At Takagi, we place the safety and reliability of
our products above all else. By incorporating
technologically advanced safety features into
every model, we provide the assurance and
peace of mind that can only come from a
Takagi quality product.
Air-Fuel Ratio (AFR) Sensor
Takagi’s unique AFR sensor monitors and
maintains proper combustion at all times.
Together with the onboard computer, this
system will adjust the fan motor speed to
ensure that air and fuel have a proper
mixture ratio, minimizing emissions and
maximizing efficiency.
Additional Safety Features
Freeze Protection:
Every heater in Takagi’s tankless lineup has
an internal freeze protection system, which
is rated to protect the heaters when installed
in sub-freezing conditions. This system works
to keep water temperatures within the heat
exchanger from falling below a certain level,
preventing freeze damage.
Hi-Limit Switch:
Ensures that water temperatures do not exceed
safe levels. Before the water temperature can
even reach these unsafe levels, the hi-limit
switch activates by disengaging the gas valves,
effectively shutting down the water heater.
Overheat Cutoff Fuse:
Ensures that there are no breaches in the
heat exchanger drum. In cases where enough
physical damage might have been done to
the water heater to lead to a breach in the
heat exchanger drum, the overheat cutoff fuse
reacts by shutting down the water heater if
the surface of the heat exchanger retains too
much heat.
