HI. I'M BOB VILA.
WELCOME HOME AGAIN
TO OUR 21st-CENTURY COLONIAL.
TODAY WE'RE SPENDING
MOST OF OUR TIME LOOKING
AT THE HEATING SYSTEM.
IT'S EUROPEAN TECHNOLOGY;
IT'S CALLED THE BOILER IN A BOX.
AND WE'RE GOING TO TOUR
THE JULIA WOOD HOUSE,
AN AUTHENTIC
18th-CENTURY COLONIAL.
STICK AROUND. IT'S GOOD
TO HAVE YOU HOME AGAIN.
CAPTIONING MADE POSSIBLE BY
SEARS
WITH US NOW
TO TALK ABOUT
HEATING TECHNOLOGY
IS ERLING ANDERSON
FROM AIM.
AND ALTHOUGH THIS IS
AN 18th-CENTURY KIND OF
REPRODUCTION HOUSE,
IT'S A 21st-CENTURY HOUSE
WHEN IT COMES TO
THE TYPE OF HEATING SYSTEM
WE'RE PUTTING IN, RIGHT?
CORRECT.
AND THIS IS WHAT YOU'D CALL
A BOILER IN A BOX?
YEAH, BOILER ROOM
IN A BOX.
SO THE WHOLE BOILER ROOM HAS
JUST ARRIVED IN THIS CRATE.
AND IT'S ALREADY
PUT TOGETHER?
IT'S ALREADY
ASSEMBLED,
READY TO BE HUNG UP
ON THE WALL.
NOW, ERLING, THIS IS ABOUT
A 3,500-SQUARE-FOOT HOUSE.
YES.
THAT'S LARGE,
AND THIS IS A COLD CLIMATE.
YEAH.
ARE YOU KIDDING ME?
THIS IS
A 175,000-BTU BOILER.
THIS RIGHT HERE?
THIS RIGHT HERE.
THIS WILL DO UP TO A
4,000-SQUARE-FOOT HOME
IN AROUND THIS AREA.
CAN WE TAKE THE PANEL
OFF .
SURE.
LOOK INSIDE.
HERE'S A...
OH, OK.
THE, UH...
THE FACT IS THAT
ALL THIS NEW TECHNOLOGY
FOR SUPERHEATING WATER...
IS ALWAYS A LITTLE BIT
DIFFICULT TO BELIEVE
BECAUSE IT'S CONTAINED
IN SUCH A TINY BOX.
WHAT ARE WE
LOOKING AT HERE?
IT'S A VERY,
VERY SMALL FOOTPRINT,
BUT IT IS
A FANTASTIC BOILER.
WHAT IT IS--
IT HAS A BUILT-IN
POWER VENTER
INTO THE UNIT.
SO WHAT IT DOES,
IT CREATES AN IMMENSE
AMOUNT OF HEAT,
AND IT MODULATES BETWEEN
175,000 AND 19,000 BTUs.
NOW, THE SOURCE OF
THIS HEAT IS GAS.
GAS, YES.
SO THERE'S GOTTA BE
A CHAMBER IN HERE
WHERE WE'RE--
YES. THIS IS
A STAINLESS-STEEL
CHAMBER IN HERE
WHERE THE GAS IS
GENERATED, WHERE IT
ACTUALLY FIRES--
THIS WHOLE AREA
RIGHT HERE.
AND THIS IS
ALL COPPER COILS IN
THIS AREA UP ABOVE.
SO YOU CAN HAVE THE FLAME
IN THERE AT HIGH HEAT
AND STILL HAVE THE WIRES
AND EVERYTHING ALL AROUND IT?
YES. AND THIS IS, UH,
IT'S REALLY UNIQUE,
THE WAY IT'S DONE,
BECAUSE IT--DEPENDING ON
HOW MUCH FLOW THAT GOES
THROUGH THE UNIT,
IS HOW HOT OR
HOW MUCH GAS IT USES.
