If you're looking to improve the air quality in your home, you've probably come across single-room heat recovery systems.
This guide breaks down what they are, how they work, and when they’re the right choice for your home.
What is single room heat recovery
A single room heat recovery (SRHR) unit is a compact ventilation system that serves one room at a time. It is typically installed through an external wall and works by extracting stale air while bringing in fresh air from outside.
The key feature is the heat recovery process. Warm air leaving the room passes through a heat exchanger, transferring its heat to the incoming fresh air. This means you get ventilation without losing the warmth you have already paid for.
These units are commonly used in bedrooms, bathrooms, kitchens and home offices where ventilation is needed most.

How does Single Room Heat Recovery Work?
- Stale, warm air is extracted from the room
- Fresh, cooler air is drawn in from outside
- Inside the unit, heat from the outgoing air is transferred to the incoming air
- The room receives pre-warmed, filtered fresh air
This process ensures continuous ventilation without the typical heat loss you’d get from opening windows.
When do I need single room heat recovery?
Single Room Heat Recovery units are ideal when you want to improve ventilation and save energy in a specific room or small area like a bathroom, kitchen, or utility room, without the complexity or cost of a whole-house system.
Choose single room heat recovery if:
- You need better air quality and humidity control in one or two rooms
- Your home doesn’t have ductwork or space for a whole-house system
- You want a simple, cost-effective way to reduce condensation and stale air
- You’re upgrading ventilation in an existing building without major renovations
