When to Install a Heat Recovery Ventilation (MVHR) System 


Whether our team of MVHR installers are professionally installing your system, or we supply a DIY MVHR system to you, installation should take place as follows:

Firstly, at design stage - plan for your ventilation systemBeam MVHR ducting in roofspace


A well designed ventilation system is critical and should be incorporated into the drawings at as early a stage as possible. A ventilation strategy is essential for every new home and should be implemented alongside all other primary services. This is something which should be discussed at design stage. 

If you are interested in MVHR for your new home, we recommend sending in your plans for a free quotation just after the design stage, when you receive planning permission.

House with roof on

Block-build

  • MVHR installation begins when the building is watertight 
  • This is when the roof is complete, windows and external doors are in
  • A void space of between 100mm - 150mm below the concrete slab must be factored in to incorporate the duct system for the ground floor
  • Ducting should be laid before any other services are installed below the concrete slab
  • Ducting should be installed before the metal grid/ timber baton ceiling is erected

Timber-frame construction

  • MVHR installation begins when the building is watertight 
  • This is when the roof is complete, windows and external doors are in
  • Timber partition walls and floors must be in place
  • Ducting should be laid before any other services are installed


Best Practice MVHR Installation

All systems are designed in-house by our experienced technical team and installed by our own team of BPEC registered mvhr installers.

Our Mechanical Ventilation with Heat Recovery (MVHR) systems are installed with smoothflow rigid ducting throughout, providing higher heat efficiency. The resulting low pressure loss will mean a lower energy use and the system will be quieter due to efficient low velocity.

This solid ducting is resistant to crush damage during the construction phase

We only use precision engineered metal and plastic fittings, ducting and silencers mechanically fastened and sealed at every joint.
 

Cost of MVHR Installation

All our systems are bespoke to your house requirements, and the cost of MVHR installation is dependent on a number of factors. To get a free no-obligation quotation, please contact us.

Should you decide to install a MVHR system from Beam on a DIY basis, we can provide design layout and commissioning.
It is crucial that best practice is adhered to at all times to ensure system efficiency.
