<p>The method involves connecting a channel (21a) of a fresh water heat exchanger (21) in parallel to a storage tank. A control unit (29) is provided to control first and second circulator pumps (22, 23), such that mass flow of a heat transport medium through a heat source (20) i.e. condensing gas boiler, is greater than mass flow of the heat transport medium through the channel in an operational state. The mass flow of the heat transport medium through the heat source is smaller than the mass flow of the heat transport medium through the channel in another operational state. An independent claim is also included for an apparatus for heating fresh water and providing heat for a building.</p> |
