Recovery Systems

Mechanical Ventilation with Heat Recovery (MVHR) works by recovering heat from extract air that would normally be expelled to the atmosphere and transfers this heat to fresh air being drawn into the property via a heat exchanger. The Heat Recovery Ventilation (HRV) system then distributes this throughout your property via a network of ducting.

Benefits Of Heat Recovery Systems

The Heat Recovery Ventilation system continually extracts from the wet rooms, boosting if necessary, removing the pollutant air quickly and effectively at its source. This air then passes up through the network of ducting and travels through a heat exchanger where its heat passes to the fresh filtered air which is being brought into the property at the same time.

 continuous balanced ventilation with improved indoor air quality, providing a healthy living environment and preventing condensation by keeping moisture levels low

Recovering the heat from your extract air instead of simply sending it to atmosphere can lead to significant energy savings by reducing the cost of your heating bill

With the growing trend towards property air tightness, HRV systems cancel out the need for background ventilators

Brookvent’s aircycle HRV systems are SAP approved and succeed in reducing CO2 Dwelling Emission Rate (DER). Specifiers, Low Carbon Consultants and Architects can gain SAP points for your property by using our product’s specific performance information instead of standard default information provided in the SAP register


The ducting is brought to each habitable room and each wet room within your property. Each wet room is fitted with an extract valve and each habitable room with a supply valve.

 it is absolutely vital to have your Heat Recovery Ventilation (HRV) system installed properly. This begins with a good design. Nu Heat is very experienced in system design and provides professional guidance on ducting routes across a wide variety of residential properties

HRV systems are generally installed in two stages – 1st and 2nd fix. At 1st fix stage the majority of the ducting is installed, as per the system design, and any wiring requirements are provided for, including the tracking of remote sensors such as humidistats. At 2nd fix stage the system is installed, all ducting and wiring is connected, ceiling valves are fixed to the ducting point in each room, and the condensation drain from the system is installed. Finally the system is commissioned as per the appropriate Building Regulations

the size and location of the HRV unit is extremely important. The unit must be fit for purpose, taking into consideration the size of the property and associated airflow rates. Nu Heat installs to the highest standards to achieve best performance.

Nu Heat issue commissioning certificates detailing the measured installed airflow performance of each system against design requirements. Finally, each unit’s operational and maintenance requirements are clearly defined and demonstrated to ensure competent user operation and optimum system performance. At Nu Heat we have adapted our products based on customer feedback so they can be installed easily, often in compact spaces, and accurately commissioned.
