Small but strong, fireplace boiler, tiled stove heating, tiled stove heatings by Brunner GmbH

Small and strong, fireplace boiler, tiled stove heating and tiled stove heatings by Brunner It’s not always about the size, when you are planning your water- bearing device. Our HKD 2.2k-SK can be directly connected to your chimney and does not need a reheating surface. You can set it up anywhere.

Our small and strong one is our smallest device with a constant hot water content of 60-65%, due to our fin- type heat exchanger. One more advantage: it does not have to be cleaned too often!

The fin-type heat exchangers

The design of the fin-type heat exchanger can be applied to the fireplace boilers and the HDK 2.2k-SK. The fins are attached around the heat exchanger pipes, which significantly increase the active heat exchange surface. One more advantage is the time you save on not having to clean it too often, because the fins are self-cleaning due to the high temperature on their surface.
