Gases, toxins and pollutants can cause concern in poorly ventilated buildings. Examples of toxic substances from include:
Heat Recovery Ventilation allows the building to regulate its fresh air supply and discharge stale air and toxic gasess whilst maintaining a high indoor comfort level. For example: If using a window to ventilate your home, you are losing 100% of the energy contained in that air that escapes through your window. If you use HRV system instead, up to 90% of the energy (heat) can be captured and transferred to the fresh air supply in your home. Capturing this thermal greatly reduces your heating needs that would be otherwise required to warm your fresh air.
As homes become better insulated and more airtight the risk of mould, mildew and decay increases. Unlike in old buildings, condensation existing as water vapour exits through building elements rather than as an air leak. This means moisture can be pushed into your walls, roof and floor leading to moisture problems. Moisture problems in buildings are a serious concern. Household activities often introduce more water to the indoor environment, for example clothes drying, washing, cooking and showering. This moisture must be controlled. Heat Recovery Ventilation helps regulate indoor relative humidity and allows the discharge of stale air, reducing impact of mould, mildew and condensation.
A decentralised system such as the LUNOS e2 and ego are ductless systems making them easy to install. This means they are perfect for retrofit and buildings that do not have space to install a centralised ducting system. For a new build or existing home with ample access to a roof or floor cavity, centralised systems can make sense - find out more here.
MHRV removes the homes polluted moisture laden air to the outside while at the same time replacing it with fresh air from outside by passing it through the Heat Exchanger and returning up to 93% of the energy (heat) back into your home. Modern homes are air tight and well insulated so home owners must ventilate the home to remove polluted air and toxins to ensure a healthy living home. You can open up your doors and windows and lose your paid for heating or you can invest in MHRV.
