Abstract: A panel comprising a heat providing layer is presented. The panel includes panel coupling means arranged for coupling the panel to adjacent panels. In order to provide heat, longitudinal grooves are arranged in the panel along the whole length of the panel. Electrical end connectors are arranged in the longitudinal grooves to protrude from at least one end side of the panel. The electrical end connectors are arranged for being electrically connected to the heat providing layer, and for being electrically connectable to at least one corresponding end connector of at least one adjacent panel, and for being at least partly resilient, thereby providing a connecting force Fcon being essentially perpendicular to the at least one of the first and the second end sides when the panel is coupled to at least one adjacent panel, and being directed towards at least one corresponding end connector of the at least one adjacent panel.

Abstract: A panel comprising a heat providing layer is presented. The panel includes panel coupling means arranged for coupling the panel to adjacent panels. Longitudinal grooves are arranged in the panel along the whole length of the panel. In order to provide heat, at least one electrical end connector is arranged at one or more end panel coupling means. The electrical end connectors are arranged for being electrically connected to the heat providing layer, for being at least partly electrically conductive, and for at least partly protruding from the one or more end panel coupling means, thereby providing an electrical connection between the heat providing layer of the panel and a corresponding heat providing layer of at least one adjacent panel coupled to the panel. The invention also concerns a heating system comprising such a panel, the electrical end connector, and a method for installing such a heating system.
