This High Efficiency whole
dwelling heat recovery unit is ideal for retro-fit and all
new build dwellings – especially those being built to a
higher standard of air-tightness.
Available in 4
variations:
APWD: For
apartment/half house, wired controller
APRF: For apartment/half house, wireless controller
WHWD: For
whole house, wired controller
WHRF: Foe whole house, wireless controller
The IECO4 is a high efficiency heat
recovery unit. It has a sophisticated counter-flow heat
exchanger which can recover up to 91% of the heat from the
discharge air. This recovered heat is used to pre-heat the
fresh air being brought in from outside.
- Up to 91% Heat Recovery
- SAP Appendix Q Rated
- Ultra-low 25kg weight
- Inlet/Exhaust Capacity 225 - 325m3/h
@ 150Pa
- Integrated Frost Protection
- Suitable for mounting in a loft,
storage cupboard or airing cupboard
Ventilation is necessary to maintain a healthy and
comfortable internal environment and to rapidly remove
pollutants such as moisture, volatile organic compounds
(VOC’s), allergens such as dust, oxides of nitrogen, carbon
monoxide, carbon dioxide, tobacco smoke and unpleasant
odours.
Moisture is generally assumed to be the most significant
of these pollutants because of the high rates of generation
from cooking, bathing, washing, drying etc and the
consequential condensation and mould growth problems. It
follows that if the ventilation strategy is based on
controlling this principle pollutant by heat recovery input
/ extract ventilation then logically the other indoor
pollutants will also be adequately controlled.
Stale air, and air which is hot or humid, should be
replaced at a reasonable rate.
Good ventilation means providing a balance between energy
efficient and healthy indoor air best summed up by the
catchphrase ‘Build tight – ventilate right’.
The fresh air supply rate should not normally fall below
5 to 8 l/s per occupant. This is best achieved by creating
continuous air changes of 0.5 to 1.0 every hour, throughout
the entire dwelling as specified in D.E.T.R. Good Practice
Note 268.
Although Building Regulations relate to new buildings,
the guidance on ventilation is applicable to existing
dwellings and, most important of all, the regulations are
concerned with minimising the risk to health from the build
up of pollutants. KHRVIECO4 helps to satisfy all of these
criteria.
