Austria Email WPPK

The Austria Email WPPK 301/100 B is an all-in-one heat pump storage system combining a 284 L enameled domestic hot water cylinder and a 100 L heating buffer tank in a single compact footprint.

The Austria Email WPPK 301/100 B is an innovative, high-efficiency "All-in-One" storage system engineered specifically for modern heat pump installations, combining a domestic hot water (DHW) cylinder and a heating/cooling buffer tank into a single space-saving unit.

The domestic hot water tank and the heating buffer tank are hydraulically completely separated within the vessel. This dual-vessel combination delivers significant space savings in plant rooms and utility areas while substantially simplifying installation, pipework, and commissioning.

Key Product Advantages:

• All-in-One Dual Tank Concept: Combines a 284-liter enameled DHW cylinder and a 100-liter buffer tank within a single vertical footprint.
• Space-Saving Footprint: Drastically reduces floor space requirements compared to installing standalone cylinders and buffer vessels.
• Optimized for Heat Pumps: Guarantees the mandatory minimum flow rate in heating circuits, ensuring seamless defrost cycles and stable operation.
• Extended Compressor Service Life: Eliminates frequent heat pump cycling (short-cycling), minimizing wear and tear while improving seasonal efficiency.
• Integrated 3.2 m² High-Performance Coil: Dual 1" internal heat exchanger surface delivers rapid reheating times and high continuous DHW volume.
• Stratification Baffles: Internal stratification pipes ensure optimal thermal layer separation and superior buffer efficiency.
• Heating & Cooling Operation: Fully suitable for year-round heating and active/passive cooling operation.
• Premium Corrosion Protection: Enameling according to DIN 4753-3 ensures sanitary water hygiene and long-lasting durability.
• Service & Maintenance Friendly: Inspection flange (blind flange TK 180), electric immersion heater connection (1½" IG), and height-adjustable leveling feet.
