High velocity systems can be beneficial to certain residential applications such as town houses, modern homes, and projects that require limited mechanical obstructions in regards to the architectural aesthetic. The versatility of high velocity systems allows them to be connected to different heating sources ranging from instantaneous tank-less water heaters to boilers. The primary reason why this particular type of heating system has become so popular in recent years is the smaller size of ductwork that can be used with a high velocity air handler as well as the possibility of being coupled with a boiler that also provides radiant in-floor warming to produce almost maximum comfort.
