Tml ELV00400R Hot water storage tank lt. 400 Rigid Insulation Porcelain Glass

DHW Thermal Storage Tank 414 Litres in vitreous enamel carbon steel S235Jr – ELV00400R

The ELV00400R is a vertical DHW thermal storage tank with a capacity of 414 litres, manufactured in vitreous enamel carbon steel S235Jr 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 ELV00400R 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 ELV00400R 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 ELV00400R complies with: PED Directive 2014/68/EU (Art. 4 Par. 3), Italian D.M. 6 April 2004 N.174, ErP Directive 2009/125/EC.
