Multi-Zone HVAC System

Project: Modular Mountain Retreat, Episode 9, Part 3



Bob gets an update on the continuing progress on the exterior of the modular mountain retreat. First, Bob looks in on the installation of Chadsworth Columns' PolyStone columns on the back deck support. These columns are custom manufactured to a homeowner's specifications and are resistant to moisture and insects.

Next, Bob sees that the Cultured Stone faux stone finish is completed on the foundation, before he goes off to revisit Edith Wharton's home, The Mount, in Lenox, MA, for a tour of the revived gardens.

Back at the project site, the mechanical systems are being installed. Mark Gallivan from Sears and Brent Morin from Morin Mechanical are putting in the new Carrier HVAC system.

Chris Vila visits with Jack Frederick as he installs a Rinnai Continuum tankless water heater. The Continuum is a compact, on-demand water heater, which only makes hot water when there is a demand for it.
Part 1: Reviewing the Modular Home's Exterior
Part 2: Tour of the Gardens at The Mount
Part 3: Multi-Zone HVAC System
Bob meets with Mark Gallivan from Sears HVAC, and Brent Morin from Morin Mechanical Services, to review the heating system installation in the modular home.

The high-efficiency, state-of-the-art Hydro-Air system uses components of traditional boilers, humidifiers, variable-speed fans, electronic air cleaners, and three exterior condensing units.

The boiler produces hot water for both a forced air unit and a baseboard radiant heating system. The forced air unit allows for a consistent level of humidity in the house, something radiant-only units traditionally cannot accomplish.

There are seven zones employed in the home's heating and cooling system. The cast aluminum heat exchanger in this unit transfers heat three times faster than a traditional heat exchanger. The boiler uses a direct venting system that takes air directly from outside and vents it through a flue located in the center of the intake vent.
Beautifully sited on wooded acreage with breathtaking views of some of the most beautiful countryside in New England, this Arts and Crafts style bungalow certainly doesn't look factory-built. You'd never know it was a modular home unless Bob took you to the Pennsylvania factory where it was built, almost from start to finish.

The house goes down the assembly line from framing, through wiring and plumbing, all the way to the installation of flooring and priming for paint.

The house is trucked to its pre-fabricated foundations on the lot, and start all the finishing touches that will prove that a modular house doesn't have to be a cookie-cutter affair.
