6. PRODUCT INFORMATION & SPECIFICATIONS >
syncFURNACE OD is a combined, modulating gas-fired tankless condensing water heater and hydronic fan-
coil unit, designed to provide space heating via warm-air fan-coil and potable water heating on-demand.
Available with an internal add-on to provide whole home DHW re-circulation. It is 100% factory tested
and calibrated.
An advanced internal controller operates both the modulating gas-fired tankless condensing water heater
and hydronic fan-coil unit. The controller monitors and adjusts the combined system to minimize energy
usage during operation.
syncFURNACE OD incorporates a stainless steel, modulating gas-fired tankless condensing water heater
that is factory set for use with Natural Gas (optional factory set propane model is available).
The hydronic fan-coil unit has an internal pump circulates hot water through a water coil heat exchanger.
The hot water coil is built using copper tube and aluminum fins to provide excellent heat exchange. A
blower inside the fan-coil is used to move building air across the coil and distribute heated air back out to
the building. In addition to space warm-air heating, the fan-coil unit can also perform continuous air-
circulation (fan-only) and air-conditioning (air-conditioning coil & condenser sold separately) functions for
the building. The fan-coil unit is available in either low-velocity (low static pressure) or high-velocity (high
static pressure) configuration.