SO WHEN IT'S COLD
OUTSIDE
AND WE ARE USING MORE
OF THE CIRCULATORS,
THEN IT'S DRAWING
MORE GAS,
AND THE FLAME
GETS HOTTER,
AND WE HAVE
A HIGHER BTU OUTPUT.
RIGHT. SO IT CAN
MODULATE ITSELF
DEPENDING ON THE
OUTSIDE TEMPERATURES.
AND THEN THIS IS WHERE
WE'RE ACTUALLY BEGINNING
THE PROCESS OF CIRCULATING
THE SUPERHEATED WATER?
YES. THIS IS
WHERE THE WATER IS
ABSORBING THE HEAT,
AND IT'S TURNING AROUND,
AND IT'S COMING OUT
THROUGH THESE PIPES.
BUT WHAT ABOUT
THE PRODUCTS
OF COMBUSTION?
THE COMBUSTION'S
GOING OUT THROUGH
THE VENTED HERE.
AND IT HAS
A POWER VENTER,
SO WE CAN JUST PUT
A B-VENTING ON IT
OR STAINLESS-STEEL
VENTING AND JUST GO
DIRECTLY OUTSIDE.
THERE WILL BE PIPING
COMING OUT OF HERE.
YES.
ALL RIGHT.
THEN ONCE YOU'VE
SUPERHEATED THE WATER,
YOU BEGIN THE
CIRCULATION PROCESS.
INCIDENTALLY, HOW HOT
DO WE GET THIS WATER?
THIS WATER GETS UP TO
ABOUT 185 DEGREES.
ALL RIGHT. AND THAT'S
THE TRADITIONAL SYSTEM
OF RADIANT HEAT
WITH HYDRONICS--
WITH HOT WATER.
YES.
THIS LOOKS RELATIVELY
FAMILIAR TO ME.
WHAT'S HAPPENING
OVER HERE?
WE GOT 4 DIFFERENT
ZONES, RIGHT?
WELL, WE HAVE
4 DIFFERENT
TEMPERATURES.
UH-HUH.
BECAUSE WHAT
WE REALLY WANT,
WE WANT TO HAVE
DIFFERENT TEMPERATURES
FOR DIFFERENT KIND
OF FLOOR MEDIAS.
SO WHAT IS
HAPPENING HERE IS,
THE HOT WATER COMES
OUT THROUGH HERE,
GOES IN HERE--
THERE IS
A BUBBLE ABSORBER
THAT TAKES THE AIR
OUT OF THE WATER.
COMES IN THROUGH HERE,
GOES INTO THIS MANIFOLD,
AND THIS IS
THE HOT-WATER SIDE
OF THE MANIFOLD.
IT COMES IN
THROUGH HERE AND GO
INTO THE CIRCULATOR.
AND THIS TOP SIDE,
AS YOU CAN SEE,
THERE'S NO CONNECTIONS
BETWEEN THE RETURN
AND THE SUPPLY,
SO THIS IS 185-DEGREE
WATER RUNNING INTO
THIS SECTION.
THIS IS MEANT FOR
THE BASEBOARDS.
OH, OK.
WE HAVE THE RADIANT
BASEBOARD IN THIS HOUSE.
AND THIS IS WHERE
YOU'RE CONNECTING ALL
THE BASEBOARD FEEDS?
THEY GET CONNECTED--YES.
THIS HERE WOULD BE LIKE
ZONE 1 OR LOOP 1.
THIS IS SUPPLY LOOP 1
AND RETURN LOOP 1.
OK. ARE WE READY TO
HOIST IT UP, THEN?
YES.
HOW MUCH DOES
THIS THING WEIGH?
AROUND...600 POUNDS.
ARE YOU KIDDING?
YEAH. OK.
1, 2, 3.
AND WE GOT A SHELF THERE
TO HOLD IT, I HOPE.
YEAH, THERE IT IS.
ALL RIGHT.
Andersen: THAT'S GOOD.
ALL RIGHT.
SO THEN, THE PIECES
OF PINE COME APART;
WE NO LONGER HAVE
A PINE BOX.
WE JUST HAVE
THE ENTIRE BOILER
HANGING ON THE WALL.
