Large window - a lot of warmth behind it: The solid BRUNNER kit system measonry heater "BSG" is used when no individual shapes or ground plans are provided. Although a storage heater usually needs a longer period of time to get heated up due to its mass, it is possible to enjoy the furnace warmth shortly after it is ignited - the large viewing window makes it possible. The BSG can also be planned as a waterbeating unit.
