Controlled domestic ventilation

Heat recovery systems need optimally insulated air ducts to avoid condensation and realise a safe and healthy indoor climate.

Homes are becoming better insulated. This makes it increasingly important to ventilate in a continuous and controlled way. After all, moist and dirty air must be removed to prevent the home becoming a breeding ground for bacteria, house dust mites and mould.
This exhaust air from the house contains a great deal of heat. A heat recovery ventilation system (HRV) and heat pump system are used to retain this heat and prevent unnecessary energy losses.

A common problem with heat recovery ventilation systems is condensation on the supply and return ducts. This is caused by large temperature differences between indoor and outdoor air. To maintain a healthy indoor climate and prevent damage to the HRV system, it is important to properly insulate the supply and return ducts with an impact-resistant, vapour-tight and water-repellent ducting system.

Ventilation systems and heat pumps produce emission noise. Good insulation of the supply and return ductwork can greatly reduce this noise, which is often considered a nuisance.
