Mechanical Ventilation & Heat Recovery

What is Heat Recovery?
Heat Recovery works by recovering the heat in the air being lost through fresh air vents, instead the heat is exchanged using a MVHR unit. The system works by supplying fresh air to rooms in your home or business premises while extracting moisture and heat from wet areas such as toilets and kitchen spaces. Warm stale air is removed from the building through grilles and ductwork; it is then passed through a heat exchanger which transfers some of its heat to the colder incoming fresh air. Airwave Technology supply and fit  the latest heat recovery systems available.

In the UK & Ireland building regulations have been made considerably stricter over the past decade. That has in particular been brought about by care for our environment (CO2 emission) and the need to cut back on the use of fossil fuels. As far as residential building is concerned, this has resulted in strict insulation standards.After all, in a tightly sealed home considerably less energy is used than in a dwelling from the seventies or earlier. However, this does have its drawbacks. To prevent draughts, many people do not ventilate their home in winter, which causes bad air quality. Not to mention the accompanying ‘humidity problems’. Every day an average family produces some 10 litres of water vapour through showering, cooking, washing, perspiring, etc. If the rooms are not ventilated sufficiently, that has harmful consequences for the building structure as well as for the residents themselves. All in all it’s not so strange that GPs find an increasing incidence of chronic respiratory problems. The answer to both  problems is an efficient Mechanical Ventilation and Heat Recovery system. (MVHR)
The MVHR system operates by recovering the energy that would normally be lost through open windows, wall vents etc. The warm stale air that is being extracted from the building is passed through the heat exchanger to warm the fresh filtered air being brought into the house without cross- contamination. It filters the incoming air through F7 or greater rated pollen filters and also warms the air by passing through the heat exchanger.
Balanced ventilation systems with filtered supply are ideal for asthmatics or any body suffering from allergies or respiratory problems.

In general, whether you have allergies or not there are huge benefits to your health by breathing in fresh air.

De-Centralised Ventilation with Heat Recovery

The de-centralised ventilation system  with heat recovery is designed for improving the interior air quality, particularly in existing rooms. The system can simply be retrofitted and fully automatically controls the ventilation flow rate.
Poor ventilation is often behind sick building syndrome, which is known to cause symptoms including eye, nose, and throat irritations; headaches; fatigue; difficulty breathing; itching; and dry, irritated skin. Through moisture management, pollutant source control and adequate ventilation rates, green schools have cleaner air and thus a healthier environment more conducive to learning.

A Swedish study has shown that asthma and asthmatic attacks can be signifantly reduced by proper ventilation. Studies have repeatedly shown that ventilation in schools is inadequate, with carbon dioxide concentrations in the air often reaching unhealthy levels. This affects students’ ability to concentrate. Ventilation concepts are therefore one of the top concerns in the energy-oriented refurbishment of schools.

Germs thrive in stuffy, unventilated environments and spread through the air via sneezes, coughs and colds. With the growing concern over the recent MRSA, C diff (clostridium difficilie), Vomitting Bug  and flu epidemic scares, tougher measures in areas such as decontamination and cleanliness are being implemented. With the majority of germs passed on from person to person through close contact and airborne particles, doctors waiting surgeries are prime targets for infections to be carried and passed on.
Creating the perfect indoor environment with good indoor air quality not only reduces allergy and asthma symptoms but also provides a pleasant and calm atmosphere that will help relax patients and can even boost productivity for staff by reducing fatigue this is all made possible by installing a de-centralised heat recovery unit.
