As independent specialists BPC Ventilation can design and supply the largest range of commercial heat recovery systems to suit any size, budget or specification from economical cost-efficient units to bespoke handmade units for specialist applications.

Our Commercial MVHR units are used in all kinds of application, from offices and hair salons to schools, shops, hotels, hospitals, public rooms and retail establishments.

Why MVHR?

The indoor climate is of the utmost importance in work places as most of us spend the greater part of our working lives indoors.

"To ensure comfort and a sense of well-being, the air we breathe must be clean, at the right temperature and right humidity levels."

Whatever the situation, Mechanical Ventilation with Heat Recovery (MVHR) solutions can play a significant role because they help create a healthier living and working environment, while contributing to the reduction of a building's carbon emissions and energy usage.

Heat recovery systems are very popular with school classrooms and offices by keeping Co2 levels below 1000 and filtering the air to below PM2.5 providing the ideal environment for optimal concentration and awareness.

BENEFITS OF COMMERCIAL HEAT RECOVERY:

  • Improves indoor air quality
  • Co2 levels kept down reducing fatigue and tiredness
  • Prevents mould and condensation
  • Recovery of normally lost heat during cold days
  • Controlled circulation of filtered outdoor air during warm days
  • All air is filtered reducing contaminants and pollen levels
  • Continuous fresh air reducing airborne bacteria and germs

HOW DOES IT WORK?

Heat recovery units are supply and extract systems delivering filtered fresh air into a building whilst extracting stale stagnant air from the interior.  Each unit will have a heat recovery element (either a thermal wheel or counter-flow plate heat exchanger that can transfer the heat that would otherwise be lost into the incoming air flow.

Types of units

Plate heat exchangers are up to 95% efficient and due to their low profile are ideal for application in ceiling voids or where space is at a premium.

Thermal wheels are 70-90% efficient and are often used on larger duties like swimming pools and factories where replacing heat losses can be expensive. 

Run-around coil exchangers are used when you need to extract the heat from an exhaust airstream which may be dirty or contaminated, such as extract from a commercial kitchen. In this instance the run-around coil uses water in the exhaust airstream coil to absorb exhaust heat energy which is then pumped to a coil positioned in the supply airstream where heat is transferred.

When needed, a commercial heat recovery system can be adapted to incorporate cooling, heating, additional filtration and sophisticated control packages. 

Technical Support

"We are Independent and here to help you"

Our in-house Technical Team can assist with helping you choose the right commercial MVHR system for you.

Design and specification

BPC can help design and specify a heat recovery system on small and medium sized projects, On Large or complex systems we can work with your consultant and technical designer to choose a suitable system that fits within your budget.   

Cost

BPC have one of the largest ranges of commercial MVHR units available that include units suitable for offices of 20 people at below £1,000 (excluding ducting) to complex demand-controlled systems with cooling and heating at over £10,000.

Because commercial buildings use more power generally than domestic premises, businesses have the potential to benefit more from commercial heat recovery. A simple plus for offices that have a suitable ventilation system installed is that they can provide clean, fresh air for their employees but also cut down on energy bills with efficiency savings.

The Return on Investment for Commercial Heat Recovery

Whilst most new builds now incorporate a full commercial heat recovery system that automatically reduces the costs and provides a more sustainable environment, older buildings have greater challenges to overcome. The need for a bespoke solution for older buildings is often a matter of the space available to undertake the retrofit. Retrofitting an existing office block or commercial premises comes at a cost but the payback could be quick if the right system is installed.

Environmental

Businesses nowadays must take their carbon footprint seriously and a commercial heat recovery system, combined with other green strategies, can greatly decrease carbon emissions and take a chunk out of the price they pay for electricity and heating bills.

Retrofitting

In most cases some form of heat recovery systems can be retrofitted but as with domestic MVHR systems there are several issues to consider before considering a heat recovery system.

  • Is their space on the premises for a commercial heat recovery system? That’s not just for the ventilation unit but the ducting that must connect each of the rooms in the building.
  • Is the new system simply replacing the old one or does a whole new infrastructure need to be installed?
  • Can you integrate the new heat recovery unit with your existing systems?
  • Cost - In most cases it is less expensive to install when the building is being built or renovated.

Controllability

Heat recovery units come with a large range of optional control system 

  • No control – Simply has a on and off switch to control system
  • Demand Controlled- uses Co2 sensors that increase speed and performance according to how many people are in the room
  • Humidity sensor- To increase speed when humidity rises as in a swimming pool or shower area
  • PIR – A simple inferred sensor to increase speed when someone is present
  • BMS- Building management interface allowing the unit to be controlled remotely or in plant room
  • KNX – More domesticated system with mobile Applications
  • Digital control panel – a Simple to operate and independent wall mounted control panel
  • TREND- is a Building Energy Management System that can incorporate HVAC and electrical systems
  • Constant pressure control – maintains system performance when more resistance has occurred.
