Heat Recovery Ventilation and its application in new homes as significantly grown over the last few years as the focus and improvements in airtightness are increased through Building Regulations e.g. ADL: Conservation of Fuel and Power.
ADF:2010 Means of Ventilation sets out the whole house requirements for Heat Recovery Ventilation (see table below)
In order to calculate airflow rates and find a suitable unit, you will need to know;
dwelling type number of bedrooms, floor area and number of occupants.
Choosing or specifying a Heat recovery system ismore than simply choosing the best SFP (Specific Fan Power Performance) and Heat Efficiency (e.g. 93%)
Considerations must be given to application in order that Guaranteed Installed Performance can be achieved effectively onsite - and it all starts with DESIGN.
Following these three rules will ensure you choose the correct SIZE Heat recovery unit for your dwelling. An incorrectly sized unit will introduce noise to a property as it will have to work harder to deliver the Building Regulations requirements.
