Abstract

The invention provides a water heater for heating domestic water in a building and a method of heating domestic water. The water heater comprises a water reservoir for storage of water and a heat structure for heating water in the reservoir. The heat structure is adapted to extract thermal energy from air in an ambient space in which the water heater is located and to deliver energy to water in the reservoir. In that way, the contribution of room heating provided by the water heater can be reduced or eliminated completely. This improves the ability to control indoor climate and it may reduce energy consumption in the building.
