About Heat Check
Heat Check - Sebastian Lehmann is an engineering and energy consulting office founded in 2024 in Herford. The sole proprietorship offers engineering services for heat transfer oil systems (thermal oil), including hydraulic concepts for heat transport, concepts for waste heat reduction, optimisation of circulation pumps, energy-saving concepts with thermal insulation and heat exchangers, as well as system concepts for new installations. Further topics include the electrification of heat generation via electric heaters as replacement or redundancy, the preparation of tender documents, support with the award process, and project management. As a listed Energy Efficiency Expert (EEE), energy consulting is also provided for non-residential buildings (DIN 18599, DIN EN 16247 energy audit) and residential buildings, including energy performance certificates, individual renovation roadmaps, heating load calculations according to DIN EN 12831, hydraulic balancing, and funding programme advisory (BEG, EEW, KFN, WEF). Owner Sebastian Lehmann previously worked as a project engineer and head of the project department at a manufacturer of heat transfer systems (HTT energy GmbH) and is a specialist for heat transfer oil systems according to DIN 4754-1-3. Clients include commercial businesses, municipalities, private households, and industry operators of heat transfer oil systems.
