Heat recovery-type heating device

Abstract

An object is to enable a compact and high output heat storage system to perform warm-up rapidly when a vehicle is started up, and after warm-up, to recover surplus heat that is present in a heat source in the vehicle to prepare for the next warm-up event. A heat recovery-type heating device includes: an ammonia buffer configured so as to be capable of fixing and desorbing ammonia that serves as a chemical reaction medium; and a chemical heat storage reactor provided with a chemical heat storage material that generates heat through a chemical reaction with ammonia supplied from the ammonia buffer, and that desorbs ammonia using surplus heat from a heat source and returns the ammonia to the ammonia buffer.
