ApplicationCombined water heating system in the tank, using energy from various sources, traditional and alternative, using heat exchangers inside the tank. The tank also acts as a collector. From the collector, hot water enters all heating systems: hotter water is from the top of the tank, and less hot water is used for underfloor heating systems from the bottom of the tank. The system for heating hot water supply consists of a buffer tank.
ExecutionMade of high quality S235JR EN10025 carbon steel, assembled and welded by automatic welding. Non-removable spiral heat exchangers made of S235JR EN10025 carbon steel welded to the tank. Has an inspection hatch for inspection and cleaning of the tank (built into the tank for hot water supply). BWE-T: AISI 316 L stainless steel hot water tank without heat exchangers. BWE-ST: AISI 316 L stainless steel hot water tank with one non-removable heat exchanger. BWE-SST: AISI 316 L stainless steel hot water tank with two non-removable heat exchangers. BWV-T: tank without heat exchangers, enamelled carbon steel internal hot water tank. BWV-ST: tank with one heat exchanger, internal hot water tank made of enamelled carbon steel BWV-SST: tank with two heat exchangers, internal hot water tank made of enamelled carbon steel
Anti-corrosion coatingBWV Internal anti-corrosion coating (Enamel) obtained by high temperature treatment in an oven at 860 ° C. Fully complies with the requirements for drinking water according to DM 174/2004 (Italian standards) and the CEE directive 76/893. BWE Completed after welding: weld passivation and surface etching.
Cathodic protectionThreaded magnesium anode.
Insulation and type of outer coverFor mod. capacities from 500 to 700 liters - rigid polyurethane insulation, and for the rest - flexible polyurethane insulation, outer PVC cover with zipper and thermal cover.
CertificatesComplies with directive 97/23 / CE Art. 3 - Part 3.

To select the required storage volume, it is possible to combine several tanks into a cascade.

The storage tank is selected for the previously selected heat source and is calculated in such a way that it can accumulate all the heat generated by this source, or for the consumer of which it should be provided with heat generated before the time of heat consumption by a low-power source.

The priority in the selection of the capacity will be the source if its power or the time of heat input is limited.

The priority in the selection of the capacity will be the consumer, if it is required to cover a given heat load in a certain time.
The additional volume of water formed during heating to the maximum temperature is ~ 3.5% of the nominal volume of the container.
