Ventilation
standards and efficiency targets in recent years, which have ensured new homes are warmer and more energy efficient, but they are unable to breathe naturally. Part F of the Building Regulations states that there are four categories of
ventilation product that an installer can choose from: Intermittent extract fans and background ventilators, passive stack ventilation, centralised or de- centralised mechanical extract, or Mechanical Ventilation with Heat Recovery (MVHR) Each have their own advantages and disadvantages, with different
categories better suited for individual properties, requirements or circumstances, but manufacturers have responded to the challenges with continued development of products across all categories.
Harnessing the power of MVHR With growing awareness of indoor air quality, however, it is MVHR which seen the most rapid development and deployment in recent years. 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 whilst addressing health concerns through a cost-effective, mechanical, balanced ventilation system.
In fact, 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, whilst constantly supplying fresh filtered air. To increase their effectiveness, the latest MVHR systems from leading manufacturers offer a host of features including ultra-fine filters, PIR sensor activity for enhanced efficiency and cold-climate pre-heating. Uniquely, Xpelair’s Natural Air 180 also uses adaptiflow technology to deliver a constant volume of extracted air, thus giving homeowners assurance of the performance being delivered.
Ingredients for clean indoor air Ventilation is not a one-size-fits-all approach and whichever sector your customers operate in, the one constant of a modern ventilation system is the need to balance energy efficiency with management of indoor air quality. With modern ventilation systems, evolving Building Regulations and a
greater focus on management of indoor air quality, this is now more accessible than ever.
xpelair.co.uk We can expect smart water cylinders, ventilation and air treatment
products such as Mechanical Ventilation & Heat Recovery to be connected to a whole-house heating and comfort system in the near future, not forgetting the energy source itself like a boiler or heat pump.
