Masonry Heaters Overview

Kachelofens? Grundofens? Putzofens? What do these words all have in common?

They’re German for stove. Sometimes called masonry stoves, they are the traditional fireplaces of Northern Europe. Refined over centuries to burn clean and efficient while keeping your haus warm and bright all through the nacht.

Our masonry heater designs use a high temperature (refractory) core with finish material (veneers) according to regional tradition or to the customer’s taste.  Smoke moves from fire and into the chimney, absorbing the maximum heat from the fire, gradually releasing the energy into your home as radiant heat. We have mastered this technology, using our proprietary refractory mix, the only North American mix specifically designed for masonry heaters.  (Shown: our Envirotech Radiant Fireplace-the Classic Grundofen.)