CORRECT.
AND THEN,
HOW DO WE DISTRIBUTE
THIS HEATED WATER?
WE HAVE TWO WAYS WE ARE
DISTRIBUTING THE HEAT
IN THIS HOUSE.
THIS HERE IS
THE SLIMLINE BASEBOARD.
OK, AND IT'S MADE
OUT OF WHAT?
ALUMINUM AND COPPER
IS THE ONLY TWO THINGS
THAT IS IN THIS PANEL.
I LOVE THE FACT
THAT IT'S SO SLIM.
AND YOU CAN PUT
A PIECE OF MOLDING
ON THE TOP
AND MAKE IT JUST
LIKE IT LOOKS LIKE
COLONIAL MOLDING.
EXACTLY.
AND HOW DO YOU GET
THE HOT WATER
FROM DOWN HERE
TO THE BASEBOARD
IN THE ROOMS?
IT'S ALL CONNECTED WITH
THIS KIND OF TUBING,
WHICH IS A PEX TUBING.
PEX--WHAT IS THAT?
CROSS-LINKED
POLYETHYLENE TUBING.
CROSS-LINKED
POLYETHYLENE TUBING.
AND THIS IS FLEXIBLE ENOUGH
THAT YOU CAN TAKE IT AROUND
ALL OVER THE PLACE?
YES. AND, SEE,
YOU DON'T WANT
ANY CONNECTIONS
BETWEEN THE ROOM
AND THE BOILER.
WHAT WE ARE DOING
IS RUNNING
ONE COMPLETE LENGTH
ALL THE WAY DOWN.
AND LIKE WE SAID
EARLIER,
YOU CAN HAVE UP TO
20 THERMOSTATS
IN THIS HOME.
WE DON'T WANT THAT MANY.
NOW, WHAT ABOUT RADIANT
HEATING SITUATIONS?
WHAT WE ARE DOING IS,
THERE IS ROOMS HERE
WHERE WE HAVE NO ROOM
FOR BASEBOARDS.
LIKE THE KITCHEN ABOVE.
YES. THIS PLACE IS--
THERE IS NO WALL SPACE
WHERE WE CAN PUT
THE BASEBOARDS.
SO THERE WE HAVE
THE TUBING--
AND THIS TUBING HAS
AN ALUMINUM CORE
IN IT, OK?
OK. THIS--
THE ALUMINUM CORE,
WHAT THAT DOES IS
BASICALLY TAKES THE
TEMPERATURE OF THE WATER
AND DISTRIBUTES IT
INTO THE VOID BETWEEN
THE FLOOR JOISTS.
THE ALUMINUM HELPS
DISPERSE THE HEAT.
I SEE. BUT IT'S NOT
ALL ALUMINUM, IS IT?
NO. IT IS
A PEX TUBING...
AS WELL.
THERE'S PEX WITH
A LAYER OF ALUMINUM
AROUND IT
THAT IS WELDED
THE WHOLE LENGTH.
AND THIS IS
PRETTY FLEXIBLE,
SO YOU JUST GO INTO
THE BAYS BETWEEN OUR...
GOING IN BETWEEN
THE FLOOR JOISTS, YES.
THE STRUCTURE,
AND PUT THESE IN. OK.
WELL, LET'S GET STARTED.
WE'RE BASICALLY
GONNA KEEP IT DOWN
ABOUT 3 INCHES
SO THEY DON'T
NAIL INTO IT
WHEN THEY ARE
PUTTING, UH...
WHEN THEY ARE PUTTING
THE FLOORS IN ABOVE.
THE BEAUTY OF THIS
STRUCTURAL SYSTEM
IS THAT THE HOLES
ALREADY ARE PREDRILLED.
YOU JUST KNOCK THEM OUT,
AND YOU CAN START
FEEDING THE TUBING
RIGHT THROUGH THERE.
AND WE DON'T GET
STARTED ALL THE WAY
UP AGAINST THE WALL
BECAUSE YOU'LL HAVE
THE KITCHEN CABINETS THERE,
AND YOU DON'T NEED TO
PUT RADIANT UNDERNEATH
THE KITCHEN CABINETS.
