Tanks for domestic hot water, production and storage:

The design of our storage tanks and their extra-thick rigid mould-injected PU thermal insulation, gives them an extraordinary energy storage capacity in order to keep the DHW temperature for long periods of time without the need for any additional energy inputs, which leads, in addition, to the definitive contribution to environmental care, and to continuous savings for the user throughout the operational life of the cylinder.

Bacterial proliferation such as “Legionella” inside the domestic hot water storage cylinders, should be avoided from the design of the storage tank itself, with heating systems that avoid “cold areas” (<40 ºC), or with storage temperatures clearly lower than that of the tank. As an example of “anti-Legionella” design, we propose our "double wall" models, with total temperature homogeneity inside the cylinder and made of stainless steel as the hygienic material for excellence. All our models with heating coils also take into account this phenomenon, and are designed with geometries adapted to heating from the bottom of the storage tank, thus avoiding cold areas or areas with the possibility of bacteria proliferation.

Buffer tanks in hot water installations are considered lung tanks in the primary heating circuit, or as a primary energy source to connect different heating systems for DHW production or heating water. In this second case, it is essential to have the primary water storaged at different temperatures for the correct operation of the systems connected to the tank. In the case of our inertia buffer tanks with stratification system, they storage water in the primary circuit in different temperature zones.

A multifunctional tank allows several primary heating systems to be installed at the same time, for the production and storage of domestic hot water, and also for the use in heating circuits. Basically, it consists of a DHW storage tank with or without an internal coil (back-up boiler), with a “double wall” primary circuit, which acts as a heating circuit and a buffer tank to connect, for example, a heat pump, and with coil inside the primary circuit for connection to solar water heating systems (such as solar collectors).

Our recommendation is to inspect the condition of the anodes at least once a year and change them if necessary. Obviously neither all geographical areas nor their waters are the same. The consumption of the anodes will depend on the aggressiveness of the water, its characteristics and chemical composition.
