Mechanical Ventilation with Heat Recovery (MVHR)

MVHR has become a norm in new build properties, especially now developers are looking to ensure their houses are air tight, and meeting new
SAP energy requirements, it is also a great choice for self-builders, another way to ensure your house is energy efficient. With these new technologies. Where do you start? Firstly why is it needed and what is involved, and how is it going to fit within the design of the property?

What does MVHR do and why is it needed?

MVHR replaces natural ventilation within the home, where traditionally this would have been through an airbrick, and more currently through trickle vents in your windows. Now we are looking to ensure your home is the most energy efficient, closing thermal bridging spots, highly insulating properties, installing low U value windows and losing trickle vents, we need to add in a mechanical ventilation system to provide ventilation without losing heat. The Mechanical ventilation with heat recovery system, does just that, it provides heat recovery whilst providing ventilation, so how does it do this?

We gain heat from extract areas that would normally be wasted, extract air from Bathrooms and Kitchens, this air contains warm humid air, and is transferred via a heat exchanger, where fresh air is also transferred, warming constant fresh air into the property. And another added bonus, the filtered fresh air from your mechanical system, is great for allergy and asthma sufferers. But for all this to work at its optimum, to ensure there are no condensation build ups within your home and to ensure a quiet system, it must be a well thought out and designed plan, and that’s what we have learnt to do… and are now proud to say we can…

What we provide:

  • Provide advice on suitable MVHR system, building regs, controls and installation
  • Discuss system and layout with yourselves before design if necessary to ensure we have a clear understanding of the project.
  • Produce an MVHR ductwork layout, either radial ducting or branch rigid ducting to suit building construction and best practice guidelines
  • Ideally site unit in optimum position
  • Create a Bill of materials containing all ductwork, controls and units

What we need:

  • PDF or CAD plans
  • Unit position, if you have one in mind
  • Joist Type and depth, if necessary
  • Ceiling void depth
  • Steel beam locations
  • Atmosphere termination positions (we can advise on this if required)
  • Electrical & lighting layout