Andersen: OK, DAVE,
JUST GO TO THE NEXT ONE.
NOW WHAT WE DO IS
TAKE THIS ONE TIME.
GIVE ME SOME MORE
TUBING OVER THERE.
AND NOW THE LOOPS
ARE SIMPLY STAPLED
OR NAILED, ERLING?
WE NAIL THEM USING THESE
PLASTIC NAIL CLIPS.
YEAH, SO YOU JUST HAVE
PLASTIC NAIL CLIPS.
AND THEY DON'T HAVE
TO BE RIGHT UP AGAINST
THE SUBFLOOR.
THEY JUST FLOAT
IN THERE, HUH?
YES. WE BASICALLY--
WE KEEP THEM DOWN
ABOUT 2-3 INCHES.
IN THIS CASE,
THE CONTRACTOR,
HE LIKED THEM
DOWN LOWER.
NOW, WHAT'S TO KEEP
THAT HEAT FROM
RADIATING DOWN?
WELL, WHAT WE'RE DOING IS,
WE HAVE THIS ALUMINUM FOIL,
AND ALUMINUM--THIS CALLED--
IT'S AN REFLECTIVE--
REFLECTIVE
INSULATION, YES?
YEAH. AND WHAT THAT DOES,
IT'S 97% RADIANT REFLECTIVE.
AND THE SIDES GET BENT,
AND IT JUST GETS STAPLED
RIGHT UP INTO THE VOID.
SO THAT EFFECTIVELY
YOU'RE CREATING A SPACE
THAT IS LIKE A HEAT DUCT
IN BETWEEN EACH ONE
OF THESE JOISTS.
EACH ONE OF THESE
WILL BE A HEATED AREA.
IT'LL BE INTERESTING
TO SEE. OK.
THANKS, ERLING.
OK. THANK YOU VERY MUCH.
Vila: NEXT, WE'LL TOUR
THE JULIA WOOD HOUSE,
AN AUTHENTIC
18th-CENTURY COLONIAL
IN FALMOUTH, MASSACHUSETTS.
IF YOU EVER VISIT ANY
OF THE STATES THAT WERE
THE ORIGINAL 13 COLONIES,
OBVIOUSLY ANYTIME YOU FIND
AN OLD HOUSE,
IT'S APT TO BE
A REAL, GENUINE COLONIAL.
THE YELLOW HOUSE
JUST OVER MY SHOULDER HERE
COULD WELL BE
FROM THE LATE 1800s
OR THE LATE 1700s--
IT'S HARD TO TELL.
BUT WE'RE IN THE TOWN GREEN
IN FALMOUTH, MASSACHUSETTS,
AND WE'RE GONNA VISIT THE HOME
THAT IS THE HEADQUARTERS OF
THE FALMOUTH HISTORICAL SOCIETY.
THE HOUSE IS KNOWN AS
THE JULIA WOOD HOUSE
AFTER THE LAST PERSON
WHO LIVED HERE,
WHO DONATED IT
TO THE HISTORICAL SOCIETY.
BUT IT WAS BUILT
FOR A PHYSICIAN--DR. WICKS--
BACK IN THE LATE 18th CENTURY.
AND TO ME,
ONE OF THE INTERESTING THINGS
ABOUT THIS COLONIAL HOUSE
IS THE SCALE.
I FIND IT TO BE VERY SMALL,
YET WHEN IT WAS BUILT IN 1790,
IT WAS CONSIDERED TO BE
THE GRANDEST, LARGEST HOUSE
ANYWHERE ON
THE FALMOUTH TOWN GREEN.
NOTICE SOME OF THE DETAILING,
LIKE THE DOUBLE FRONT PORCH--
WHICH IS REALLY
VERY, VERY ROOTED IN
PALLADIAN ARCHITECTURE--
AND UP ON THE TOP OF THE ROOF,
A WIDOW'S WALK SAID TO BE ONE
OF THE LAST ORIGINAL REMAINING
WIDOW'S WALKS
FROM WHEN LADIES TOOK A LOOK
OUT TO SEA TO SEE WHEN THEIR
HUSBANDS' SHIPS WERE COMING IN.
