The HDW 750 L heat pump storage tank is equipped with a particularly large heating surface and is therefore ideal for systems with high heat pump outputs. Thanks to its robust construction and excellent insulation values, it is also suitable as an auxiliary storage tank for oil, gas, solids and similar applications.

The insulation is available in two variants: For types up to 500, 75mm PUR rigid foam (directly foamed) is used, while from type 750 onwards, high-quality fleece insulation (Made in Germany) is used. A double-wound smooth tube heat exchanger (1 inch tube) ensures optimal heat transfer. Made from robust quality steel S275JR, designed in accordance with EN 10025 and EN12897:2006 and enamelled in accordance with DIN 4753, this storage tank represents the highest quality workmanship and durability.
