Creating the loop is fairly easy however, doing so in a way that doesn’t waste a lot of energy is a little trickier.Ī continuously operating pump is clearly wasteful. Different types of circulation systemsĪ hot-water loop uses a small pump to circulate hot water between a water heater and a distant bathroom or kitchen. While this solution isn’t cheap, a well-designed hot-water circulation system will save energy, save water, and make your life a little more convenient.

In the latter case, the buffer tank is usually installed in series with the existing water heater.įinally, if you don’t relish the thought of having two water heaters, you may want to install a pump to circulate hot water from your water heater to your most distant fixture.

pipe.”Īnother possible solution is installing a second water heater closer to the distant fixtures- either a large independent water heater or a small buffer tank to handle a limited load until the water from the distant heater arrives. pipe, and six times as long in 1-in.-dia. pipe, three times as long in 3⁄4-in.-dia. pipe at a given flow rate, it takes roughly 1-1⁄2 times as long in 1⁄2-in.-dia. A warning, however: If you reduce the tubing size too much, the flow rate can suffer.) As Gary Klein, an energy consultant and hot-water specialist, points out, “Compared to the time it takes hot water to arrive in 3⁄8-in.-dia. tubing can be used to serve a single lavatory, while 1⁄2-in. The second step is to reduce the diameter of the pipe from the water heater to the fixture. The first step is to insulate all your hot-water pipes. You can reduce your wait time for hot water in several ways. James Lutz, a research associate supervisor at Lawrence Berkeley National Laboratory, concludes that due to the long-wait problem, “about 20% of total hot-water use in single-family residences seems to be wasted.” The cost of the wasted water and the energy required to heat it ranges from $33 to $193 per household per year the lower end of the range applies to families that don’t use much hot water (especially those with a natural-gas water heater), and the upper end applies to high-use families with an electric water heater. away from the water heater-a layout that basically guarantees a long wait. However, if you live in a stretched-out single-story home and the water heater is located in an attached garage, your bathroom may be 50 ft. If you live in a compact house and the water heater is located in the center of the basement, you may not have this problem. To top it all off, new low-flow fixtures ensure that wait times are longer than ever.

Several factors have conspired to make this problem worse in recent years: Our houses are bigger, we’re installing more fixtures and appliances that use hot water, and the plumbing code is mandating larger-diameter pipes.

Further, the analysis highlighted that some correlations exist between topological and energy metrics although more studies are required.We’re all familiar with the long wait: You turn on a hot-water faucet and have to wait a full two minutes for the hot water to arrive. The comparison highlighted some network peculiarities, in terms of topology and energy, and, consequently, the possibility to define a range of similarity to build hypothetical benchmark networks. In this paper, four existing networks and two literature networks have been compared using several of these metrics trying to identify general features of this type of civil infrastructural networks. Recently, novel topologic and energy metrics have been proposed for water distribution network analysis, design and partitioning. This general design approach, that lacks a systematic reliability based procedure, has been followed for decades in existing networks. This aim is achieved by designing them with many inter-connected closed loops and with pipe diameters that are larger than the ones strictly necessary to fulfil the design pressure at the network nodes. Water Distribution Systems (WDS) are traditionally built with topological and energy redundancy to improve network reliability against mechanical and hydraulic failure.