BUT IT'S WHEN YOU GET
UP CLOSE TO IT
THAT YOU CAN REALLY APPRECIATE
THE SIZE OF THE HOUSE
AND NOT BE INTIMIDATED BY
THE STYLE.
BUT LET'S SAY HELLO
TO THE DIRECTOR--
THE EXECUTIVE DIRECTOR--
CAROLYN POWERS.
HELLO.
HI, CAROLYN.
HI, BOB. WELCOME.
THANK YOU.
NOW, I'VE BEEN TALKING ABOUT
THE SCALE OF THE HOUSE
BECAUSE IT IS RATHER SMALL.
BUT WHEN YOU WALK INTO
THIS CENTER HALL,
THIS CENTER ENTRY,
THE WALLPAPER REALLY
GRABS YOUR EYES.
TELL US ABOUT IT.
WE'RE VERY LUCKY
TO HAVE THIS WALLPAPER.
IT IS NOT ORIGINAL
TO THE HOUSE,
BUT IT WAS MADE IN
THE LATE 18th CENTURY
IN PARIS
AND WAS BROUGHT BACK
BY A SHIP'S CAPTAIN
TO HIS YOUNG BRIDE
AND WAS INSTALLED IN
A HOME IN ANOTHER
PART OF THE CAPE
WHICH WAS IN DANGER
OF DISAPPEARING.
SO WE WERE LUCKY ENOUGH
TO GET AHOLD OF IT,
AND IT WAS PUT UP
IN THIS HOUSE.
AND OF COURSE,
IT'S SCENES OF A PARK,
AND THERE ARE TEMPLES
AND PAGODAS AND MONUMENTS
AND PEOPLE STROLLING ABOUT.
VERY POPULAR.
I KNOW...MADE A LOT
OF PAPERS LIKE THIS.
WELL, THIS IS
LINEN PAPER,
AND IT WAS VERY EASILY
TAKEN OFF THE WALLS
AND WENT WITH A FAMILY
WHEN THEY MOVED.
FABULOUS. NOW, THE HOUSE
IS PRETTY MUCH INTACT,
AS I UNDERSTAND IT.
I MEAN, THE COMPONENTS
OF THE HOUSE SUCH AS
THIS DOOR HERE--
THEY'RE ALL ORIGINAL.
THAT'S CORRECT.
WE'RE VERY LUCKY TO HAVE
SUCH A WONDERFUL EXAMPLE
OF THE ORIGINAL
ARCHITECTURE,
INCLUDING
THE THIN WALLS.
THE PARTITIONS ARE ALL
JUST BOARD PARTITIONS?
RIGHT.
YEAH, YOU CAN SEE
THE PROFILE OF THE WALL HERE
NOT BEING MORE THAN 2,
MAYBE 2 1/2 INCHES
BECAUSE THERE WERE
NO STUDS INVOLVED.
IT WAS ALL JUST SIMPLY
BOARDS THAT WERE STOOD UP.
AND MAYBE IF THERE WAS
PLASTER APPLIED,
THEY WOULD ATTACH
SOME LATH AND THEN
PLASTER ON ONE SIDE.
BUT OBVIOUSLY ON THIS SIDE,
THEY JUST PUT THE PAPERS
RIGHT IN PLACE.
RIGHT. AND WHY
DON'T WE GO INTO
DR. WICKS' OFFICE?
SO THIS ROOM WOULD
HAVE BEEN THE OFFICE?
THAT'S CORRECT.
AT THAT TIME,
THERE WAS A DOOR
ON THE OTHER SIDE
OF THE ROOM,
AND PEOPLE COULD
COME IN AND SEE
THE DOCTOR
WITHOUT DISTURBING
THE FAMILY.
DIRECTLY FROM
THE OUTSIDE.
