{"title":"Ventilation | Extractor Fans, MVHR \u0026 Mechanical Extract Systems","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eGood ventilation is not optional — it is a requirement under Part F of the Building Regulations for all new builds and most notifiable renovation work. Poor indoor air quality contributes to condensation, mould growth, respiratory problems, and elevated pollutant levels from everyday activities including cooking, bathing, and off-gassing from building materials. A correctly specified ventilation system addresses all of these while recovering heat that would otherwise be lost, keeping energy consumption in check.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eTypes of ventilation in this collection\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eVentilation products broadly split into four strategies, each suited to different property types and occupancy patterns:\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eIntermittent extract fans (dMEV — axial and centrifugal)\u003c\/strong\u003e are the most common choice for individual wet rooms — bathrooms, shower rooms, utility rooms, and WCs. They run continuously at a low background rate and boost automatically on humidity or occupancy, satisfying Part F extract rates without requiring whole-house ducting. Centrifugal fans are preferred where longer or more restrictive duct runs are involved, as they maintain performance against higher static pressure than axial units.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eMechanical Extract Ventilation (MEV)\u003c\/strong\u003e centralises extraction from multiple wet rooms into a single continuously running unit, which vents to outside via a single duct. MEV is common in new-build flats and houses where running separate fans to each wet room is impractical, and where a single, serviceable unit is preferred. Units in this range scale from small residential applications up to larger multi-room configurations.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eMechanical Ventilation with Heat Recovery (MVHR)\u003c\/strong\u003e is the highest-performance option and is increasingly specified in new builds and deep retrofits aiming for low energy use. Two fans handle two separate airstreams — extracting stale air from wet rooms and supply rooms while drawing in fresh outside air — passing both through a heat exchanger that recovers up to 90–95% of the heat from outgoing air before it is exhausted. This means the incoming fresh air arrives pre-warmed, reducing the heating load on the property significantly. MVHR is the standard ventilation strategy in Passivhaus and fabric-first new builds, and is also well suited to airtight retrofits where trickle ventilation through windows is inadequate.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003ePositive Input Ventilation (PIV)\u003c\/strong\u003e supplies a continuous stream of filtered, slightly pressurised air into the property — typically from a loft-mounted unit — diluting and displacing stale air and condensation without extracting. PIV is a low-cost retrofit solution particularly effective at tackling persistent condensation and mould in existing stock where installing extract ducting is not practical.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eProducts in this collection\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eOur ventilation range is currently led by \u003cstrong\u003eVectaire\u003c\/strong\u003e, a UK manufacturer based in High Wycombe with over three decades of experience designing energy-efficient ventilation for residential and commercial applications.

For new dwellings, the ventilation strategy — whether intermittent extract, MEV, MVHR, or PIV — must be stated in the SAP calculation and demonstrated to meet the design air permeability target. For dwellings with an air permeability below 5 m³\/h\/m², background ventilators alone are insufficient and a mechanical strategy is required. Commissioning records are required for notifiable work; for MVHR systems, these should confirm measured airflow rates at each terminal against design values.\u003c\/p\u003e","products":[{"product_id":"vectaire-midi-mvhr-whole-house-ventilation-with-heat-recovery-unit","title":"Vectaire Midi MVHR Whole House Ventilation with Heat Recovery Unit","description":"\u003cdiv style=\"font-size: 16px; font-family: Georgia, 'Times New Roman', serif; color: #1a1a1a; max-width: 900px; margin: 0 auto; line-height: 1.7;\"\u003e\n\u003c!-- Intro --\u003e\n\u003cp style=\"font-size: 1.08em; margin-bottom: 1.4em;\"\u003eThe \u003cstrong\u003eVectaire Midi\u003c\/strong\u003e is a \u003cstrong\u003ewhole-house mechanical ventilation with heat recovery (MVHR)\u003c\/strong\u003e unit engineered for residential properties up to \u003cstrong\u003e170 m²\u003c\/strong\u003e.
