An electric surface heating structure is provided. The electric surface heating structure includes a building structural unit, contacts, electrical wire and power source. The building structural unit consists of a post-hardening mixture ofwater15-30 mass % of cement or cementitious binder, 45-80 mass % of aggregates being an electrically conductive aggregate and a non-conductive aggregate, 0.5-10 mass % of semiconductor and carbon-based aggregates, 2-10 mass % of fibrous material, 0.1-5 mass % of an admixtures which improves the processing and/or the mechanical properties. A method for producing an electric surface heating structure is provided. A post-hardening mixture of water, 15-30 mass % cement, 45-80 mass % aggregates and 2-10 mass % fibrous material is produced. 0.5-10 mass % of semiconductor and carbon-based aggregates are added to the mixture before post-consolidation, a post-hardening building structural unit is formed by spreading or pouring the mixture into a formwork and contacts.

Integrated circuit dies, systems, devices, and techniques, are described herein related to embedding a thermal solution into an integrated circuit die to heat the integrated circuit die when deployed in sub-zero environments, techniques for operating the thermal solution in a system, and techniques for fabricating the embedded thermal solution. The thermal solution includes a resistive heating element having the same material and substantially coplanar with components of devices of the integrated circuit die.

Spa systems may be used all year round and in colder weather provide an enjoyable experience for users through the cold ambient outdoor temperature and the heated water of the spa. However, failures in respect of the water circulating pump and/or heater of the spa system either mechanically, electrically or through overall power outages mean the water in the spa system and its pipework can easily freeze if ambient conditions are cold enough leading to cracks in the spa system or pipes and hence leaks when the water thaws requiring costly repair or replacement of components or entire systems. Accordingly, a freeze protection system is provided that uses a backup thermal management system discretely or in combination with other backup systems. These freeze protection systems offering backup when mechanical failures, electrical failures etc. arise by providing thermal input to the spa system through alternate thermal paths and providing alarms.

A modular platform electric trench heater is provided. The electric trench heater has a case having a first end and a second end, an electrical heating unit disposed in the case and designed to generate heat and create an upward convection current therethrough, a baffle dividing the case in a longitudinal direction into a first portion and a second portion, wherein the baffle is designed to direct the upward convection current from the first portion of the case to the second portion of the case, and a connecting unit provided in the form of a connecting plate and a plate fixing mechanism that couples the connecting plate to the first end of the case.

Thermal storage units may comprise a substrate and one or more optional coatings configured to, for example, protect the substrate from, for example, corrosive environments, increase the thermal and/or chemical stability of the substrate and/or coating layers. The substrates may comprise silicon carbide and/or a composite material and may be configured to be resistively heated to temperatures within a range of 1000-2000 C. Heated thermal storage units may be exposed to a flow of heat transfer fluid that may absorb heat from the thermal storage units and, once heated, the flow of heat transfer fluid may be directed to industrial process equipment to provide heat thereto.
