All KWB hot water storage systems represent the highest quality. Using a KWB hot water storage system enables better utilisation of the fuel energy (higher annual efficiency). The heating system has fewer start-up and shutdown phases, which results in lower fuel consumption. The combination of heating system and hot water storage ensures the perfect total solution in your boiler room.



KWB EmpaCompact Stratification Storage Tank

The KWB EmpaCompact is a ready-to-connect stratified storage tank, the ideal storage solution for your boiler room. A buffer tank with a strata charging device, hygienic domestic hot water preparation, operation of low-temperature and high-temperature heating circuits, and charging of the storage tank with solar energy are united here in one system.
As a result, virtually the entire boiler room installation can be accommodated in a surface area of just 1 m². This also reduces the installation work for the heating engineer – which saves money.

Available in the following sizes: 825, 1000 and 1500 litres



KWB EmpaEco and KWB EmpaEco solar buffer tanks

The KWB EmpaEco buffer tank is the ideal complement to the KWB Classicfire log wood heating system. It can also be used in combination with the KWB Easyfire wood pellet heating system and the KWB Multifire wood chip and wood pellet heating system.
The main job of the buffer tank is to compensate fluctuations as well as to supply heat when the heating system is shut down. If a solar system is integrated, KWB provides the KWB EmpaEco Solar buffer tank. The solar heat is transferred to the buffer tank water via a bare-tube heat exchanger.

KWB EmpaEco is available in the following sizes: 800, 825, 1000 and 1500 litres
KWB Empa Eco Solar is available in the following sizes: 1000 and 1500 litres



KWB EmpaTherm and KWB EmpaTherm Solar DHWC

The KWB EmpaTherm Solar DHWC has been specially designed for the combination of solar systems and biomass heating systems.
Since biomass heating systems have longer start-up times in comparison to fossil-fuel heating systems, the heating register was put further down into the lower part of the storage tank for this system so that more domestic water can be heated by the biomass heating system .

Available in the sizes: 300 and 500 litres

Les systèmes à accumulation assurent que votre installation de chauffage soit performante et à faibles émissions, mette de l'eau chaude sanitaire à disposition et chauffe les pièces. Un ballon à stratification remplit toutes ces exigences de manière compacte et performante dans un seul appareil. Les ballons à stratification sont équipés de plusieurs zones de température. L'eau est stratifiée en fonction de sa température, dans la zone de température correspondante du ballon à stratification. Un rendement énergétique maximal et de faibles frais d'exploitation deviennent réalité.
