Why choose the ALPS EXCLUSIVE Combination Tank 300/150L(V2)?

Need a solution for high hot-water demand and stable heating support? The ALPS EXCLUSIVE WKB-HV-300/150L(V2) combines a 300-litre DHW tank with a 150-litre heating buffer in one compact stainless-steel unit.

Thermal separation for maximum efficiency

The thermally separated sections minimise energy losses. The buffer reduces boiler/heat pump cycling, while the DHW tank ensures a steady supply – even at peak times.

Efficient heat exchanger

The large heat exchanger provides rapid heating and maximises available energy. Ideal for pairing with **/warmtepompen** (heat pumps), **/zonneboilersystemen** (solar), or an existing **/cv-installatie**.

Heating and cooling in one

The buffer not only supports heating but also low-temperature cooling, e.g. with underfloor or surface systems in summer.

Durable stainless steel build

Made of high-grade stainless steel, corrosion-resistant and built for longevity. Thick PU insulation reduces heat loss, improves efficiency and lowers running costs.

Easy to integrate

  • Compact footprint: DHW and buffer in one unit
  • Connections designed for quick installation
  • Prepared for optional electric element
  • Suitable for new-build and retrofit systems

Who is this model for?

  • Families with high hot-water demand
  • Small commercial uses such as B&Bs or sports clubs
  • Hybrid systems combining multiple energy sources
  • Projects prioritising efficiency and space saving

Conclusion

The ALPS EXCLUSIVE WKB-HV-300/150L(V2) delivers hot-water comfort and heating support in one compact stainless-steel tank. With large capacity, efficiency and long service life, it is a future-ready solution. Hewa provides full support with selection, delivery and installation.
