Effective ventilation can be key to an individual’s health and wellbeing and an efficient way to protect against indoor air pollutants. Poor indoor air quality is something that affects much of the UK population. Here Lee Stones, product marketing manager for Xpelair, explains how solutions such as Mechanical Ventilation with Heat Recovery (MVHR) can help.
It is estimated the UK population spends 90% of its time indoors and while many understand the detrimental impact of poor pollution outdoors, few consider the effect of the quality of the air we breathe inside our homes. The biggest cause of poor indoor air quality is Volatile Organic Compounds (VOCs), which can be emitted from a whole host of everyday items such as furniture, carpets, paints, cleaning products and even building fabrics and materials.
VOCs can be detrimental to a person’s health, especially when exposed to them for long periods of time. They can also aggravate pre-existing health conditions and cause fatigue, dizziness and headaches. The effects will be further increased as housebuilders create ever more insulated homes, leading to a decrease in natural ventilation and even more air tightness in properties. This is why mechanical ventilation is crucial.
One option is combining Mechanical Ventilation and Heat Recovery, offering the opportunity to extract air from the building through a central heat exchanger and recover heat back into the air supply. The concept of MVHR is gaining traction as a method of enabling energy recovery while addressing health concerns through a cost-effective, mechanical, balanced ventilation.
MVHR is fast becoming the only ventilation system that meets building requirements. It offers the benefit of providing ventilation that both supplies and extracts air through a property, while constantly supplying fresh filtered air. Ideal for new builds, MVHR is suited to smaller homes, flats or apartments where insulation levels are often high.
An innovative solution to the MVHR sector is Xpelair’s Natural Air 180, which truly raises the bar in modern domestic ventilation. The system is Xpelair’s first whole-house MVHR unit and is completely new to the market providing an efficient and flexible approach to ventilation. With the use of ultra-fine G4 filters, the unit helps to significantly improved indoor air quality and eliminate condensation and odours.
The unit offers in-built flexibility for customisation to meet non-standard situations. From NOX filtration for optimised safety, a particularly relevant issue for inner-city dwellings, through to PIR sensor activity for enhanced efficiency and cold-climate pre-heating, each unit can be customised with an extensive range of Xpelair ancillaries.
Another advantage is the unit’s Intelligent Adaptiflow Sensing, through which the motor continually assesses the performance of the impeller and, when there is a consistent change in airflow, adjusts the fan speed fan to maintain a constant volume of extracted air. Its unique, active humidistat responds to rapid increases in humidity, important for kitchen and bathroom ventilation.
The Natural Air 180 is the ideal answer to changes in building regulations, especially with housebuilders striving to achieve the Passivhaus standard. Natural Air 180 makes a contribution to the government’s pledge of a low carbon future as it is listed on the Passivhaus database, demonstrating the unit’s ability to facilitate the planning and performance of a building to the required standard of a reduced ecological footprint.
At 552mm x 609mm x 285mm, Natural Air 180 occupies less room than similar products on the market. While its lightweight construction in two pieces, instead of the traditional one, make it easier to handle and fit.
With an increased focus towards Passivhaus and heating and ventilation requirements changing it is a key time to provide solutions that will increase ventilation and improve indoor air quality.
