Abstract

The invention relates to a heater for connection to a liquid circuit and configured to heat liquid, in particular as a back-up heater in addition to a heat pump unit, the heater comprising a tank for receiving liquid and having a tank wall extending in a longitudinal direction from a tank bottom and defining a liquid tank volume, the longitudinal direction running opposite to gravity, when the heater is installed on site, an inlet port and an outlet port for passage of liquid of the liquid circuit into and out of the tank, respectively, a heating means at least partially inside the tank for heating liquid inside the tank, the heating means extending in the longitudinal direction, and at least one hollow element provided inside the tank and extending in the longitudinal direction, a hollow element defining a liquid sub-volume and for separating the liquid sub-volume from the remaining liquid tank volume along the longitudinal direction, wherein a hollow element is in fluid communication with the remaining liquid tank volume at an opening of a hollow element, wherein the heater is configured such that the location of the opening of a hollow element, seen in the longitudinal direction, changes the passage of liquid from the inlet port or to the outlet port in the longitudinal direction, compared to the absence of a hollow element.
