ALPS EXCLUSIVE WKB-HV-300/100L - Combi boiler (300/100L)

One system for hot water, heating and cooling

Want to save space without compromising on performance? The ALPS EXCLUSIVE WKB-HV-300/100L is a smart combination boiler that combines a 300-litre domestic hot water boiler and a 100-litre buffer tank in one compact unit. This gives you a complete solution for domestic hot water, space heating and cooling.

Compact design with dual function

Traditionally, separate appliances are required for hot water and buffer capacity. Why would you still opt for two separate units? With the WKB-HV-300/100L, you benefit from an integrated system that both heats drinking water and buffers central heating water. The result: less space required, lower installation costs and a more efficient heating system.

Double heat exchanger for high efficiency

This combination boiler is equipped with a large-surface double heat exchanger, specially designed to work with heat pumps, solar boiler systems and conventional central heating installations. The tap water compartment heats up quickly, while the buffer tank compensates for temperature fluctuations. This ensures optimal use of energy and a stable hot water supply and constant heating at all times.

Hot water and buffer capacity in balance

• 300-litre tap water boiler: provides ample domestic hot water, suitable for families and smaller commercial applications.
• 100-litre buffer tank: increases the volume of the heating circuit and prevents heat pumps from switching on and off unnecessarily often. This extends the service life of the installation and increases energy efficiency.

Also suitable for cooling

A unique advantage of the WKB-HV-300/100L is that the buffer tank can be used not only for heating but also for cooling. If you combine this system with surface cooling (e.g. underfloor heating in cooling mode), your indoor climate will remain pleasant – even on hot summer days.

Condensation protection and durability

Condensation can occur when used for cooling. That is why the WKB-HV-300/100L is equipped with a special anti-corrosion coating that protects the tank against condensation and wear. Together with the robust construction made of S235JR steel and the high-quality insulation, you are assured of years of reliable performance.

Optional electric heating element

Would you like extra flexibility or a back-up facility? The combination boiler can be optionally equipped with electric heating elements, both in the tap water section and in the buffer tank. This provides security during peak loads or as an additional heating source.

Who is this model suitable for?

• Households that want buffer capacity for their heating system in addition to hot water
• Businesses and small commercial applications, such as offices or sports clubs
• Hybrid installations, where multiple heat sources work together
• Projects where space saving and energy efficiency are key

Practical and easy to install

Thanks to its compact dimensions (70 × 70 × 176 cm) and the smart placement of connections, the WKB-HV-300/100L can be easily integrated into both existing and new installations. What's more, with a single unit, you save on installation space and materials, making this model not only practical but also economically attractive.

The ALPS EXCLUSIVE WKB-HV-300/100L combination boiler offers a unique combination of hot water comfort, heating support and buffer capacity. With its generous capacity, powerful heat exchanger, versatile applications and durable construction, this system is the ideal choice for those looking for efficiency, reliability and future-proofing in one compact solution.
