Frequently Asked Questions

What is an MVHR unit?

An MVHR unit, or Mechanical Ventilation with Heat Recovery unit, is a ventilation system that extracts stale air from wet rooms while supplying fresh filtered air to habitable rooms. It recovers heat from the extracted air to help temper the incoming fresh air.
How do I choose the right MVHR unit?

The right MVHR unit depends on the size of the property, number of rooms, required airflow rates, duct layout, installation location and project type. BPC Ventilation offers MVHR design support and technical advice to help ensure your system is correctly sized and suitable for your project.
How long does an MVHR system typically take to install?

Installation time varies depending on the property size, ductwork layout and stage of construction. New-build installations are generally more straightforward than retrofits because duct routes can be planned before walls and ceilings are finished.
What size MVHR unit do I need for my home?

The correct MVHR unit depends on the property size, required airflow rates, room layout and system resistance. BPC Ventilation offers a free design service to help select a suitable unit for your project.
How much does an MVHR system cost to buy and install?

Costs vary depending on the MVHR unit, ductwork, controls and property layout. BPC Ventilation can provide a system quotation based on your plans, while installation costs should be obtained from your chosen installer.
