Children learn better when they can breathe properly. This is not a theory — it is one of the most consistently documented findings in educational building research. CO₂ levels in a sealed classroom rise rapidly once children are seated and working. By mid-morning, concentrations in a typical teaching space can reach two to three times the level considered safe for sustained concentration. The result is not laziness or lack of engagement — it is a physiological response to air that has quietly stopped supporting the brain’s ability to focus.

CodeNinja runs coding classes for children across London — structured, hands-on sessions that demand exactly the kind of sustained attention that poor air quality is most effective at undermining. The teaching space had no adequate mechanical ventilation system: windows provided some airflow in warmer months, but during the school year, with the room sealed and occupied, indoor air quality deteriorated quickly and noticeably.

The Solution: Decentralised MVHR

A Prana decentralised MVHR unit was installed directly through the external wall of the teaching space — a single core penetration, no ductwork, no suspended ceiling works, no disruption to the room’s decoration or layout. The single room heat recovery ventilation system continuously draws stale, CO₂-rich air out of the classroom and replaces it with fresh air from outside, recovering up to 96% of the room’s heat through a copper heat exchanger in the process.

For a children’s education setting, the copper element carries particular value. Copper is a natural antimicrobial material — actively reducing bacteria and airborne pathogens in the air passing through the MVHR unit. In a room where children share equipment, sit in close proximity, and spend concentrated time together, this is a meaningful and practical benefit.

The MVHR system operates silently throughout each session — below the threshold of distraction, running continuously in the background without requiring any adjustment by teaching staff. Built-in CO₂ and humidity sensors monitor the classroom air automatically, increasing ventilation rate when occupancy rises and stepping back when the room is empty. The entire heat recovery ventilation system is manageable via smartphone, giving the venue full control without complexity.

Installation MVHR unit: Before the start of the semester

The decentralized installation of the MVHR system was completed in one day during a break between classes. The hole in the external wall was drilled, the coupling and the heat recovery ventilation unit were installed, the external grille was installed, the room was left clean. No plastering. No painting. No further construction work.

Why MVHR System Matters for Children

Fresh air in a learning environment is a performance condition. Research consistently links elevated indoor CO₂ with slower information processing, and shorter attention spans. For children attending after-school coding classes who are already managing a full day of concentration, the air quality of the room they walk into matters more than most providers realise.

Since the Prana MVHR unit was fitted at CodeNinja, the teaching space maintains consistent, fresh room ventilation throughout every session — regardless of how many children are present, how long the class runs, or whether the windows are open. CO₂ levels remain within the range that supports active learning. The air is clean, dry, and continuously renewed.

MVHR for Education and Commercial Premises Across the UK

Children’s classes, tutoring centres, nurseries, and after-school clubs share a common challenge: small rooms, high occupancy, limited ventilation, and the need for a solution that does not require construction works or ongoing management. Decentralised MVHR systems address all of these conditions precisely — room by room, installed quickly, running quietly, delivering measurable results.