NOW, THE MANTELPIECE,
AGAIN, IS...
ORIGINAL.
YEAH, WHAT YOU'D CALL
KIND OF A FEDERAL-PERIOD
MANTELPIECE,
WITH ALL THE FINE JOINERY.
I'VE ALWAYS THOUGHT THAT
THE CARPENTERS, OR JOINERS,
WERE REALLY SHOWING OFF
THEIR WORK ON THE UNDERSIDE
OF THE MANTELSHELF
SO THAT IF YOU WERE SEATED,
YOU COULD APPRECIATE IT.
NOW, WHAT ABOUT SOME OF
THE FURNISHINGS IN HERE--
FOR EXAMPLE,
THIS VERY UNUSUAL CHAIR?
WELL, THAT CHAIR
WOULD HAVE BEEN USED
BY THE DOCTOR TO--
IT'S A REPRODUCTION--
AND HE WOULD HAVE SAT
AND HAD THE PATIENT
PUT THE AFFECTED PART
ON THE WIDE...
ON THE SURFACE HERE.
RIGHT.
I SEE.
SO THE DOCTOR ACTUALLY SAT
IN THE CHAIR, NOT THE PATIENT.
CORRECT.
AND THERE ARE TOOLS
FOR TOOTH EXTRACTION
IF NECESSARY.
HMM. SO A DOCTOR
IN THOSE DAYS
WOULD HAVE DONE
EVERYTHING INCLUDING
DENTISTS' WORK.
CORRECT.
OK. NOW, IS THIS
AN APOTHECARY CHEST
BEHIND US?
IT IS INDEED,
AND THE BOTTLES
THAT YOU SEE
IN THE FOREGROUND
ARE REPRODUCTIONS.
IN THE BACK ARE
ACTUAL BOTTLES FROM
DR. WICKS' TIME.
NOW, THE COLLECTIONS HERE
ARE PRETTY EXTENSIVE,
AREN'T THEY?
THE ENTIRE HOUSE
IS FURNISHED?
THE ENTIRE HOUSE
IS FURNISHED.
WE ARE THE OLDEST
HISTORICAL SOCIETY
ON THE CAPE,
ESTABLISHED IN 1900.
WE'VE BENEFITED
FROM THE GENEROSITY
OF MANY PEOPLE
WHO HAVE GIVEN US
THEIR FURNISHINGS.
NOW, GETTING BACK TO
THE ARCHITECTURE
OF THE HOUSE,
THE FLOORS THROUGHOUT HERE--
THE HALL AND IN HERE--
ARE SPATTER-PAINTED BOARDS.
VERY SIMPLE DECORATIONS
FOR A COUNTRY HOME,
BUT VERY SERVICEABLE.
IT HID THE DIRT
QUITE NICELY.
AND, OF COURSE, THEY DIDN'T
HAVE THE AVAILABILITY
OF ORIENTAL RUGS,
ALTHOUGH SOMETIMES
THEY HAD FLOOR CLOTHS.
AND THIS IS STILL A VERY
POPULAR TECHNIQUE TODAY.
NOW, THE DESK ACROSS THE WAY--
WOULD THAT HAVE BEEN TYPICAL?
IS THAT A LATE 1800s
OR LATE 1700s?
LATE 1700s.
LATE 1700s.
IT'S A NEW ENGLAND
PIECE.
WE'RE REALLY
NOT SURE IF IT
CAME FROM THE CAPE,
BUT IT CERTAINLY
FITS PERFECTLY IN
THIS DOCTOR'S OFFICE.
YES. IT LOOKS LIKE
IT'S A COUNTRY PIECE,
NOT A HIGH-STYLE
CITY PIECE.
BUT I LOVE
THE SLANT-FRONT FORM.
AND THEN OBVIOUSLY
THEY ALWAYS FOCUSED ON
SOME ASPECT OF
THE INTERIOR OF THE CASE
TO SHOW OFF THEIR
ABILITIES CARVING.
WELL, CAROLYN,
IT'S A FASCINATING
HOUSE. GOOD LUCK.
