Latento is a brand that provides all-season solar thermal systems designed for domestic hot water and heating support. The core of the system is a stratified storage tank, which is engineered for high efficiency in storing solar energy, even during winter months. These tanks are constructed from polypropylene with a rigid foam core for excellent heat insulation, minimizing heat loss to as low as 2.4°C per day. The Latento systems work by using powerful stainless steel heat exchangers to heat the stored water. A key feature is the option to include a latent heat storage material in the upper part of the tank, which acts as a ‘storage turbo’ to absorb additional energy during strong solar radiation. The system operates on a continuous-flow principle, which also helps prevent the growth of legionella and bacteria. The product line includes various components such as CPC vacuum tube collectors, solar controllers, and pump assemblies, which are designed to work together cohesively. The brand offers different storage tank models like the XW hot water storage tank and the XP buffer storage tank, compatible with various heat sources including solar systems, pellet heating, and heat pumps. Latento is a brand of IVT GmbH & Co. KG, which has been in operation since 1994 and is part of the Würth Group. The products are aimed at both residential and commercial clients, distributed through trade customers like those served by Würth. The system has received awards like the German environmental ‘Blauer Engel’ for its energy efficiency.
