How to Choose the Perfect Ventilation System for Your Home
Retrofit Ventilation Solutions
Indoor air quality has never been more important. The average person spends the majority of a 24-hour period within their house yet how many of us consider the air that we breath during this time?, This is why retrofit ventilation solutions could help improve the indoor quality in your home.
What is Natural Ventilation?
Traditional housing relied on natural ventilation as dictated by the regulations at the time of building. Natural ventilation is the provision of air in and out of a property via wall vents, window trickle vents and localised extractor fans.
Natural ventilation has its downfalls, often vents remain closed therefore we do not get the fresh air required in the dwelling. At the same time often the local extractor fan which should be extracting at a rate of 15l/s in a bathroom is often not effective or we turn it off at the isolator because its ‘noisy’.
New builds have now moved on to a more efficient mechanical means via heat recovery ventilation systems (MVHR) and centralised mechanical extract ventilation (MEV).
MVHR acts as the lungs of the property continuously supplying fresh air and extracting stale air simultaneously whilst recovering heat.
MEV acts as one continuously running extract system which in turn results in fresh air being drawn in from outside through a trickle vent in the window.
Both the MVHR and MEV options are ducted systems that require duct from the unit to each of the rooms they serv. This makes them very difficult to retrofit unless you are in a bungalow or performing renovation back to the shell of the dwelling.

What is Single Room Heat Recovery Retrofit Solution?
Single room heat recovery units are a continuously running, low energy, ultra-quiet, alternate flow supply, and extract fan with heat recovery for use in habitable areas such as living rooms, bedrooms, dining rooms, basements, and hallways.
The complete unit consists of an external grille, telescopic duct, filter protected ceramic core, room mounted alternate flow and aesthetically designed grille.
How it works
The continuous running decentralised heat recovery units (aircycle ONE+) transfer thermal energy from air extracted from indoor rooms to incoming fresh air. Two units can work synchronised with balanced air flows and top acoustic comfort, controlled through a remote IR controller. The system can also include a single flow decentralised unit mounted in the wet room like the airstream DMEV. No central ducted air distribution system is needed.
Energy saving: the preheated supplied fresh air and continuous air changes reduce the demand for additional heating. Aircycle ONE and airstream DMEV are equipped with EC brushless motors which significantly reduce the electricity consumption.
Indoor Air Quality: By constantly changing the air within the property you are removing Co2 and other pollutants and replacing them with fresh air.

Airstream DMEV:
Operation
— Every 70 seconds the unit alternates between supply and extract fan modes.
— When in extract mode the unit’s high efficiency ceramic heat exchanger collects and retains heat from the extracted air. The majority of this heat is then transferred to the incoming air during supply mode.
— This method of operation avoids the short circuiting of air that can often happen with conventional single room heat recovery units, resulting in much more effective room ventilation.
— Units can also be set to work in harmony with each other e.g. when a unit in one room is extracting air another unit in another room can be set to supply air. This can greatly enhance cross ventilation and ventilation effectiveness in a home.
