When planning a fireplace, the focus is always on the customer's requirements and what is feasible. In this case, however, the client wanted a fireplace system with a storage tank in which the convection function can be switched off completely so that only the heat storage tank is used as required - and this with a medium-sized fireplace insert.

At first glance, this system looks like a classic combination system. The combination of a warm air fireplace and a heat storage after-switching surface enables flexible heat design as required and desired. Convection creates rapid and direct heat via the glass and the air grilles. This heating concept ensures the desired fire enjoyment and pleasant radiant and convection heat. But what if you don't want convection heat and just want to rely on radiant heat via the storage tanks? Holger Nowatzke, the stove builder who created this ingenious system, explains how this system works and what needs to be taken into account during construction. The concept of closing the air grilles was usually used in tiled stove inserts to avoid convection. However, this often meant that the impressive flame pattern that many people appreciate was missing. In the past, it was also necessary to generate a large amount of heat. Households therefore relied on a heating or fireplace insert in addition to the basic stove. Over time, fewer and fewer wood-burning stoves were built and replaced by heating inserts with a secondary heating surface and heat storage function. As the heat requirement is now reduced in every new build or refurbishment project, but the flame pattern still needs to be retained, wood-burning stoves are increasingly being used again due to their storage capacity and pleasant radiant heat.
