Heat Recovery System Installation Options

A Heat Recovery System (MVHR) is an excellent way to improve indoor air quality and energy efficiency in your home or business. When it comes to installation, you have two main options: installing it yourself or by BEAM's team of experienced installation engineers or BEAM Approved Distributor Partners.

MVHR Installation by BEAM

Opting for an MVHR installation from BEAM and our network of approved partners is a hassle-free way to ensure that your system is designed, installed, and commissioned to meet the highest standards. Our team of expert MVHR installers provide a seamless service that guarantees efficiency, durability, and long-term reliability.

DIY (self) MVHR Installation

For those who prefer a hands-on approach, BEAM offers a DIY MVHR installation option. This allows property owners to install their own system while still benefiting from our detailed design, expert guidance, high quality materials, and certified commissioning service.

Bespoke MVHR System Design

Before installation can begin, the MVHR system needs to be designed. Whether you choose to have your system installed by BEAM's expert engineers or a DIY approach, we provide professional MVHR system design to ensure complete compliance with building control ventilation requirements. We recommend planning your ventilation strategy early in the build, along with other services and lighting designs.

Tailored to Your Property

Our team of specialists will design a customised MVHR System tailored to suit your home or business, which ensures optimal performance and maximum efficiency. 

Our expert design will determine:

  • Unit location
  • Ducting layout
  • Supply & extract valve placements

What stage of the build is MVHR installed?

Whether your property is a block build or timberframe, it's important to know what stage of build a BEAM MVHR system needs to be installed.

Before Installation

After an MVHR system has been designed to suit your property, it is very important to agree final valve locations, and routes & duct locations prior to the installation start, in conjunction with other services and/or lighting design. Placement of intake and exhaust positions should also be determined prior to installation.

During the build - Preparations

2 Plenum boxes (supply & exhaust external terminations) are to be placed in the gavel walls whilst being built, or 2-4 roof cowls are to be fitted onto the roof depending on MVHR model type. The plenum boxes or roof cowls will be supplied by BEAM but it is the responsibility of the owner/builder to install them. 

If the MVHR unit is being located in the roofspace, it’s important the access hatch is large enough for the unit to fit through now & for future requirements.

MVHR Ducting Installation

Ducting is installed when the building is watertight, i.e the roof is on, windows are in and external doors are fitted. In block builds, ducting should be installed before other services are fitted below the concrete slab. A 150mm void below the concrete slab will allow ducting to be installed. A void of 100mm will mean you will have to convert to 204/60mm flat channel ducting. In timberframe builds, timber partition walls and floors must be in place and MVHR ducting should be installed before other services.

After plastering & floors complete

New builds absorb a lot of moisture during construction - keeping the heating system on and windows open will help to dry the house out. You may also use a dehumidifier. Your system can now be tested for airflow rates and system balancing. Handover & start up can only happen when the house is properly dried out.

  • Please ensure 8-10mm gap under doors to facilitate adequate air movement throughout property
