MVHR Ducting & Ceiling Valves
One of the most important aspects of a well planned, low energy MVHR system is the ducting type used. Careful consideration to the design and choice of installation materials ensures your MVHR system delivers the correct ventilation rate and heat efficiency to your home.
Product Suitability
Heat Recovery Ventilation (MVHR) Rigid Ducting
The best practice is to use larger diameter, 125mm diameter branch lines and up to 250mm diameter main lines, which can carry the necessary high volumes of air at low velocity (depending on size of system).
Benefits of Rigid Ducting
Rigid, large diameter ducting is the preferred choice to provide a smooth flow of air with the least resistance, causing less noise (from both fans and air turbulence) and costs less to run. A minimum of 25mm aluminium foil backed wool insulation to ducting in a cold space is essential to retain high heat efficiency and avoid condensation forming in the ductwork.
MVHR Ceiling Valves
Visible in every habitable room, it's important that the supply and extract air ceiling valves are of high quality. Our modern Supply & Extract Valves are manufactured in high quality steel and are designed to not produce down draft, ensuring a comfortable indoor climate.
We have a range of supply and extract air ceiling valves in various sizes, including (but not limited to):
- 100mm
- 125mm
- 150mm
- 200mm
Fire Rated Ceiling Valves
Our highly cost effective Fire Rated Ceiling Valves meet the requirements of Building Regulations Document B and are easy to retro fit in place of existing valves. Available in 125mm and 150mm options.
Frequently Asked Questions
Here are some of the most frequently asked questions about our MVHR systems.
How does a Mechanical Ventilation with Heat Recovery (MVHR) System work?
Fresh air is continuously drawn into the home via a low energy ventilation unit, located in the roof/space/utility area of your home. The ventilation unit filters the incoming air to remove pollutants and insects. Once passed through the heat exchanger within the power unit, the warm, fresh filtered air is distributed around the home through a series of ducts which are run to each habitable room ie. living room, bedroom etc.
The air from wet rooms i.e bathrooms, kitchens, wc’s, utility areas etc is continuously extracted and filtered back through the ventilation unit. The heat from the extracted air is transferred to the fresh incoming air.
How do I ensure compliance with current building regulations?
Beam Heat Recovery Ventilation Systems have been independently tested at the Building Research Establishment (BRE). The Axco ventilation power units are SAP Appendix Q listed and comply with all building regulations and help improve SAP / BER ratings. it is required by Building Control to have the ventilation system commissioned, a service provided as standard for all installations by Beam Vacuum & Ventilation.
When should I plans for it to be installed?
Planning is key. A ventilation strategy plays a critical part in building today's modern home. It is good practice to plan your ventilation strategy during the planning stage of building to ensure the location of ducting and the unit can be considered during the build process.
Will the indoor air quality in my home be improved?
Studies show there is a direct connection between the quality of air (caused by poor ventilation) and our ability to concentrate and perform productively, as well as the effect poor indoor air quality has on asthma or allergy sufferers. The ventilation unit filters the incoming air to remove pollutants and insects and the constant supply of clean, fresh, warm filtered air reduces symptoms for asthma and allergy sufferers.
