Accumulation rings and half-rings

To get even better use out of the heat from a fireplace stove, you can replace the chimney with an accumulation ring or lay half-rings around the chimney. These rings accumulate heat from the fireplace liner or the stone and transfer it into living areas for as long as possible via uniform radiation. They also lower the temperature and the volume of flue gases; but above all, they utilize residual heat.

Mixtures

Here’s a look at the properties of the mixtures that we typically use when manufacturing accumulation rings and half-rings:

KZB 3
KZB 2

Centre ring—flue gases run through this ring, and heat accumulates in the refractory concrete

Ring-adapter—used for connecting a ring set to a fireplace liner or a chimney

A ring set after connection

A half-ring used for lining a chimney

We also produce a glazed version in black and in white

A cross-stacked set of half-rings
