After purchasing a house in the historic district, our fiance & I started looking into different types of heating & cooling systems, the two of us were limited by the narrow walls & age of the home.
There simply isn’t satisfactory space to accommodate a conventional duct system.
The two of us also weren’t willing to compromise the historical integrity of the house by cutting up floors & pulling down walls & ceilings. The previous owners had gotten by with electric space oil heating systems & portable air conditionings. The two of us hoped to figure out something less cumbersome & unappealing, however after consulting with a local Heating & Air Conditioning supplier who specializes in older homes, the two of us l earned about high-velocity temperature control. This type of plan uses really small & bendy ducts that are able to be routed through the cavities of walls & ceilings & around plumbing separate from disruption or damage. The unit operates through a process called aspiration. The heated or cooled air enters the room through strategically localed vents in a high-velocity stream that creates a gentle suction. This draws the air in the room into the stream, where it abruptly mixes & circulates. The result is a quick rise or lowering of temperature & no drafts & fluctuation. The temperature from floor to ceiling & room to room respectfully varies no more than two degrees from the temperature control setting. The narrow ducts are wrapped & insulated to minimize air loss between the air handler & delivery into the numerous rooms… WIth about a seventh of the surface area of traditional air duct, there’s far less energy waste. While traditional ductlabor loses up to 25% of heated/cooled air, the high-velocity plan limits waste to 5%.
