MAKING OIL IDEAL
Early this spring, a scheduled service took Bennett back to a home
in Fallston, Md., to complete a yearly tune up. Three years ago,
he and two other technicians installed an MPO-IQ in the 1,600
square-foot house, along with a 35-gallon Alliance tank.
Three heating zones draw from the 110 MBH boiler, each served
by a Taco 007 circulator. The stone-lined sidearm tank has prior-
ity. All radiation is fin-tube baseboard except for one hydronic
fan coil unit installed in a greenhouse attached to the south side
of the home.
If not for the greenhouse, a smaller boiler could have been installed.
"The original boiler was a 30-year old Burnham V1 with a tank-
less coil," said Bennett. "After one year with the MPO-IQ—which
has an outdoor reset sensor—the homeowner was happy to tell us
about her fuel savings."
Bennett and his fellow service techs noted the new unit is simple
to service and easier to maintain.
Rob Bennett arrives at another service call.
