Ventilation can be very important to help reduce condensation, however on cold days traditional ventilation systems remove warm air from the house which inevitably draws cold air back in.
Ventilation with heat recovery, also known as MVHR (mechanical ventilation with heat recovery), is a system designed to provide fresh air into a home while also recovering the heat that is typically lost during the ventilation process.
The system works by extracting stale air from the home and passing it through a heat exchanger. This heat exchanger transfers the heat from the stale air to the incoming fresh air, which is then distributed throughout the home. By recovering the heat that would normally be lost, the system can help to reduce the amount of energy needed to heat the home, which can lead to lower energy bills.
There are a number of benefits to using a domestic ventilation system with heat recovery. In addition to the energy savings, these systems can help to improve indoor air quality by removing pollutants and allergens from the air. They can also help to reduce humidity levels, which can help to prevent mold and mildew growth.
However, currently these systems can be expensive to install and maintain, and may not be suitable for all homes.
