Brief review of Technova-Kobe study (2008-2015) on anomalous heat effects (AHE) by interaction of nano-metals and D(H)-gas is presented in three parts. Part-I) D(H) isotopic effect by twin gas loading and calorimetry at room temperature is reviewed. Part-II) AHE by interaction of binary Ni-based nano-metals and H(D)-gas at 200-300 deg C is reviewed. Part-III) Theoretical explanation by advanced TSC-models is briefly reviewed. AHE at room temperature was significant only in dynamic evolution of D-absorption, cf. H-absorption, and considerable D(H)-isotopic effect for integrated heat values. AHE lasting for several days has been observed at elevated temperatures in the range of 200-300 deg C. AHE has been confirmed by repeated observation of excess heat-power. AHE was lasting for long time span as several days for CNS, PNZ and CNZ samples. AHE has been seen after D(H) loading ratios saturated. AHE is therefore some catalytic surface sited effect by in/out of D(H)-gas. Observed long lasting heat gave order of GJ/mol-H(D) (or several keV/atom-H(D)) in a few days span. Level is not of H(D) chemical absorption energy, so far. AHE at 200-300 deg C is almost impossible to explain by known chemical reactions. Pd-only nano-metals did not work at higher temperatures than 100 deg C. AHE were observed both for H- and D-charging at 200-300 deg C.
