£1,666.80  incl VAT


MRXBOXAB-ECO4 is the higher duty model in our range of compact wall-mounted heat recovery systems, suitable for larger properties with a kitchen and up to 8 wet rooms. Fully compliant with building regulations, and fully customisable to suit your home, the unit will improve your indoor air quality, help you save on energy with ultra-low running costs, and prevent condensation in your home.

Industry-leading heat exchange technology means that 95% of the heat from extracted air is recovered, reducing your energy bills through the year. The latest generation of low-watt DC fans provide ultra-quiet operation with reduced power consumption and running costs, so you can continue to save energy and money throughout the year. A summer-bypass facility comes as standard providing background cooling during the warmer months.

Due to its potential to save energy, this high duty system boasts some of the best SFP and SAP scores, which will help you meet the Code for Sustainable Homes level 3 or above and meet Part F and L Building Regulations. The compact, lightweight MRXBOXAB-ECO4  has been specifically designed for wall installation and is easy to install and maintain with accessible filters. The low-maintenance operation means that you can fit and forget your unit with filters that require changing every five years.

Additionally, a five year warranty gives extra peace of mind. The model is compatible with Nuaire’s Touch Screen Controller, giving you added freedom to tailor the system’s performance to suit your home and your lifestyle. With simple, intuitive instructions, you can programme settings to save further energy based on the changing seasons or your changing needs.
