Decentralised MVHR: The Smart House Ventilation System for UK Homes
Tired of damp, stale air but don't want the heat loss from an open window?
A decentralised mechanical ventilation with heat recovery (MVHR) system is the modern solution for UK homes. Unlike complex ducted systems, this is a single room ventilation approach
A through the wall heat recovery ventilation unit works simply: this wall mounted mvhr provides a constant flow of fresh, filtered air while extracting humid, stale air. The genius is in the mvhr heat exchanger, which recovers warmth that would otherwise be lost. The result is the best home ventilation system for health and energy efficiency.

FAQ
MVHR stands for Mechanical Ventilation with Heat Recovery. In simple terms, it’s a system that actively pulls stale, humid air out of your room while simultaneously bringing in fresh, filtered air from outside. The clever part is that it transfers the heat from the outgoing air to the incoming air, so you get fresh air without losing warmth.
Decentralised (or single-room) means the unit is self-contained and works for one specific room. This is the opposite of a large, complex ‘centralised’ system that requires extensive ductwork running throughout the entire house. Our decentralised units are the perfect, affordable solution for targeting problem rooms in existing UK homes without major renovation work.
Not at all. An extractor fan only pushes air out, creating negative pressure that pulls cold draughts in from cracks and gaps. A Climtec MVHR unit creates a balanced airflow, bringing in fresh air as it extracts stale air. Crucially, it also recovers heat, something no extractor fan can do.
Not necessarily. The beauty of a decentralised system is its flexibility. You can start by targeting the most problematic rooms first — typically bedrooms where you get condensation overnight, or living rooms where the family spends the most time. You can always add more units later to create a whole-house solution without the need for ducts.
