Abstract

A vehicle heater with a burner, a fan for the combustion air to be fed to the burner, a heat exchanger for heating the engines's cooling water, which is circulated in a closed circuit, and with a control device. A basic housing is provided substantially in the form of one of a parallelepiped and a semicylinder with an essentially flat, continuous upper housing surface. The basic housing is axially divided into a first housing end section, which is located at a first end and accommodates the burner and the heat exchanger, a middle housing part containing the fan, as well as a second housing end section comprising the control device. The inlet and outlet connections of the heat exchanger as well as a connecting branch for fuel to be fed to the burner are located within the upper surface of the basic housing. An attachment-type housing with at least one circulating pump for the cooling water to be heated can be attached essentially to the entire upper housing surface of the basic housing to form one of an approximately parallelepipedic or cylindrical overall housing. Also a cover can be attached essentially to the entire upper housing surface of the basic housing if the attachment-typ…
