You may not realize that you already have a recirculating system. A previous homeowner may have unplugged the pump. It is worth checking to see if you already have one, especially if you’re frustrated with the time it takes to get hot water to areas of your home. Your plumbing professional can help you locate your pump and make it functional. You can also check for it yourself near the top or bottom of your water heater.

In residential areas, it is required to limit the water flow velocity to a maximum of 8 feet per second (8 ft/s). This is because higher velocities can cause pipe erosion, increase noise, and potentially lead to pressure drops. While specific requirements may vary based on factors such as pipe material, pressure, and fluid properties, it is generally recommended to maintain a flow velocity of no more than 8 ft/s in residential areas.

Attention! Keep in mind, these are only rough calculations. To get more precise estimates, you will need to take additional variables into account, such as temperature and pipe material. With this guide, you’ll have the tools you need to optimize your pipes for maximum efficiency and performance.

We highly suggest testing your thermostatic mixing valve regularly. This article will tell you everything you need about thermostatic mixing valve testing.

When it comes to water flow in pipes, determining the capacity depends on the pipe size and water pressure. Our guide provides handy tables of approximate water flow rates based on pipe size, helping you estimate capacity quickly and easily.

With this option, an additional pipe that is designated for hot water is installed in your home’s plumbing. This system creates a loop from the water heater to the faucet and back again. The unused hot water is drawn back through this loop by the pump, so when you turn on your hot water faucets, you get hot water quickly. Water is not left in the pipes to get cold and you waste less water because you don’t have to wait.

The problem with this option is, due to hot and cold water sharing the same pipe, the water from the cold faucet may be lukewarm or take time to get cold, especially if you have a swamp cooler. Some homeowners turn their pump off in the summer to solve this problem.

Maximum Velocity in Pipe depends on the pipe material and hydraulic issues. Modern pipe materials can accomodate up to 6.0m/s.

Many pumps are designed with sensors and timers. The sensor shuts the pump off once hot water has made a complete loop. A timer allows you to control when the pump is active. You can set it to shut off automatically at night, while you’re at work, or when you’re on vacation. If your pump does not have these features, a plumbing professional can help you add them.

Hot waterrecirculating pump without return line

The distance hot water needs to travel is the reason cold water comes out first. When the faucet is on, hot water is drawn to the sink through your plumbing. Turning it off stops the water, but doesn’t return it to the water heater. It stays in the pipes and gets cold. The next time you need hot water, the cold water in the pipes has to be pushed out by fresh hot water from the water heater. The more piping between the water heater and the faucet, the more cold water there is and the longer it takes.

This is a cost effective solution for homeowners who are frustrated with the wait for hot water but are unable to install the first option. The Comfort System can bring hot water quickly to areas in your home that take a long time to get hot water.
