Solarbayer heating buffer tank P 500 heating cylinder / cold storage tank

This thermal storage buffer tank P500
is designed for energy accumulation in
heating and cooling applications,
particularly in HVAC and hydronic
systems. The diffusion-tight PU
insulation ensures efficient thermal
insulation. The four large connections
(1 1/2" female thread / DN40) for heat
sources 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.
