As an inspector for a local community action agency’s weatherization program, I have begun implementing ashrae 62.2-2010. One problem we are encountering is this, when installing whole house ventilation in retrofits, often homes have atmospheric hot water tanks. The atmospheric tanks are prone to backdrafting when more negative pressure is added to the home. In my opinion, this needs to be first and foremost in the minds of anyone who will be installing any ventilation in a home. The problem is generally magnified by a house that is already tight from the get-go and we will be tightening it as we perform our weatherization measures. Any installers should be aware of the drafting issues that may be caused by the addition of whole house ventilation and be prepared to take precautions to provide a healthy and safe home to their clients.
