Is this complete MVHR kit right for my home?

This kit is intended as a practical starting point for a typical 18-room home around 320 m². Every property is different, and final requirements can change with occupancy, room use, duct routes and the building layout. If your project is unusual or you want confirmation before ordering, send BPC your plans for a ventilation design check.

Why choose a complete BPC MVHR kit?

The kit remains fully itemised in the basket, making the individual components clear for ordering, fulfilment and future maintenance.

Frequently Asked Questions

What is a single room MVHR unit?

A single room MVHR unit is a compact heat recovery ventilation unit designed to ventilate one room or a specific area. It helps extract stale air while bringing in fresh air and recovering heat from the outgoing air.
Where can single room MVHR units be used?

Single room MVHR units are often used in retrofit projects, apartments, extensions, bedrooms, living spaces and other areas where targeted ventilation is required.
Do single room MVHR units need ductwork?

Most single room MVHR units do not require a full ductwork system. They are usually installed through an external wall, although installation requirements vary by product.
How noisy are single room MVHR units?

Noise levels vary by model and operating speed. Correct sizing and installation help keep operating noise low, particularly when the unit can run at lower background speeds.
Can multiple single room MVHR units be linked together in one property?

Some single-room MVHR systems support paired or synchronised operation, while others operate independently. Always check the compatibility and control options of the specific model.
