Title:
SYSTEM FOR PRODUCING HEAT FOR DOMESTIC HOT WATER OR CENTRAL HEATING
Document Type and Number:
WIPO Patent Application WO/2022/172865
Kind Code:
A1
Abstract:
The present application relates to a system (100) for producing domestic hot water and heat for central heating comprising a heat generator (1) for obtaining heat from a heat source, the heat generator (1) having a generator outlet port (1.1) and a generator return port (1.2); a central heating circuit (3) having a heating feed port (3.1) and a heating return port (3.2); a tank (11) having a top portion and a bottom portion, the tank (11) containing a heat storing medium (12); a first tapping coil (7) immersed in the heat storing medium (12) in the bottom portion of the tank (11); a second tapping coil (6) immersed in the heat storing medium (12) in the top portion of the tank (11); and means (8, 9, 13, 14) to warm up domestic hot water; wherein the heat generator (1), the second tapping coil (6), the central heating circuit (3), and the first tapping coil (7) are fluidly connected in series so as to allow fluid to flow from the heat generator (1) via at least one of the second tapping coil (6), the central heating circuit (3), and the first tapping coil (7) back to the heat generator (1); the system (100) further comprising a first three-way valve (2) fluidly connected to the generator outlet port (1.1), the second tapping coil (6), and the heating feed port (3.1) and configured to selectively let the fluid bypass, or flow through, the second tapping coil (6); a second three-way valve (4) fluidly connected to the heating feed port (3.1) and the heating return port (3.2) and configured to selectively let the fluid bypass, or flow through, the central heating circuit (3); and a third three-way valve (5) fluidly connected to the first tapping coil (7) and the generator return port (1.2) and configured to selectively let the fluid bypass, or flow through, the first tapping coil (7).
