Abstract
A heater, in particular a motor vehicle heater, has a muffler insert in the exhaust gas outlet, a muffler insert that reduces, in particular, disturbing, low-frequency combustion noises. With the aid of the muffler insert, the exhaust gas stream in the area of the exhaust gas outlet of the heater is divided into at least two partial streams. The muffler insert can be made as a sheet metal part having hollow bodies that are made of pipe pieces. Alternatively, the muffler insert can be made as a one-piece cast part.
