ABSTRACT:
A heating system utilizing a closed oil system and a friction element for heating the oil as the oil is forced through the element. The oil's path is from a storage tank through the friction element, then to the radiation units and then is returned to the storage tank. A high temperature path and a low temperature path are provided to improve comfort control.
The heating element is formed of woven stainless steel which is compressed in a mold to obtain sufficient strand density to produce a high heat of friction.
