added to the extract rate. The system provides quiet,
uninterrupted extract ventilation from the dwelling,
removing warm stale air via all of the “wet” rooms,
creating a permanent air path through the property
from the “dry” habitable rooms.
Air is usually drawn into the property through
background ventilators located in the building facades.
However if the system is being installed to solve an
incoming airborne noise issue, background ventilators
may be omitted (subject to the proven air tightness
of the dwelling). There is a boost facility on the fan
which enables the extract rates from all wet rooms to
be increased to counter increased pollutants cause by
cooking or bathing activities.
The current Building (Scotland) Regulations refers to
continuously operating mechanical extract ventilation
in accordance with the guidance in BRE (Building
Research Establishment) Digest 398, a paper based
on the former government department’s (and now
private company) own tests and recommendations,
specifically 0.5 air changes per hour throughout the
property. The Heatrae Sadia CVE ECO 2 complies
fully with the recommendations contained within this
document.
With the Government actively encouraging energy
saving and a target for all new homes to be ‘carbon
zero’ by 2016, the Heatrae Sadia CVE ECO 2 RFT
has been designed ‘future proof’. The ‘Code for
Sustainable Homes’ was updated in October 2010 to
reflect the changes to the 2010 Building Regulations.
Level 4 now requires a further 25% reduction in CO
emissions.