THANK YOU
VERY MUCH, BOB.
I'M SO GLAD YOU CAME.
THANK YOU FOR THE TOUR.
Vila: WHEN WE COME BACK,
WE'LL BE AT
OUR CONSTRUCTION SITE
INSTALLING DUCTWORK
FOR THE AIR-CONDITIONING SYSTEM.
NEXT TIME ON
BOB VILA'S HOME AGAIN,
WE'LL BE WORKING ON
THE HEATING SYSTEM
AT OUR 21st-CENTURY
COLONIAL HOUSE.
WE'LL BE USING
EUROPEAN TECHNOLOGY CALLED
"THE BOILER ROOM IN A BOX."
THIS COMPACT, EFFICIENT
HEATING PLANT
ARRIVES ASSEMBLED IN A CRATE
AND READY FOR INSTALLATION.
ALSO, WE'LL VISIT
THE JULIA WOOD HOUSE IN
FALMOUTH, MASSACHUSETTS.
BUILT FOR A PHYSICIAN
IN THE 1790s,
THIS DIMINUTIVE HOUSE FEATURES
MANY CLASSIC DETAILS.
SO DON'T MISS IT.
THAT'S NEXT TIME
ON HOME AGAIN.
NEXT TIME ON
BOB VILA'S HOME AGAIN,
WE'RE INSTALLING
A BOILER ROOM IN A BOX,
THE HVAC DUCTS,
AND TOURING
THE JULIA WOOD HOUSE.
DON'T MISS IT.
WELL, PART OF ALL THE ROUGH WORK
THAT GETS DONE
IS INSTALLING THE DUCTWORK
FOR THE AIR-CONDITIONING SYSTEM.
AND OUR INSTALLERS
ARE PETER MERIANOS
AND HIS COUSIN
PETER MERIANOS,
WHO ARE BOTH IN
THE BUSINESS TOGETHER.
NOW, WE'RE USING TRADITIONAL
SHEET-METAL DUCTWORK, RIGHT?
THAT'S CORRECT.
HOW DO YOU FIGURE IT OUT?
I MEAN, PIECES ARE LYING
ALL OVER THE PLACE HERE.
WELL, BASICALLY FIRST
WE PUT THE AIR HANDLER
IN THE ATTIC,
AND THEN WE JUST MEASURE
THE DISTANCES BETWEEN.
WE COME DOWN HERE,
TRANSFER THOSE
MEASUREMENTS
TO THE DUCTWORK,
CUT OUR HOLES,
AND PUT EVERYTHING
TOGETHER.
SO THIS IS ALL
WORK IN PLACE.
IT'S NOT OFF OF
BLUEPRINTS AND PLANS.
THAT'S CORRECT.
OK. AND YOUR BASIC
RAW MATERIAL
IS THE 5-FOOT LENGTH
OF DUCTING, RIGHT?
THAT'S CORRECT.
HOW DOES THAT
SNAP TOGETHER?
IT COMES PRECRIMPED?
IT COMES PRECRIMPED
FROM THE FACTORY
IN 5-FOOT LENGTHS.
AND AS YOU SEE MIKE
DOING RIGHT NOW,
IT JUST SNAPS TOGETHER,
AND THAT'S IT.
WE SECURE IT WITH
SHEET-METAL SCREWS.
SO BASICALLY THE SECTIONS
GET PUT TOGETHER
WITH SHEET-METAL SCREWS.
AND THEN DO YOU HAVE TO
ADD THIS FOIL TAPE?
YOU DON'T HAVE TO,
BUT WE DO THAT
BECAUSE IT GIVES YOU
A MUCH TIGHTER JOB.
MM-HMM. SO THAT,
REALLY, AN A-CLASS JOB
WOULD BE SCREWED TOGETHER
LIKE THAT AND THEN TAPED.
AND THEN WHAT'S HAPPENING
AT THIS END OVER HERE?
WELL,
THIS END HERE, WE--
IN ORDER TO JOIN
THIS PIPE TOGETHER,
WE HAVE TO CRIMP
THIS END TO MAKE
THIS END SMALLER
SO THAT THE LARGER END
WOULD FIT.
