Mitsubishi Electric says its new heat recovery ventilation unit is a simple way help improve the indoor air quality in the home.

The company has enjoyed success in the commercial sector with its Lossnay system and has now translated the Mechanical Ventilation with Heat Recovery (MVHR) for residential properties.
‚ÄčJanvi Patel, ventilation expert at Mitsubishi Electric, said: “Our new VL-50 Lossnay unit can be fitted to an exterior wall and ducted out using a single pipe. It will then capture up to 84% of the heat energy that would otherwise be wasted.”

Lossnay achieves high levels of heat recovery by using a fine paper core, which allows the heated outgoing air to transfer this heat energy to bring the incoming air closer to the room temperature, thereby keeping the inside fresh without wasting energy. Pollutants, smells and even outdoor noise are filtered out by the unit, meaning that the inside is both fresh and comfortable, whilst the heat recovery element also means it is highly energy efficient.

A single pipe connection to the outside is needed for the unit, making it ideal for retrofitting into existing buildings.  The VL-50 is available as a pull-cord, hard-wired, or wireless remote controlled unit and measures just 52cm by 24.5cm. The unit can be fitted vertically or horizontally to suit the interior décor and provide installation flexibility and needs no pipework other than the connection through the wall to the outdoors.

Patel added: “Lossnay recovers both latent heat and sensible heat, meaning the incoming air is comfortable and the home doesn’t suffer from static or dryness. It’s all about increasing comfort whilst minimising the energy needed to do so.”

The units are priced from £208 and boast low sound levels, low power consumption and easy maintenance. More details can be found on Mitsubishi Electric’s document library.
