Heating add-on Could the MVHR system help with useful top-up heat? How an electric heater battery can support airtight projects and reduce pressure on primary heating.
Use an electric heater battery for designed MVHR top-up heat
In a very airtight, low heat-loss home or project, adding an electric heater battery to the MVHR design can help temper the supply air and contribute a useful share of the space-heating demand.
When correctly sized by the ventilation and heating design, this can help create more even temperatures through the home and reduce the pressure on the primary heating system during colder months.
Blauberg S21 electric heater battery
Plug-in thyristor-controlled electric pre-heater battery for MVHR frost protection and ducted air tempering applications.
- Available for 125, 150 and 200 mm duct systems
- 0.6 kW, 1.2 kW and 1.7 kW options listed
- Includes power cable, control cable and safety thermostats
Sustainability What makes the casing material worth talking about? A clearer sustainability story around lighter, recyclable insulated casing material.
Recyclable casing material with a lighter footprint
The RENEO S 550 is built around a lighter, recyclable insulated casing material, helping the product feel more aligned with modern low-impact building specification.
For architects, consultants and self-builders, the sustainability story is not only about running efficiency. Material weight, installation handling and end-of-life thinking all matter.
The technical material behind the casing is expanded polypropylene, selected because it combines strength, insulation and recyclability in one moulded body.
A moulded lightweight casing helps reduce unnecessary material mass compared with heavier multi-layer casing constructions.
A recyclable single-material body can support clearer end-of-life thinking where suitable recycling facilities are available.
Eco note: formal embodied-carbon values should always be confirmed using project-specific documentation such as EPDs, CIBSE TM65 assessments or verified manufacturer data.
The casing contributes thermal and acoustic insulation, reducing reliance on extra separate casing layers.
Support carbon and sustainability discussions with EPDs, CIBSE TM65 assessments or verified manufacturer data where required.

What is the RENEO S 550?
The RENEO S 550 is a centralised heat recovery ventilation unit designed for large homes and residential projects.
It suits designs requiring higher capacity, balanced supply and extract ventilation, heat recovery and smart control.
Is it a good MVHR unit for a large house?
The RENEO S 550 is intended for larger residential projects where the ventilation design requires more capacity than a smaller unit can provide.
Suitability depends on room layout, wet rooms, occupancy and duct design rather than property size alone.
When would a 200 l/s MVHR unit be specified?
A 200 l/s MVHR unit may be specified when the room schedule, wet rooms, occupancy and duct layout require that level of capacity.
This makes it suitable for higher-demand residential ventilation designs when correctly specified.
Does the RENEO S 550 recover heat?
Yes. The RENEO S 550 uses a counterflow heat exchanger to recover warmth from outgoing extract air before it is exhausted outside.
The catalogue lists heat recovery of up to 93%.
Does it use 200mm MVHR duct connections?
Yes. The RENEO S 550 uses 200mm duct connections.
This makes it suitable for planned high-capacity duct routes where the ventilation design and installation space allow for larger ductwork.
Is it suitable for self-build and new build projects?
Yes, the RENEO S 550 can be suitable for self-build and new build residential projects.
A room-by-room MVHR design should confirm the required airflow, duct layout and installation approach.
Can the RENEO S 550 help reduce condensation?
MVHR can help manage humidity, stale air and everyday moisture when it is correctly designed, installed and commissioned.
It should be selected as part of a whole house ventilation strategy.
Does it include summer bypass, frost protection and humidity control?
The RENEO S 550 product data includes summer bypass and the catalogue identifies in-built pre-heater protection.
Humidity-related control and monitoring can also support moisture management when the unit is correctly designed, installed, balanced and commissioned.
Do I need a Part F MVHR design before choosing this unit?
Yes. The unit should be selected through a room-by-room ventilation design, especially where Building Regulations Part F requirements need to be checked.
The required airflow, number of wet rooms, duct layout, noise requirements and available installation space should all be checked before selection.
