Solarbayer heating buffer tank PS-300, storage cylinder

Heating/cooling buffer tank PS300
with diffusion-tight PU insulation and
6 connections with baffle plates for
for heat sources and consumers. Ideal
hydraulic separation for heat pumps,
usable for heating and cooling. The
integrated heat exchanger also enables
the connection of a solar system.
Additional connections for thermometer,
sensors and electric heating element.
