PIV Installation for Condensation in Bath and Bristol
TPS installs loft-mounted Positive Input Ventilation (PIV) systems in Bath, Bristol and the surrounding area. Where suitable, PIV can help reduce indoor humidity and condensation by introducing filtered air into the home. The cause of the moisture problem and the property’s ventilation should be considered before choosing a unit.
What can PIV help with?
Condensation forms when moist air meets a cold surface. PIV can help manage the humidity that contributes to this, but it does not repair a leaking roof or pipe, stop water coming through a basement wall or treat rising damp. Persistent damp patches need their cause investigated.
PIV is not a promise that every condensation or mould problem will disappear. Moisture from everyday activities, heating, cold surfaces and existing kitchen or bathroom extraction also matter.
How a PIV system works
A loft-mounted unit draws air through filters and supplies it through a ceiling air outlet, known as a diffuser. This encourages air movement through the home and helps replace humid indoor air. Suitability and settings depend on the property and the manufacturer’s installation requirements.
Is your property suitable?
TPS’s PIV service is for loft installations. We do not install basement or wall-mounted PIV units. A usable loft, suitable access, the ceiling outlet location and the proposed electrical connection need to be checked before installation is agreed.
Tell us about the rooms affected, when condensation occurs, existing ventilation and any known leaks. A photograph can help explain the symptoms, but it cannot establish on its own whether PIV is the right response.
Preparing for installation and disruption
Agree what needs clearing around the loft hatch and proposed ceiling outlet. Mention restricted access or stored items that may affect the work. Confirm who will arrange the electrical connection and whether any making good or decoration is included.
Fitting the ceiling outlet and unit can involve drilling, some dust and access through the house. Installation time depends on the property and agreed work, so confirm the programme for your home rather than relying on a fixed time estimate.
Running costs and aftercare
Running costs depend on the unit, settings, electricity tariff and whether a fitted heater is used. A heater can increase electricity use; there is no single running-cost figure for every installation.
Follow the installed unit’s instructions for operation, filter checks and replacement. Keep the ceiling outlet clear and retain the model details and maintenance information. Filter intervals vary by product and conditions, so use the guidance for your unit. Continue addressing other identified moisture sources and ventilation needs.
