Tml MX0W01500R Maxiwarm combined storage tank lt. 1500 AISI 316L stainless steel without rigid insulation coil

Combined Thermal Storage Tank Maxiwarm 1472 Litres – Instant DHW Production – MX0W01500R

The Maxiwarm MX0W01500R is a combined thermal storage tank with a capacity of 1472 litres, designed by TML Industrie Loddo for instant domestic hot water (DHW) production via a high-efficiency corrugated stainless steel AISI 316L heat exchanger, combined with heating water storage in a carbon steel buffer. The system is configured buffer storage only, no primary heat exchangers.

Instant DHW Production – Corrugated AISI 316L Heat Exchanger

Unlike "tank in tank" systems, the Maxiwarm produces DHW instantaneously: mains water flows through the corrugated AISI 316L heat exchanger in contact with the hot buffer water and is heated without intermediate storage. The corrugated tube geometry maximises turbulence and exchange surface, delivering high thermal outputs: up to 113.4 kW at 65°C primary. The system requires no internal DHW storage and guarantees high hygiene standards through on-demand production with no water stagnation.

Multi-Energy Compatibility and Applications

The MX0W01500R is compatible with multiple heat sources: solar thermal collectors (lower heat exchanger steel spiral), biomass boiler (dedicated connections), backup boiler and heat generator at high or low temperature. The large 1472-litre capacity ensures adequate thermal storage for large residential buildings, villas and commercial premises. Buffer fluid must operate in a closed loop (oxygen-free).

Standards and Certifications

The MX0W01500R complies with: PED Directive 2014/68/EU (Art. 4 Par. 3), Italian D.M. 6 April 2004 N.174, ErP Directive 2009/125/EC.
