Positive Input Ventilation Units - PIV Installation Suffolk & Essex

The Key to How to Prevent Condensation, Mould & Poor Air Quality in Homes 

Mr Misty installs positive input ventilation units (PIV) in homes in Ipswich, Suffolk and Essex, helping to improve the indoor air quality for households across East Anglia. PIV units are a convenient, simple and cost-effective way to reduce condensation dampness and mould in the home, and are one of the most popular low-energy, whole-home ventilation methods in the UK.      

PIV units are an unintrusive way to make a real difference to the air quality of even the most well-insulated, energy-efficient property. Generally installed either in the loft space, or in a hallway or utility room, the low-energy PIV unit runs constantly and quietly all year round, creating consistent, reliable ventilation all around the home. 
 

 

Why is good ventilation in a home so important? 

Poor ventilation can lead to the humid air building up moisture levels in a property. When moisture builds up faster than it can escape, this can result in condensation which can quickly turn into a much bigger issue, such as damp and mould. Poor ventilation can significantly affect not only the fabric of the building, but most importantly the air quality inside a property.

Everyone is vulnerable to the health impacts of damp and mould, but people with certain health conditions, children and older adults are at greater risk of more severe physical or mental health impacts.

The threat to health of damp and mould is considered of such importance that private and social landlords must now adhere to a number of ventilation regulations. Positive Input Ventilation units installed by Mr Misty Ipswich in Suffolk and Essex enable full compliance with Part F and L building regulations. 

How Does PIV work?

PIV works by introducing fresher, filtered air gently into a home, generally from a suitably ventilated loft. Air is first drawn into the positive input ventilation unit, then passes through filters before being  pushed around the building. 

The continuously moving air not only dilutes contaminants, but displaces - and eventually replaces - the home’s stale, humid air.

The stale air is moved out through the natural leakage points which exist in even the most well-insulated and energy-efficient home.

Natural leakage points in a home may include windows, underneath doors or even through keyholes. 

The important thing is that the PIV unit introduces the fresher air in a controlled way, without undoing the benefits of insulation or increasing the demand for heating around the home.
