In winter, some people choose to only heat some areas of the home – often meaning warm living areas but cold bedrooms! The HRV Heat Transfer Kit helps with this problem by using its centrifugal fans to push warmer air generated from a large heat source, i.e. a fireplace, into other areas of your home, balancing the temperature throughout. The HRV Heat Transfer Kit is compatible with our Next Gen Ventilation Systems.
SummerKit
The HRV SummerKit draws air from the southern side of your home and delivers more ventilation, more often to keep the air moving on those hot, sticky summer nights. The HRV SummerKit is an optional add-on to your HRV Ventilation System and is compatible with most models (excluding HRV Lite).
