Improve indoor air quality with fresh air all year round.
Modern building regulations are driving home to be more energy efficient; homes are increasingly more insulated and airtight. This is good news in terms of the home energy performance, and comfort but poor ventilation can sometimes be an issue as natural air can no longer easily migrate into the home.
Natural ventilation methods, such as windows, fans and trickle vents, can result in significant heat loss, creating a conflict between good air quality and energy efficiency.
However, buildings without adequate ventilation can suffer from poor air quality, damp and mold, affecting the health and wellbeing of its occupants. Fortunately, Ventilation Solutions that also combine Heat Recovery offers ideal solutions.
Our systems will quietly and efficiently provide the home with fresh, filtered air all year round, improving the indoor air quality and reduce dust and allergen levels.
Ventilation is the process of extracting stale air from a building while supplying fresh, clean air from the outside and ridding the property of, among other things, smoke, cooking odours and chemical pollutants.
Furthermore, ventilation prevents the build up of moisture which could otherwise lead to damp and black mould, damaging the property and causing allergic reactions and respiratory issues.
Even without excess moisture, poor air quality can negatively impact us, leading to headaches, asthma and sinusitis among other problems.
Good ventilation therefore is important to our everyday quality of life and, with its dual purpose of temperature control, well ventilated spaces provide us not only with health benefits but a comfortable environment in which to live.
In addition to providing good air quality, MVHRs are more efficient that other ventilation systems with a low energy cost, leading to a reduction in your carbon footprint and energy bills. Furthermore, they are compact, lightweight and with industry-leading noise levels meaning that they fit discreetly in your home and provide no adverse impact on sound quality.
Mechanical ventilations systems remove wet or polluted air from your property and replace it with cleaner fresh air from outside, creating a healthier environment in the home, however this can make it difficult to retain heat, and a conflict between air quality and energy efficiency.
Mechanical Ventilation with Heat Recovery (MVHR) systems, however, recover heat (and cooling in summer) from extracted air and transfer it to the new fresh air being drawn in from outside. High efficiency technology recovers up to 95% of the heat that would otherwise be wasted, improving energy efficiency and helping you save on your heating bills, whilst providing good air quality for you home.
Airtight buildings with little ventilation often experience high condensation, mold, dust mites and unpleasant smells, and it is well documented this is linked to harmful respiratory conditions and building fabric damage. MVHR systems solve this by replacing moist, stale air with clean filtered air, a heat recovery system creates high quality air conditions without sacrificing warmth.
Installing an MVHR system solves the issues arising from poor air quality.
MVHR systems work by removing polluted air from ducted room which can run continuously, linked to intelligent sensors, and boosted when necessary, during high levels of humidity. As the air is extracted is passes through a heat exchanger which recovers the energy from the air.
The heat exchanger then transfers the heat energy to the supply air from outside before it is distributed to the ducted rooms providing a fresh, energy efficient environment.
The heat exchanger prevents any cross contamination between the stale and fresh.
Mechanical extract ventilation (MEV) systems constantly remove moisture-laden air from the kitchen and wet rooms, like toilets and bathrooms. This air is extract from a single outlet such as an external wall louvre or roof vent. As well as clearing polluted air, the system causes a drop in pressure within the property that draws fresh air in from windows and other areas of the home.
MEV systems can be linked to various switches or sensors that intelligently control the system ensuring it's operating when needed, and can also boost during high humidity level, when necessary like when taking a shower. These include humidistats, passive infrared motion (PIR) sensors and boost switches.
These systems are simple to install during new builds, major refurbishments, and existing homes.
MEV systems consist of main components, the background ventilators, such as window tricke vent, ducts from the extract areas to the fan system, and the fan that controls the air speed and exhausts the air to the outside.
The MEV fan unit is typically situated in a remote space, like the loft space, helping to hide the ducts and also reduce any unwanted noise within the home.
The MEV systems are designs to operate continuously, providing a constant low level of extraction, and can be boosted when necessary to provide high levels of extraction, such as during cooking, showering or bathing.
One of the major advantages of continuous MEV systems is that occupants don’t need to remember to switch the ventilation on or off when integrated with a control system.
The ductwork is routed throughout the building, so continuous MEV systems are most commonly found in new build dwellings, where this is design in from the start, as it is part of building regulations. However, these systems are often added to existing buildings during major refurbishments, where new ducts can be installed and current buildings regulations are required to be met. It can be more difficult to install these systems in existing homes, but there are a number of options, for a tailored solutions to suit your home.
