  We determined the orbits and stellar parameters of three eccentric eclipsing
binaries by light curve solutions of their Kepler data. KIC 8111622 and KIC
10518735 undergo total eclipses while KIC 8196180 reveals partial eclipses. The
target components are G and K stars, excluding the primary of KIC 8196180 which
is early F star. KIC 8196180 reveals well-visible tidally-induced feature at
periastron, i.e. it is an eclipsing heartbeat star. The characteristics of the
observed periastron feature (shape, width and amplitude) confirm the
theoretical predictions. There are additional out-of-eclipse variations of KIC
8196180 with the orbital period which may be explained by spot activity of
synchronously rotating component. Besides worse visible periastron feature KIC
811162 exhibits small amplitude light variations whose period is around 2.3
times shorter than the orbital one. These oscillations were attributed to
spot(s) on asynchronously rotating component.
