摘要： The present invention relates to a heating installation with a Stirling engine and Stirling-type heat pump integrated within a single pressure vessel. Two hot chambers and two cold chambers, as well as a working chamber in which a piston is mounted such that it oscillates freely, are located inside the pressure vessel. The chambers are in fluid communication with one another. A displacer is able to oscillate freely to and for between each pair of hot and cold chambers. By means of this Stirling engine of the free piston type and the Stirling heat pump integrated therewith, a low-noise, low-maintenance and highly energy-efficient heating installation is formed which has a high net efficiency (COP value between 1.5 and 2.5). The heat from the cold chamber of the Stirling engine and from the hot chamber of the Stirling heat pump part is passed to a hot water system via a first and second heat exchanger. The heat from the exhaust gases is passed to a third heat exchanger. The heat exchangers may be connected in series or partly or wholly in parallel. Preferably the burner of the installation according to the present invention has a flat heat transfer behaviour to the Stirling engine's hot end upon increasing the power input of the burner, so that it can function as an auxiliary heater upon peak load demand.
