P-K DURATION II ™ Indirect Domestic Water Heating System ECHANICAL ONNECTIONS The P-K Duration II system is designed to provide substantial domestic hot water capacity in a 32” wide x 64” long footprint and requires four (4) piping connections to operate as seen below: A. - Page 10 P-K DURATION II ™ Indirect Domestic Water Heating System 3.4.2 Boiler Piping (Simplified) The energy source for the P-K Duration II system is hot boiler water from the hydronic system and is regulated by an electronic control valve. By default, this control valve is setup to operate as a 3-way valve since this is the recommended and preferred operating method.
- Page 11 P-K DURATION II ™ Indirect Domestic Water Heating System 3.4.3 Boiler Water Manifold Piping (Duplex Only) The Duration II Duplex unit is equipped with a Boiler Water Manifold to allow for easy installation. Below is an image which shows the manifold. The Boiler water is piped to each heat exchanger from one connection point, limiting the requirement for multiple connections, provided the same boiler water is required to feed both heat exchangers.
- Page 12 P-K DURATION II ™ Indirect Domestic Water Heating System 3.4.4 Domestic Water Piping (Simplified) The P-K Duration II system features constant recirculation on the domestic hot water piping. This circulation pump offers 3-speed operation that can be selected by the operator. Constant circulation on the domestic hot water side offers several advantages: ...
- Page 13 P-K DURATION II ™ Indirect Domestic Water Heating System 3.4.5 Example Domestic Hot Water Installation It is important to note that the P-K Duration II indirect domestic water heating system does not require a domestic water storage tank, if hot water is constantly available for the 3-way valve. If using in conjunction with a boiler, the initial call for heat takes time until the boiler operates at maximum power.
