How to optimally prepare the heat recovery unit for the winter season

Winter weather presents challenges for mechanical ventilation with heat recovery (MVHR) systems, such as low temperatures and increased humidity, which can impact their efficiency. To maintain the unit’s safe and efficient operation, it is essential to properly prepare it for these harsh conditions. Here are the steps to help you prepare your MVHR unit, along with the protective measures we have implemented in the ARIA VITALE device against extreme winter conditions.

Winter Protection in ARIA VITALE

The ARIA VITALE model is equipped with a three-stage frost protection system that automatically reacts to extreme conditions. It consists of:

1.Preheater: This heats the air entering the heat exchanger, preventing the unit from freezing.

2.Airflow regulation: Optimized flow control ensures continuous operation without the risk of freezing.

3.Bypass: This activates in exceptionally low temperatures to further support the system.

Step-by-step: How to Prepare Your MVHR for Winter

Step 1: Check the insulation of the ventilation system

It is crucial to ensure that the air distribution system is well-insulated. Proper insulation prevents heat loss and condensation in the ducts, which could lead to damage and reduced efficiency.

Step 2: Check the siphons

Verify that the siphons are correctly connected and there are no leaks. Ensuring proper condensate drainage is key to avoiding problems with excess water that often arise during the winter. Improper condensate management can cause trays inside the units to overflow and disrupt the system’s operation.

To prevent this, we have included detailed information in the ARIA VITALE manual about proper siphon connections based on the unit’s mounting position (wall, ceiling, or floor).

Step 3: Condensate drainage and MVHR installation in the attic

If the unit is installed in the attic, it’s a good idea to secure the condensate drainage with heating cables and good insulation to prevent freezing and drainage issues.

Step 4: Set the unit to minimize energy consumption

In extremely low temperatures (below -15°C), it is advisable to reduce the MVHR’s output to minimize energy consumption while ensuring the device operates efficiently.

Step 5: Regular maintenance

Regularly maintain the unit, especially before the winter season. Ensure all components are functioning properly and are well-protected against extreme weather conditions.

By closely following these guidelines, you can enjoy stable and efficient operation of the ARIA VITALE unit even in harsh winter conditions. If you have any additional questions or concerns, feel free to contact our service department.
