The Kospel EKCO.MN3-04/06/08.PL is a wall-mounted electric central heating boiler. It features an outdoor temperature controller that automatically responds to temperature changes and allows daily and weekly programming of the room temperature. It regulates the water temperature in the domestic hot water tank and activates the circulation pump according to daily and weekly schedules.

It is compatible with central heating systems and a domestic hot water heat exchanger. It includes a circulation pump, an approximately 5 l diaphragm expansion vessel and safety components.
