Abstract
A plant for space heating and service-water heating, is comprised of a combination boiler and a heat pump. The boiler has a first water chamber adapted to be heated by a furnace and/or a heating insert, a second water chamber which communicates with the first chamber and which contains a heat-exchange surface for heating service water, and a third water chamber containing a heat-exchange surface (36, 36a, 38) for preheating cold service water. A circuit is connected to the third water chamber in the lowest water temperature zone, by means of which, when the heat pump is in operation, water can be fed to the condenser section of the heat pump and, after the water has heated up, be returned to the second water chamber. The third water chamber communicates at least with the second water chamber.
Claims23
A plant for space heating and service water heating, said plant comprising
- a combination boiler having a first water chamber for receiving water to be heated therein, a second water chamber communicating with said first chamber to receive heated water therefrom, a first heat-exchange surface in said second chamber for conveying a flow of service water therethrough in heat exchange relation with heated water in said second water chamber, a third water chamber in communication with at least said second water chamber to receive heated water therefrom and a second heat-exchange surface in said third water chamber connected in series with said first heat-exchange surface relative to the flow of service water for pre-heating the flow of service water;
- a heat pump having a condenser section therein for conveying a heated medium therethrough;
- and
- a circuit connected between said third water chamber, said condenser section and said second water chamber for conveying a flow of heated water from said third water chamber into heat exchange relation with the heated medium in said condensor and subsequently into said second water chamber.
A plant for space heating and service water heating, said plant comprising
- a combination boiler having a first water chamber for receiving water to be heated therein, a second water chamber communicating with said first chamber to receive heated water therefrom, a first heat-exchange surface in said second chamber being in heat exchange relation with a flow of service water;
- a third water chamber in communication with at least said second water chamber to receive heated water therefrom and a second heat-exchange surface in said third water chamber connected in series with said first heat-exchange surface relative to the flow of service water for pre-heating the flow of service water;
- a heat pump having a condenser section therein for conveying a heated medium therethrough;
- and
- a circuit connected between said third water chamber, said condenser section and said second water chamber for conveying a flow of heated water from said third water chamber into heat exchange relation with the heated medium in said condenser and subsequently into said second water chamber.
