Mechanical Ventilation Systems with Heat Recovery (MVHR)

What is Mechanical Ventilation with the use of Heat Recovery (MVHR)?

Mechanical ventilation with heat recovery (MVHR) is a type of ventilation system that works by extracting moisture and air from a building and replacing it with fresh air. The system is designed to recover heat from the air that is being extracted and transfer it to the incoming air. This way, the building stays warm while maintaining an adequate supply of fresh air.

The traditional ventilation systems used in homes and buildings involve opening windows and doors to allow a natural airflow. While this method can be effective in certain conditions, it leads to a lot of energy wastage. Open windows and doors can cause indoor heat to escape during colder months, leading to increased energy costs and greenhouse gas emissions.

MVHR, on the other hand, is much more energy efficient. The system uses a heat exchanger to efficiently transfer the heat from the extracted air to the incoming air, which maintains the temperature in the building.

The system is also designed to filter the incoming air, which means that the indoor air is cleaner and healthier to breathe. Mechanical ventilation with heat recovery can reduce the risk of condensation, mould, and damp, which are common problems in many buildings.

Another significant advantage of this type of ventilation is that the system is designed to run quietly, and the indoor environment remains peaceful and undisturbed.

MVHR Ventilation Process

The system works by continually removing polluted air from each wet room through an extractor valve, boosting when necessary. As it does, the extracted air passes through a heat exchanger. This component transfers the recovered heat to the fresh air coming in, which is sent to a supply valve in each habitable room through ducting.

Benefits of heat recovery ventilation systems:

Keeps your home well ventilated without lowering temperature.
Saves you money by reducing the cost of heating your property.
Improves air quality for a healthier living environment.
Protects your home and furniture against moisture and pollutants.
Can easily be installed in both new and existing properties.

Types of Mechanical Ventilation

There are several types of mechanical ventilation with heat recovery (MVHR) products available on the market. These include:

Centralised MVHR systems: These systems are designed to supply and extract air to and from multiple rooms or areas of a building. They typically use a ducting to distribute air to various rooms.
Decentralised MVHR systems: These systems are a single flow decentralised mechanical ventilation unit for continuous running.
Whole House Heat Recovery Systems: These systems are designed specifically to be highly energy efficient with minimal heating requirements. They work by extracting and then supplying fresh air throughout all rooms, retaining heat while removing possible risk of condensation and mould.
Single Room Heat Recovery Systems: These are stand-alone units that are designed to ventilate a single room or area. They alternate flow supply and extract fan with heat recovery for use in habitable areas such as living rooms, bedrooms, dining rooms, basements and hallways.
Extract Fans: Mainly used in bathrooms or kitchens , they remove the stale air room the room and extract it outside, which can help maintain indoor humidity levels, condensation,and mould.

In conclusion, homes and buildings that use traditional ventilation systems can gain a lot from switching to mechanical ventilation with heat recovery. This system can lead to significant energy savings, a healthier indoor environment, and a reduction in greenhouse gas emissions. It is a perfect solution for those who want to live sustainably and efficiently.
