Hot Water Recirculation Design? Using the suggestions above, our example will require a pump for 8 GPM. Since the BTUH loss of the system remains at 25,200 BTUH, the temperature drop at the end of the farthest fixture would be 6.3°F rather than 10°F. This means the water will be warmer for the first person to open the faucet.


What are Hot Water Recirculating Pumps?

described in "Hot Water Circulation Systems" in Plumbing Engineering Design Handbook—Volume 2, Chapter 6—Domestic Water Heating Systems. Actual service conditions (e.g. surge pressures, water quality, installation methods, use patterns, localized stresses) can affect the service life of the PEX.

Designing a domestic hot water recirculation system is not typically difficult. In fact, we see the exact same model recirculation pump used in application after application without incident, as this one pump is typically able to meet the minor head and flow requirements of most recirculation systems.

Hot water recirculation systems provide near-instant hot water access, so you don't have to wait for the water to heat every time you use a faucet or appliance. A hot water recirculation system creates a loop between the water heater and the faucet, and unused water quickly loops back for reheating.

Step 1 - What is a hot water recirculation system? Lets start with understanding the basics of hot water recirculation systems. Have you ever waited a long time for hot water to come out of the tap? It is likely that the long wait is because the building has a dead-leg hot water system.


Domestic Hot Water Recirculation Diagram

The whole idea of a "recirc" system is to provide hot water quickly to the person at the fixture. When water moves through the hot water piping system, it loses heat to the space through the insulation or pipe wall if no insulation. If there is no demand or flow rate in the piping system, the water will eventually drop to the ambient temperature.


Domestic hot water recirculation system design for a commercial

Hot water recirculating system. A dedicated return line is installed that connects the furthest hot water fixture in the home back to the water heater. This line allows hot water to circulate continuously back to the water heater in a continuous loop. A recirculation pump is installed on the hot water return line, typically near the water.


How To Design Hot Water Recirculation Systems

The key to proper water heating system design is to correctly identify the quantity, temperature and time characteristics of the hot water requirement. The goal is to reduce hot water wait time to 10 seconds or less, which is considered acceptable for public lavatories.


How Does A Hot Water Recirculating System Work Design Talk

Adding a return line to the domestic hot-water system creates a closed-loop path that allows the water to circulate back to the water-heating source to keep the lines warm when fixtures and other loads are not in use.
