heating water buffer tanks

We are still preparing products.

But you can look at other categories.

Heating water buffer tanks - IVAR.PUFFER PS

Heating water buffer tanks - with one integrated heat exchanger - IVAR.PUFFER PSR

Heating and cooling water buffer tanks - IVAR.PUFFER PSS

What is a heating water buffer tank used for? It balances the difference between the output of the heat source (e.g. a boiler or heat pump) and the current heat demand of the system, extends the life of the source and reduces the number of its switching cycles.
What is the difference between the PUFFER PS, PSR and PSS ranges? PUFFER PS has no heat exchanger, PSR has one integrated heat exchanger (e.g. for a solar circuit), PSS is also designed for cooling water in closed systems.
What volumes are the tanks available in? From compact 50 l units to large-volume tanks around 1000 l, in both floor-standing and wall-mounted versions.
Is additional thermal insulation necessary? The tanks are usually supplied with an insulating jacket; for larger volumes and lower heat losses we recommend checking the insulation thickness for the specific model.
