MUA Tempering
Does make-up air need to be heated?
Pre-Heating Intake Air
In Alberta, bringing in -30°C air directly to the kitchen can cause discomfort and pipe freezing. We recommend an "inline heater" for the MUA duct to temper the air to at least 10°C before it enters the living space.
Central Alberta spec for pre-heating incoming fresh air to prevent freezing pipes and cold drafts during winter operation.
