MVHR Market Data

Introduction

• New buildings are becoming increasingly airtight
• Demand

for continuous mechanical ventilation is increasing

• Building Regulations are favouring MVHR in new homes
• 95% of Vent-Axia MVHR business specification driven
• More enquiries through electrical distribution
• Massive opportunities as housing market improves

Building Regulations

• 1992 – Ventilation was first introduced into Building Regs.
• 2006 – Ventilation systems were being installed by skilled persons but

the performance data was never recorded.

• 2010 – Ventilation systems had to be installed correctly and airflow

rates measured. More demand for mechanical ventilation with heat recovery.

• 2016 – Mechanical ventilation with heat recovery the most likely
• choice. Buildings require a significant reduction in carbon emissions.

Building Regulations

Four key areas the Building Regulations are seeking to improve: 1) Installed airflow performance 2) Energy efficiency 3) Good quality installation 4) Ease of use by home occupier

Types of ventilation

• System

1 – Background ventilation and intermittent extract systems (including cooker hoods)

• System 2 – Passive stack ventilation
• System 3 – Continuous mechanical extract (MEV/dMEV)
• System 4 – Continuous mechanical supply and extract

with heat recovery (MVHR)

What is MEV/dMEV?

• Extract stale air from wet rooms
• Fresh air supplied in through background (trickle) vents

Issues with MEV/dMEV?

• Loss of heat from the dwelling
• No filtration of air into the property
• Noise control

What is MVHR?

• Unit is centrally located – normally in a loft or cupboard
• Extract and input vents are connected to the central unit using rigid ducting
• Air is extracted from wet rooms – bathrooms, kitchens etc

System 3 – MEV

What is MVHR?

• Fresh filtered air is supplied into other habitable rooms – living rooms, bedrooms,

dining rooms

• The extracted air is passed over a heat exchanger in the MVHR unit. The heat in

the extracted air is removed and used to heat incoming air

System 4 – MVHR

How does MVHR work?

• The unit incorporates a heat exchanger

that tempers the incoming air before it is delivered to the habitable rooms.

How does MVHR work?

Energy Saving – why heat twice?

What does this mean for you

• With demand increasing for MHVR more

contractors are getting involved with the installation.

• However the supply chain has widened and

it is essential to make sure you achieve your fair share.

• There are many advantages of increasing

your turnover in this sector.

What does this mean for you

• With the units making up part of a whole

house system the transactional value is much higher.

• Giving you a larger cash margin per job and

subsequently helping you achieve your targets much quicker.

• This in turn helps you achieve your rebate

bands sooner and further increasing your

• verall profits.

How can we help?

• Free design service
• Joint site visits to utilise our expert sales force to

ensure better conversion rate

• In branch training given to staff and aim to allocate

a ventilation champion with CDP certificates added and on line material,

• Installer BPEC training programme done in

conjunction with your branches

• On Line Fan selector

CPD Training

• How do you access Vent-Axia CPD’s?

We come to you: Simply choose the subject you require and a Vent- Axia specialist will arrange a seminar to be delivered at your premises. This normally takes place during a lunch hour or after working hours thus not taking up too much of the working day.

• Following the seminar each delegate will receive a

certificate for 1 hour CPD for their records
