenance.
