MVHR Radial Ducting and list of parts in the DIY Kits

Following years of heat recovery design and installation BPC Ventilation are now able to provide high quality kits that will provide a quiet and efficient system exceeding building control regulations and are suitable for any competent person to successfully install

The Quiet-Vent radial semi rigid system combines the performance benefits of rigid duct and the installation benefits of flexible duct by treating each room individually with a dedicated 75mm duct run from two manifolds (distribution box) for supply and extract air at the heat recovery unit

Quiet-Vent Semi Rigid Duct is a perfect choice for MVHR Heat Recovery System Installations as it provides huge performance benefits whilst dramatically reducing installation time and installation risk on-site

Key Features

• The pipes have a smooth bore that is hygienic, anti-static, non-porous and odourless which inhibits mould and bacteria growth with low air-flow resistance and has high sound absorption.
• The round 75mm pipe is supplied in 50-meter-long rolls and takes more than 13 Kilonewton’s per square metre of pressure to crush it and can even be buried in up to 3 metres of concrete.
• No noise transfer (talking, music etc) between rooms (As required and stated in the 2010 Domestic Ventilation Compliance Guide).
• No noise generated by high volumes of air being pushed or sucked down ducting (common with branch systems).
• No joins in ducting so it cannot become dislodged if knocked or disturbed e.g. in loft spaces.
• 70% Quicker and easier to install compared to traditional branch systems.
• Metal distribution boxes – very robust and durable, various sizes.
• Can easily overcome site obstacles and can be worked through around joists with ease
• Fully cleanable and one of the only systems on the market that is - making it ideal for Heat Recovery System installations as it offers long-term Guaranteed Installed Performance
• Superior 100% airtightness as there is up to 85% less joins and any fittings use rubber seals 
• Ideal for metal web and engineer joists
• SAP Appendix Q and Passive House Approved (classed as solid rigid on SAP)

How does a Radial system work?

Radial ducting is the latest innovation on ventilation systems and can provide a quieter and more efficient ventilation system compared to rigid ductwork.

Radial Ducting is a system of individual smooth bore pipes which are crushproof, semi flexible with zero air loss. The pipes have an anti-static and antibacterial lining which individually connects each room to a manifold

The manifold takes mass airflow directly from the MVHR Heat Recovery Unit and allows lower rates to pass through to each individual room run eliminating noise transfer and increasing the efficiency of the heat recovery unit

The radial ducting is designed to be installed below the loft insulation to provide a superior heat retention over pre-insulated solid rigid above the loft insulation

Radial semi rigid ducting is suitable for any type of property; including timber framed houses, passive house approval homes and can be used in areas with limited access.

The radial semi rigid ducting is available in both circular (75mm or 90mm) and oval (51mmx114mm) fittings.

Alternative duct options

We can also stock and supply Solid Rigid PVC, Galvanised Steel and Thermal EPP (foam) ducting if preferred

Installation Guide

Vent Axia FH 1st Fix

1. Position vent axia FH unit proverbially on a wall or vertical timber frame with provided wall bracket
2. It is possible to take pipes from either the top of side of unit
3. Duct connections RHS unit -rear left is extract from house-front left is supply air to living areas- rear right is air intake from outside - front right is air to outside
4. Install wiring for controllers (see bottom of page for further details)
5. Install condensation drain from unit to internal or external drain
6. Install wall /Soffit vents or roof vents (Minimum 1.5 meter apart) Pipes are 125mm diamater
7. Position distribution boxes in the chosen location (proverbially in a central location minimising duct lengths )
8. Install silencer (if specified) to air supply distribution box
9. Install solid rigid ductwork and between distribution boxes and MVHR unit, (If possible allow for insulated flexible ductwork for final connections of MVHR unit )
10. Install radial pipe into the distribution box ,
11. Cut to length and install pipe into ceiling plenum, (insure you install rubber seal onto pipe) secure pipe in place with fixing band or pipe clips

Warning! There can be either one or two pipes going from the distribution box to the plenum depending on the required airflow , Always check plan that will indicate 1 or 2 pipes Install insulated rigid or insulated flexible ductwork to external vents Seal all open pipes to prevent debris and moisture ingress

Vent Axia FH 2nd fix

1. Trim ceiling Plenums to height of plasterboard (Easier to do before plastering ceilings)
2. Install air valves to plenums (slightly open valve by two turns)
3. Install all controllers
4. Check that condensation drain has been fitted
5. Switch unit on and follow the set up procedures
6. Check air flow rates and commission system

Initial Design -

Pre designed plan - Please follow the plan ensuring the correct number of pipes to each area - Please note the plan is only a guide and you may have to reroute pipe work differently and reposition valves to suit layout of rooms

No Plan - If a design is not possible due to renovation, Retrofit or properties with multiple obstacles simply follow the listed recommendations

We would recommend that you

• Install 2 x pipes from the distribution box to the room air plenum if air flow requirement exceed 10 L/s or if length over 15 meters  
• Install 2 x pipes from the distribution box to the air extract plenum in the main shower rooms and Kitchen
• All other areas only require a single pipe from the distribution box to the room air plenum
• Radial ductwork is suitable to be fitted below your loft insulation providing superior heat retention Insulate any ductwork or Manifold/ Distribution boxes with a minimum of 25mm thermal duct wrap that go above insulation in unheated attic spaces
• Slim-line manifolds are suitable for installation to concrete ceilings and only require a 100mm service void
• Position supply plenums approx. 500mm from corner of wall (avoid areas above beds and wardrobes)
• Position extraction plenums to outside of showers and above kitchen sink (not cooker)
• Only extract from a room with a open appliance (stove) if there is a supply with equal or higher airflow
