PIPING AND CONTROLS

D.WATER BOILER PIPING

1.Refer to the Water Installation Survey and Hydronics Institute Residential Hydronic Heating Installation/Design Guide for Guidance.

2.The supply and return connections should be sized to suit the system.

3.Pipe the supply and return in one of two ways as shown in Figure 3.3:

a.Pipe the supply from the top of the rear section and return to the bottom of the front section. Use the 3/4" tapping in the top of the back section for air elimination.

b.As an alternative, pipe the supply from the top of the front section and return to the bottom of the rear section. Provide air elimination means within the supply piping.

4.When the return temperature from the system will be below 150°F on oil boilers for extended periods (heat pump systems, outdoor reset, snow melt, etc.), provide piping and controls to protect the boiler from condensation. Condensation will damage the boiler and will lead to shortened boiler life and maintenance problems.

5.If using a Partner indirect fired water heater or other, see Figure 3.4 for typical piping. Also refer to additional instructions supplied with the Partner.

6.If the boiler is to be used in conjunction with a refrigeration system, the chilled medium shall be piped in parallel with boiler and proper valves applied to prevent the chilled medium from entering the boiler. Refer to Figure 3.5.

7.If the boiler is connected to heating coils located in air handling units, the boiler piping system must be equipped with flow control valves or other automatic devices to prevent gravity circulation of the boiler water during the cooling cycle.

ECT Series, EC Series specifications

The PB Heat EC Series and ECT Series represent a significant advancement in residential and commercial heating technology, providing reliable and efficient solutions for a variety of heating applications. These series are designed to meet the needs of homeowners and businesses seeking dependable heating while also prioritizing energy efficiency and comfort.

One of the standout features of the EC Series and ECT Series is their advanced engineering, which includes a range of high-efficiency boilers. These units utilize a cast iron heat exchanger that ensures excellent thermal transfer and durability. The cast iron construction is known for its longevity, enabling these boilers to withstand high temperatures and pressures, which is essential for long-term performance and reliability.

In terms of efficiency, both series feature energy-saving technologies that comply with the latest environmental standards. The EC Series, for example, boasts an impressive Annual Fuel Utilization Efficiency (AFUE) rating, indicating that a significant portion of the fuel consumed is converted into usable heat. This results in lower fuel bills and a reduced carbon footprint. The ECT Series further enhances efficiency with features like modulating burners that adjust the heat output based on demand, providing optimal comfort while minimizing energy waste.

Another notable characteristic of these series is their user-friendly controls and digital interfaces. The boilers come equipped with intuitive controls that allow homeowners to easily set and monitor their heating preferences. Many units also support advanced features, including Wi-Fi connectivity, enabling users to manage their heating systems remotely via smartphone applications.

In addition to their efficiency and user-friendly design, the PB Heat EC and ECT Series prioritize safety. These boilers incorporate multiple safety features, such as pressure relief valves and low water cut-off mechanisms, which help prevent operational hazards and ensure safe operation.

Overall, the PB Heat EC Series and ECT Series offer a robust combination of advanced heating technologies, efficiency, and safety. With their durable construction, energy-saving capabilities, and user-friendly controls, these heating solutions are ideal for those looking to invest in reliable and efficient heating systems. Whether for a residential property or a commercial facility, the EC and ECT Series stand out as exceptional choices in the modern heating landscape.
