PIV Installation at Penzance Rental Property

The job
A rental property in Penzance suffering from persistent damp and condensation. Granite houses pulling moisture from the ground, combined with construction techniques and materials that predate modern vapour control, are common across South West Cornwall. Without very disruptive and costly work to the exterior walls, the options are limited.
What I did
I installed a PIV (Positive Input Ventilation), the unit pulls in fresh air from a ventilated loft, heats it slightly so it does not cool the house, and pushes moisture out - preventing damp air from settling on walls and ceilings.
On the day
The existing fire alarm circuit provided a clean and convenient supply point. The relay wiring was the key detail - ensuring the PIV shuts down on alarm activation is a safety requirement, not an optional extra. Wired in and commissioned in half a day.
