Blauberg Reneo S 350 MVHR Heat Recovery Unit
The Blauberg Reneo S 350 is a heat and energy recovery air handling unit for whole home MVHR designs that need strong airflow, efficient heat recovery and a compact 160 mm duct connection.
The 2026 Reneo catalogue lists the S 350 with EC motor technology, an in-built pre-heater, low-weight construction, an available enthalpy modification and a counterflow heat exchanger with 93% heat recovery efficiency.
Catalogue identity check
The Reneo catalogue identifies the 350 model as the Reneo S 350. The catalogue data should be used for this product page because it provides the correct 350-specific airflow, duct, power, weight, sound and heat recovery figures.
High-efficiency whole home MVHR
The Reneo S 350 is designed for balanced supply and extract ventilation in residential projects where airflow, low noise and heat recovery performance all need to be considered early in the design.
It uses a counterflow heat exchanger to recover heat from outgoing extract air before it is exhausted outdoors, while the supply side delivers fresh air back into the home through the ducted MVHR system.
Whole home capacity
The catalogue maximum airflow gives the S 350 useful capacity for properly designed whole house MVHR schemes.
Counterflow recovery
The catalogue lists a counterflow heat exchanger and 93% heat recovery efficiency for the Reneo S 350.
Quiet operation data
Sound pressure is specified at point 4 in the catalogue, with full octave-band sound data included below.

M&E Installers
Clear duct, weight and acoustic data helps installers plan handling, routing, access and commissioning around the final room schedule.
Self-Builders
A strong option for self-build and low-energy homes where comfort, fresh air and heat recovery are part of the building fabric strategy.
Best suited for
Use the Reneo S 350 where the project needs a specification-ready MVHR unit with strong airflow, high heat recovery efficiency and 160 mm ductwork.
Final selection should always be confirmed by an MVHR design because suitability depends on the property layout, wet rooms, occupancy and target airflow rates.
- Whole house MVHR designs
- New build and self-build homes
- Low-energy and airtight residential projects
- Projects needing up to 114 l/s airflow
- Homes planned around 160 mm ductwork
- Designs requiring low sound pressure data
- Projects where heat recovery efficiency matters
- Applications considering an enthalpy modification
Specification and building design notes
MVHR unit choice should be confirmed against the full property ventilation design, including room layout, wet rooms, occupancy, duct routes, noise targets and commissioning access.
SAP, Part L and Part F design support
The Reneo S 350 catalogue data provides useful early-stage MVHR inputs, including airflow, power, heat recovery efficiency, sound pressure, duct size and SEC class.
These figures can support design discussions around SAP energy performance, Building Regulations Part L energy efficiency and Building Regulations Part F ventilation requirements.
Final compliance depends on the complete property design, SAP assessment, installation quality and commissioning results.
