Hoval WP 300 FM – 300-liter hot water storage tank

Hot water reserve for daily consumption needs. According to the original data plate, the offered storage tank is from 2004, with factory identifier 405 469354.

Key features and practical benefits

• 300-liter tank: stored hot water can be provided; consumption and reheating methods must be sized together based on the number of users.
• Enamelled steel: the data plate contains material specifications according to DIN 4753 T3, T6. The condition of the protective layer and corrosion protection must be checked upon receipt.
• Maximum 10 bar operating pressure: factory limit for connection to the water network and safety fittings.
• 13 bar factory test pressure marking: not a permitted operating pressure and does not verify a recently performed pressure test.
• Maximum 95 °C operating temperature: technical upper limit; usage temperature and scalding protection must be adjusted to the system.
• Electric heating element field on the data plate: the specific type, output, and presence of the element are not verified. The heat exchanger surface field is also blank, therefore no heating output is stated from these.

A downloadable factory manual for the exact WP 300 FM model has not been found yet. Numerical data originates from the original data plate. The documentation for the CombiVal WPE heat pump unit belongs to a different model.
