Why this unit
Most systems make you choose: ducted air or warm floors. The 3D does both from one compact cabinet, forced-air heating and cooling plus a hydronic loop for radiant floor zones.
Compared with an ordinary furnace and air conditioner it can cut energy use by up to 70%, and it frees the mechanical room space a separate boiler would eat.
Best for: Homes with radiant floor heat, or plans for it, plus normal ductwork.
- Forced air plus hydronic radiant floor from one unit
- Compact footprint for tight mechanical rooms
- Up to 70% energy savings vs a furnace and AC pair
- Aurora controls platform
