Tml ELX00800R Hot water storage tank lt. 800 stainless steel AISI 316L rigid insulation

DHW Thermal Storage Tank 749 Litres in AISI 316L stainless steel (1.4404) – ELX00800R

The ELX00800R is a vertical DHW thermal storage tank with a capacity of 749 litres, manufactured in AISI 316L stainless steel (1.4404) by TML Industrie Loddo for domestic hot water (DHW) storage without an internal heat exchanger. The tank is designed for the installation of high-power electric immersion heaters via a large flanged inspection port, making it the ideal solution for systems with an external DHW generator (boiler, heat pump, solar thermal) that require a dedicated storage volume, or for direct electric heating.

Electric Heater Compatibility

The flanged inspection port of the ELX00800R is compatible with the TML REX electric heater range (30T, 40T, 50T, 75T, 90T, 120T for 800 and 1000-litre models) and with threaded heaters mounted on a CRI/CRV 180 adapter flange. This allows the tank to be configured as a large-capacity standalone electric water heater or as a buffer storage in multi-source systems.

Applications and Compatibility

The ELX00800R is suitable for: systems with an external DHW generator (gas boiler, heat pump, solar collector) requiring a separate storage volume; off-peak tariff installations with overnight electric heating; electric backup in hybrid systems; commercial and industrial applications with high DHW demand. The vertical design promotes thermal stratification, improving storage efficiency.

Standards and Certifications

The ELX00800R complies with: PED Directive 2014/68/EU (Art. 4 Par. 3), Italian D.M. 6 April 2004 N.174, ErP Directive 2009/125/EC.
