Hot-Water Recirculation System
It’s basically a plumbing system that sends hot water into the fixtures. Today, it is considered to be the most advanced plumbing tactics. It has been designed by the renowned plumber Dave Yates who named it as the basic yet important household plumbing system that every home must have. The system has brought comfort to lives with the technology embedded in it, especially when there’re winters knocking the doors.
What are the benefits of Hot Water Recirculation System?
How would you feel, you are taking a bath, you turned on the tap but you have to wait 2-3 minutes to let the hot water to fall out of it? Sounds Weird? Right? Obviously, in the world we are, technology has modified our lives to more than 80% then why to wait? Doubtlessly, every one of us needs water to run from a tap in less than 10 seconds. This is what actually your hot water recirculation pump provides you. It also offers you a long life when you choose right hardware, pumps, and controls.
This advanced and efficient system is cost-effective; it requires less energy to work, hence it saves water and utility costs to great extent. It also saves lukewarm water to be dumped down rather it passes it to a cold water line.
Up till now, in most areas, residents complain about the shortage of fresh water, if you are facing the same issue, you certainly need to opt with Hot water recirculation system. Experts have researched in several different ways to see how much water is saved by this plumbing system and they concluded that it can save from 12,000 gallons to 15,000 gallons yearly. The system has been introduced to more than 60% of the US areas to cope with fresh water shortage. Experts say that saving of water depends on the quality and sizes of the pipes that are being used for hot water recirculation.
System components of the hot water recirculation system
Below are some components that help hot water recirculation system to progress well.
- Hot water recirculation:
If in the condition the return pump is not working on the proper terms, the pipeline of hot water gets cold until some hot water is not drawn in it. It is designed for the purpose to cycle around the pump on and off that is completely based on the return water temperature settings.

- Check valves:
A check valve whether it is open or closed can lead to so many issues. It can create some bigger issues if it is part of the HWR system. Any check valve that is stuck closed can somehow overheat and can also potentially fail the circulation. You can make the use of spring loaded check valves at the time of mounting in vertical positioning, and it can be installed in horizontal direction too.
- Gas Supply:
It is much important to have a check over the value of gas and also the pressure supply of the gas too. Each single gas water heater will be indicating the approximate supply and pressure on top of the rating plate.
In so many conditions, it is just because of the venting system that shutdown can take place. If the vent is not coming to be compatible with the functioning of the heater, it might get corrode or condensed. If the vent system goes under sizing condition, it can lead to the result of some back drafting or some flame roll out.
Cost Analysis of Hot Water Recirculation System
The category of Recirculation pumps is mostly available using permanent split capacitor (PSC) motors. They are also settled with the electronically commutated motors (ECM) as well as with electronic controls along with permanent magnet Vortex pumps. Normally recirculation pumps with the built-in control functions can run for around 4 minutes an hour maximum. It is therefore wise enough to stay with easy to follow PSC-pump-driven motor. ECM motors are put into the requirement of electronic control with a wide range of other parts.
- The approximate cost of electricity is $0.12 as per kW for the small pump in favor of around 250 feet of pipe on the timer.
- It works eight hours the whole day with the use of sensor and switch that mostly runs on the average time of three minutes in one hour. This makes it cost around $1.40 to $1.59 per year in the range of electricity.
- The course of .79-amp circulator makes the use of around 90 watts. It has the cost of $4.73 as per year.
As the consumption of power has been much small, therefore PSC pump is the best selection. It has the features of being durable, and stronger in resistance and much easier with its service access. The category of tankless heaters will require the flow of around 0.5 to 1.1 gpm to turn the heater on when the temperature will reach its set point.
Types of Recirculation Pumps
- Full Recirculating Pump System:
Right through this option, some extra pipeline is installed in your home that is meant for some hot water designation. This system will be effective enough in creating a loop from the side of the water heater to the side of the faucet and then get back again to its place. This unused water is drawn back straight into the loop by the use of a pump.
There are so many pumps that are designed with the use of some timers and sensors. This sensor will be accountable as in shutting the pump off as soon as the hot water completes the entire loop. The timer will let you control the time capacity when the pump is active much. Shut it off at the night time.
- Recirculating Pump Comfort System:
The second type on our list is the recirculation pump comfort system! In this system, some sort of old cold water pipeline will be used to send the unused water back to the side of the water heater. This can turn around much cost effective for the homeowners.
It has the system through which hot water quickly gets into the areas of the home that are somewhere taking a long time to get the hot water access. You do not need to install any kind of extra pipes in this system. These pumps cost you around $500 – $800 range.
