Why choose an Air Source model?

Instead of providing just a single source of fresh air into a property, usually located in a hallway or landing, the MIV® Air Source has the ability to supply fresh, filtered air via multiple inputs into areas with greater requirements for ventilation. Highly efficient, inputs can be situated in rooms affected by increased levels of humidity, such as the kitchen, bathrooms and other wet rooms. Fresh air inputs can also be located in bedrooms or living spaces that suffer from particularly bad condensation or in the bedroom of an asthma sufferer to reduce the level of humidity and therefore the house dust mite population – a known trigger for allergies and asthma.

5 Year Guarantee

With 5 year ongoing maintenance free warranties and superior long life filters the unit achieves the lowest life cycle costings. All repairs, maintenance and component replacement is carried out simply and quickly by exchanging the filters and consumable items. The worn out components are then taken back to the factory to be recycled thus reducing the impact on landfill and saving millions of pounds in replacement costs.

Pre-Heater and Hours Run Meter

The integral pre-heater is designed to temper the incoming air during periods of low external temperatures. A sensor monitors incoming air and pulses the heater to ensure temperatures are held to pre-set minimums. Three independent safety cut-out devices shut down the heater in the event of fan failure. The heater facility is controlled independently from the fan by a conveniently positioned enable/disable switch. For monitoring of operational life and verification of usage, an integral Hours Run Meter is fitted.

Unique EnviroVent Mini Diffuser

Available with the MIV® Air Source is the stylish EnviroVent energy saving diffuser, providing an innovative alternative to standard ceiling vents. Simple to commission and install, the diffuser is designed with easy to clean filters, which prohibit contaminants entering the property. These also act as a second defence against pollen and other airbourne contaminants in conjunction with the unit’s internal filter. Side panels can be easily blanked off according to its location.

Solar Gain and Summer Cooling

The MIV® Air Source takes maximum advantage of the benefits of solar gain from the loft space throughout the year. Solar gain is the natural accumulation of heat from the sun on bright days. Temperatures in the loft are on average 3°C higher than outside and as the unit draws fresh air from the loft and delivers it into the property, this results in a saving of around 500 Kilowatts of energy per year in an average family home – equating to significant savings in annual heating costs.

Going beyond traditional input ventilation, the MIV® Air Source has the facility to source cooler air from outside the building when the temperature in the loft space rises above 25°C. Detecting the rise in temperature, the unit starts to draw air from atmosphere via a temperature controlled diverter mechanism. This not only provides efficient perception cooling into the property during warmer weather, but also maintains the required level of ventilation continuously throughout the year. This facility is greatly beneficial for properties affected by high levels of Radon.

Health Benefits

With improved building features in our homes, such as cavity wall insulation, double glazing and draught proofing ‘natural ventilation’ is prohibited. Stale air is trapped causing streaming windows, which ultimately leads to musty smells, dampness and mould growth.

These mould spores are known allergens and become airborne at the slightest disturbance. The microscopic spores are then inhaled and can trigger respiratory problems such as asthma, dust allergies and hayfever.

The EnviroVent Loft Mounted Unit draws fresh air into the dwelling from outside and filters it before being delivered into the property. Moisture-laden air is diluted, displaced and replaced with clean, tempered and filtered air. This eliminates or reduces surface condensation, which causes mould growth, providing a significant improvement in the health of asthma sufferers and general indoor air quality.

Make it MIV®
Multi-Zone Destratification

Warm air accumulates at ceiling level and is normally lost through windows and extract fans. This air can be up to 7°C higher than the internal air at ground level. By introducing an almost imperceptible fresh air supply into multiple rooms, the MIV® Air Source redistributes heat around the home by pushing the heat back down and keeping the convection currents moving to reduce space heating costs. By saving only 1 degree of heat the multi-zone destratification will cut fuel bills by 10%.
