Limoges was also happy the replace-
ment job went easily. Eastern Propane
took care of removing the old boiler
and tank by working through Twin
Valley Heating, a firm managed by
Mark's son, Calvin Limoges, and Trevor
Stickney.
To reduce field installation time,
they built the boiler's panel—complete
with circulators, components and near
boiler piping—at the shop. Key com-
ponents included copper supply and
returns, with Taco 007 circs on the sup-
ply side, and spigots on the return for
easy purging of zones, and for mainte-
nance. A Taco 4900 air eliminator and
was piped upstream from the Watts
expansion tank, water feed and back-
flow preventer.
"I really like using the 4900 air elimi-
nators," commented Limoges. "We're
fond of these because of their stainless
steel pall rings to remove microbub-
bles in the system. They're much more
resistant to corrosion from chemicals
in solution than units with internal
brushes made of copper."
Circulated fluids are tempered with
a standard thermostatic mixing valve.
The system's three zones, each served by
a 007, deliver heat to the single upstairs
apartment, and to both lower apart-
ments. "The circs are wired into the
boiler control to respond to a call for
heat from a programmable thermostat
in each zone," added Calvin Limoges.
"The boiler itself is just a 17-inch
wide, 31-inch high, and 15-3/4-inch
deep cabinet and weighs just 100
pounds," added Limoges. "So it was
real easy to carry into the house and
downstairs into the basement without a
hand truck. The compact size would fit
into a closet or alcove—but in this case,
it certainly took up less space in the
basement than the old setup."
After one of the toughest winters on
record, Mark Limoges was pleased that
the project was ready to go when the
bad weather hit. "Knowing I had two
families counting on this replacement
system, I was glad to hear they were
satisfied with the availability of heat and
hot water rather than hear complaints
in the dead of winter," he said.
