Dedicated Loop, Hot Water Recirculation System Inspection Gallery
A hot water recirculating system is a way to bring hot water directly to the faucet when needed, and if it goes unused, it gets returned to the hot water heater. A recirculating pump is installed in the plumbing lines to create a loop that slowly and constantly circulates the water in the hot water pipes back into the water heater for reheating.

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.

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.

Installing an Instant Hot Water Recirculating System
1. A switch or motion sensor located near each fixture activates an energy-efficient circulation pump. 2. The pump houses a temperature sensor and a check valve that prevents water from entering the return line. The pump moves water that's sitting in the line back to the water heater.

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.
How To Design Hot Water Recirculation Systems
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.

Domestic Hot Water Recirculation System MEP Academy
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.

The video below demonstrates how simple it is to design a hot water recirculation system using h2x, and includes the following: How to Set Calculation Parameters Insulation type and thickness Maximum velocities Pipe materials Delta T between flow and return How to Add Hot Water Plant How to Draw Pipes and Set Pipe Heights
Best Hot Water Recirculating Pumps of 2021 Guide]
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.
How Does A Hot Water Recirculating Pump Work Domestic Hot Water
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.

There are major benefits to single-pipe heat-traced hot water distribution systems: 1. Energy efficiency: Single-pipe, heat-traced systems have third-party proven energy savings of up to 16% versus recirculation systems and may be eligible for LEED points for Energy Savings and Innovation in Design.Electrification, sustainability and decarbonization all are growing trends.

February 6, 2017. Ron George. Domestic hot water systems have been installed in buildings for many years dating back to ancient times. Recirculating hot water systems are not quite that old. Gravity hot water circulation began in the U.S. in the late 1870s, right after plumbing moved indoors. During the early years, water and space heating was.
