ALPS EXCLUSIVE WKB-HV-300/100L(V2) – Stainless Combination Tank (300/100L)
Other variants
- 2-in-1: 300L DHW + 100L heating buffer
- Thermally separated sections, minimal losses
- High-output heat exchanger for rapid recovery
- Supports both heating AND cooling
- Stainless tank with premium insulation
- Space-saving: fewer pipes, lower install cost
All-in-one DHW and buffer storage for heating and cooling
The ALPS EXCLUSIVE WKB-HV-300/100L(V2) combines a 300-litre domestic hot water tank and a 100-litre heating buffer in a single stainless-steel unit. With thermally separated sections, DHW temperature remains stable while the buffer smooths load peaks in the heating circuit.
One unit instead of two
Separate tanks mean more footprint, pipes and standby losses. This combination tank reduces installation time and cost while improving plant-room clarity.
Thermal separation = system efficiency
- The buffer reduces boiler/heat-pump cycling and evens out demand.
- The DHW section delivers a steady hot-water supply at multiple draw-offs.
- Less unwanted heat transfer between sections keeps energy where it’s needed.
Works with sustainable sources
The large heat exchanger maximises energy from heat pumps, solar boiler systems or an existing central heating boiler. Considering alternatives? See our buffer tanks and indirect water heaters.
Cooling capability
With low-temperature surface systems, the buffer also supports cooling, keeping indoor conditions comfortable in summer.
Built to last
Corrosion-resistant stainless steel and premium PU insulation keep losses low and maintenance minimal. Water stays hot longer, and overall efficiency improves.
Installer-friendly
- Small footprint: DHW + buffer in one cabinet.
- Well-placed connections for quick installation and service.
- Sensor/controls ready, optional electric heater for back-up/boost.
Who benefits from 300/100L?
- Homes with higher DHW demand.
- Projects with variable load and limited plant-room space.
- Hybrid systems (heat pump + boiler) needing extra buffer volume.
Conclusion
The WKB-HV-300/100L(V2) delivers comfort (300L DHW) and stability (100L buffer) in one compact unit. Fewer components, fewer pipes, fewer losses – ready to future-proof your system?
