Solarbayer heating buffer tank P-1000 cold storage tank / heating cylinder

This thermal storage buffer tank P1000
is designed for energy accumulation in
heating and cooling applications,
particularly in HVAC and hydronic
systems. The PEXL insulation, which
inhibits condensation, and additional
fleece insulation ensures efficient
thermal insulation. The four large
connections (3" female thread / DN80)
for heat generators and consumers make
the storage tank flexible in use. Ideal
as a hydraulic switch for heat pumps
with heating and cooling operation.
In addition, four connections for
thermometers and sensors as well as a
further connection for an electric
heating rod are available.
