Positive Input Ventilation System Installation PIV | Shoreditch | London | E1


Positive Input Ventilation System PIV | Shoreditch | London | E1

Leigh Electrical Contractors were called by a family in Shoreditch, London that was carrying out a full refurbishment of their Victorian terrace house. The house was 3 flats and was being turned into a large family house, when the survey was carried out before the purchase it came back with serious mould problems in each flat.

The mould problem was exceptionally bad in the basement that was being mainly caused by the damp coming through the walls. When Leigh Electrical Contractors carried out the site survey the smell of mould in the basement was very over powering. The top 2 flats also had a lot of condensation that had started to turn into black mould but this could easily be fixed with the addition of a correct ventilation system.

As the flats were now going to be one house Leigh Electrical Contractors recommended to install an Envirovent PIV in the loft and also an Envirovent wall mounted PIV in the basement, as the filtered air from the loft PIV wouldn’t be able to reach the basement as it was too far down.

The basement was being tanked in plastic by a damp company, they were also knocking the plaster back to brick so that it could be re-rendered in a waterproof plaster. The ceiling was also taken down so that it could be insulated which meant that we could run the 4″ pipework through the ceiling and out into the garden.

This 4″ pipework brings fresh air into the Envirovent wall mounted PIV which is then filtered and then circulated around the basement. The Envirovent loft PIV works in the same way but instead of needing an air source from outside the Envirovent loft PIV filters the dryer air from the loft.

A PIV unit are the easiest and cheapest way to combat condensation and provide a healthier indoor air quality by filtering the air in the loft and providing a constant flow through the house. This dry flowing air stops the water vapour sitting on the windows and walls and turning into water droplets leading to condensation.

The problem areas in any property are the places where there is higher levels of humidity in the air like the bathroom and around the windows in the bedrooms. The outside walls are also a problem area as the walls are cold and where the warm humid air hits the walls it turns in to water droplets and is sucked into the plaster causing damp patches.

Without tackling condensation mould will keep coming back in your property unless you deal with the root cause of the condensation and tackle the humidity in the air. If nothing is done about the mould it can not just affect the property but also the health of the family, this can be even more dangerous to the elderly and the young.

As well as the Envirovent loft and wall mounted PIV an Envirovent in-line fan was added to the main bathroom and a Envirovent trickle fan was added to the downstairs toilet as well as a powerful kitchen extractor above the hob.

The ventilation system was installed along side the refurbishment work and Leigh Electrical Contractors also carried out a full rewire of the property and worked side by side the other trades.

The family have now moved into the property and on a recent revisit they were happy to tell us that the condensation problem had stopped and there was now no black mould anywhere in the property. They also told us that the air in the house seemed a lot fresher and the smell of mould had completely gone from the basement.
