Buffer tanks for heating and heat pumps
A buffer tank absorbs heated heating water and releases it again at a later time. As a result, heat generators have to start less often, and heat from solar or surplus electricity can be stored temporarily. This category is aimed at homeowners, installers and planners who want to add extra storage volume to a heating circuit.
The volume is the first decisive factor. It depends on the heating load, the heat generator and the desired bridging time, which your specialist company calculates. Also check the installation height and delivery dimensions, whether you need a tank with or without a heat exchanger coil, and which connections your hydraulic diagram provides for.
Our range includes the floor-standing buffer tanks from SOLIBUFFER with 132, 170 and 245 litres, each without a coil, as well as a 50-litre buffer tank from the TRINNITY brand.
Note that a buffer tank needs space and load-bearing capacity at the installation site, because it weighs considerably more when filled than when empty. Good insulation of the connections and pipes reduces heat losses. A look at the documentation of your heat generator often shows which minimum volume the manufacturer recommends.
If you are unsure which volume suits your heating, you can reach us on +49 931 760 260 40 or by email at kontakt@energie24.shop. The actual system design should be carried out by a heating specialist.
Frequently asked questions
How many litres make sense for my house?
A blanket number of litres would not be reliable, because the heat generator, heating load and diagram set the framework. Your heating engineer calculates the volume. If you give us the key data, we will help with product selection.
What does “without coil” mean?
A tank without a coil has no built-in heat exchanger, as used for solar thermal systems, for example. It serves as a pure buffer tank in the heating circuit. Whether that is sufficient for your system is determined by the system design.
Can I connect the tank myself?
Work on heating and water pipes belongs in the hands of a specialist company. This also applies to insulation, safety fittings and commissioning, so that your system works reliably and in line with the applicable requirements.
