Sunsystem Buffer Tanks accumulate the heat generated by boiler and are highly recommended for each heating system.  They ensure the optimum operating performance of the biomass boiler, permitting it to function at a nominal power output even when the heating system does not always call for the heat produced. The accumulated heat is stored inside the buffer tank and can be used even when the boiler itself has cooled down.


Removable Fleece insulation with thickness 100mm and outer casing of  PVC with RAL 9006 colour. Multi-position mounting of temperature sensor. Primer coated on the outside of the tank - All threads are internal with the Inlet/Outlet arrangement at 90 degrees for easy and convenient installations.

Key Benefits of using a Buffer Tank

Having a Buffer Tank as part of an installation is extremely important. Some manufacturers will say that you don't need a buffer tank with their boiler, but the evidence shows that they are always better with.

  Increases the overall efficiency of the heating system
  Hot water is available on demand
  Buffer Tank can be used to heat your DHW indirectly
  The Biomass boiler fuel consumption is less
  Prolongs the life of the boiler by reducing boiler cycling
