Loft Mounted PIV Unit with Heater

The Newlec NL-PIVH is a loft-mounted positive input ventilation system designed to improve indoor air quality and control condensation across the whole home. Ideal for properties with a usable loft, it continually introduces clean, filtered air into living spaces, helping to dilute indoor pollutants and manage humidity to reduce mould and mildew. Typically supplying air from a central point—such as the landing in a house or the main hallway in a bungalow—the unit delivers a gentle, consistent airflow that reaches every room. By drawing on the naturally warmer loft environment, it can temper incoming air for comfort and help minimise cold spots and stale conditions that cause condensation. For added comfort in cooler weather, the NL-PIVH is available with an integral electric heater that automatically warms the supply air when needed. This feature helps maintain a pleasant indoor climate without overworking your primary heating system. With quiet, low-energy operation and straightforward maintenance, the NL-PIVH provides an unobtrusive, set-and-forget solution to year-round ventilation—reducing the need to open windows and supporting a fresher, healthier home. · · · Keep windows closed: provides fresh, filtered air without the heat loss associated with opening windows during the heating season. · · Solar gain advantage: uses naturally warmer loft air, typically around 3°C above outdoor temperature, to pre-temper supply air—helping trim heating demand (often cited as ~150 W/day in a typical home). · · Heat redistribution: introduces a gentle, near-imperceptible airflow that circulates warm air from ceiling level through the home, reducing cold spots and supporting lower space-heating costs. · · High-efficiency brushless DC motor: ultra-low watt design for minimal energy use and long, reliable service life. · · Quiet operation: engineered to run with low noise, keeping ventilation unobtrusive. · · Comfort heater with safeguards: integral heater pulses on colder days to maintain set minimum supply temperatures; includes independent safety cut-outs and a separate enable/disable control. · · Hours run meter: built-in usage monitor to verify operation and support maintenance planning. · · Reduced condensation: helps tackle damp patches, misted glazing, and wet walls by maintaining consistent airflow and humidity control. · · Helps prevent mould: supports stable relative humidity to discourage mould and mildew growth. · · 3-year warranty: dependable coverage for peace of mind