OF COURSE, BUT YOU'RE
REDUCING THE SIZE OF THE...
THAT'S CORRECT.
AS WE GO FURTHER
DOWN THE LINE,
THE DUCTWORK SIZE
GETS REDUCED.
AS THE TRUNK GETS LONGER,
THE DIAMETER GETS REDUCED.
AND THEN THIS END HAS TO
BE CAPPED OFF, RIGHT?
RIGHT, BUT BEFORE
WE CAP IT OFF,
WE HAVE TO CRIMP IT
SO THAT THE END CAP
WILL FIT.
Vila: AND SO THE CRIMPING
IS DONE BY HAND.
RIGHT.
AND IT'S A NIFTY TOOL
THAT'S SPECIFICALLY
FOR THIS KIND OF JOB.
SO ANYTIME YOU HAVE
TWO SIMILAR DIAMETERS
COMING TOGETHER,
YOU GOTTA CRIMP IT...
TO REDUCE IT.
AND THEN WHAT?
YOU PUT A COUPLE
MORE SCREWS THERE?
NOW, AT SOME POINT,
YOU HAVE TO HAVE LINES
THAT COME OFF
OF THIS, RIGHT?
YES, THAT'S RIGHT.
HOW DO YOU CONNECT THEM?
WE FIRST
HAVE TO CUT--
AFTER, AGAIN,
WE GO BACK TO OUR
MEASUREMENTS--
AND WE HAVE TO CUT
A ROUND HOLE.
AND THEN WE, UH--
JERRY'S DOING THAT
RIGHT NOW.
Vila: THAT IS COOL.
AND THAT'S HOW YOU
DO IT IN THE FIELD.
AND THEN THERE'S
ONE MORE TO CUT.
NOW, I NOTICED
MOST OF THE DUCT
IS INSULATED.
Merianos:
THAT'S CORRECT.
AND HOW DOES THAT
GET DONE?
WELL, WE USE
THIS INSULATION
WITH, UH--
IT'S CALLED
VINYL WRAP.
IT'S INCH-AND-A-HALF
INSULATION WITH...
SO IT'S FIBERGLASS,
INCH-AND-A-HALF.
RIGHT.
AND IT GETS STAPLED
ONTO THE DUCTWORK.
...THIS PRODUCT
HERE.
SO YOU FOLD IT UNDER
AND PICK UP TWO EDGES.
..ANOTHER ONE
OF THESE.
FOLD IT UNDER...
AND PICK UP THE EDGES.
I NEED ONE MORE,
PETER.
Vila: WE'LL CONTINUE WITH
THIS PROJECT IN A MOMENT,
SO STICK AROUND.
Vila: ALL RIGHT,
AND THEN WE CUT
THE INSULATION
OUT OF THE HOLE.
AND WHAT IS THE PIECE
THAT YOU'RE PUTTING IN THERE?
Merianos: THIS IS
A STARTING COLLAR.
A STARTING COLLAR,
BECAUSE IT STARTS
A SECOND LINE GOING OFF.
THAT'S CORRECT.
THE FLEXIBLE LINES ARE
GONNA ATTACH TO THAT.
YEAH. AND WHAT'S THIS?
THIS IS
A VOLUME DAMPER THAT--
YOU CAN REGULATE THE
PRECISE AMOUNT OF AIR
THAT EACH VENT GETS
FROM THE ATTIC.
THAT'S WHERE YOU
BALANCE THE SYSTEM.
THANKS, PETER. THANKS, PETER.
WE'RE RUNNING OUT OF TIME.
COME HOME AGAIN NEXT TIME,
WHEN WE'LL BE SHINGLING
THE HOUSE
WITH PREFINISHED EASTERN
WHITE CEDAR FROM MAIBEC,
AND WE'LL INSTALL
A GAS FIREPLACE.
TILL THEN, I'M BOB VILA.
IT'S GOOD TO HAVE YOU
HOME AGAIN.
