A latent heat accumulator is disclosed including an upright container having, in a major volume first section, a latent heat storage medium, and a passage for a heat exchange medium extending through the charge in the first section. The passage is of the type of a conduit provided with intake openings at different levels. The flow of heat exchange medium through the conduit generates low pressure at the intake openings with the result that a part of the surrounding charge of the heat storage medium is drawn into the conduit for thorough intermixing and heat transfer. The intake openings are preferably protected to prevent large solidified particles of the heat storage medium from blocking the openings or from entering the conduit. The invention improves the heat transfer capacity and reduces the charge of the heat storage medium entering the associated heat exchange circulation system while retaining a relatively simple structure of the accumulator.
