Why our Buffer Tank?

AE buffer tanks are suitable for all hot water central heating systems, regardless of whether they are powered by solid-fuel or oil-fired boilers, heat pumps, solar energy systems or continuous flow heaters (gas or electric).


Several buffer tanks can also be combined in a row, meaning the tank volume can be adjusted individually depending on the requirements. Furthermore, the buffer tanks can also be used for cold water storage in cooling processes (up to 3 bar operating / system pressure) or heat recovery in industrial facilities (suitable Armaflex insulation must be provided by the contractor in this case).


Naturally, AE also offers the required supplementary programme for the buffer tanks, such as the possibility of installing heat exchangers or electric heaters, depending on the required output.
