Buffer Tanks
Panasonic offers a variety of stainless steel
buffer tanks in different sizes. A buffer tank can
reduce the number of start and stop sequences
for the air/water heat pump, thus prolonging
the lifecycle of the heat pump, increasing the
energy efficiency of the heating system and
providing greater comfort.
