How to get instant hot water by using a recirculating pump

hot water recirculating system

Getting hot water to faucet is always an issue for many especially in winters. The hot water takes too long in the faucet fitted on the first floor. This issue occurs mostly in winters because cold weather makes hot water difficulties in reaching the faucet. Because the pipes which carry the hot water are now colder. The question arises how we can make the reach of water faster than usual. For that, you have to look for the reasons first. Here are such reasons for the slower reach of hot water to your faucet.

  1. The water faucet or shower is far away from the heater or might be on some upper floor which makes it take a more extended period.
  2. The cold weather causing pipes to get cold is another cause of this lesser flow of water.
  3. There might be an issue in the head of the shower.
  4. The size of the diameter of the pipe can be a cause of a low flow rate. The wider the diameter, the slower the flow rate.
  5. There may be some leakage happening in the pipes. The leakage may be causing water loss as well as the mixing of cold and hot type of water.

How to solve this type of problems?

The distance of faucet and water heater

The distance between the water heater and faucet can cause the water flow to lower down. The reason of cold water coming out of the pipe is cold weather because when you turn on the faucet, the hot water travels towards the specific pipe, but when you turn it off it does not go back to the heater. The water stay there are the cold pipes, and the weather outside lowers the temperature of the water. But for every problem, there is a solution. And the solution to this problem is installing recirculating pumps. There is two option you can consider while installing a hot water recirculating pump.

Full Recirculating Pump System

An additional pipeline to be installed in the plumbing system of your house. A loop is created between the faucet and water heater and come back to it. When the faucet turns on the heater, make the water to travel to the faucet, but the fresh water comes back to the heater. Keeping the water hot and you will get hot water right after turning the faucet on. This will minimize the wastage of water as well as the time you spend on waiting for the hot water to come. Many of you wonder what it will cost a lot, as in electricity of in gas bills. They might increase the cost of electricity or gas bills by running continuously, but the answer is No.

These pumps come with sensors and timer. The sensor helps the pump to turn off when the water completes the loop, which means when it comes back to the heater. And the timer can help you decide when to turn off the heater, so it will be a great help if you are on vacation or at the office or even in the night time. It will help you a lot. Not every pup comes with the updated system but can be updated according to needs. But installing this recirculating system can be a little expensive. It may cost you money, so if you cannot bear the expense, there is another option for you.

Recirculating Pump Comfort System

This type of recirculating pump uses the existing pipes to draw the water back to the heater. This type of recirculating pumps cost less than the first one. It is a good option for the people who are tired of the wait they have to do for hot water. It can bring required water to the faucets far away from the heater. There is no requirement of additional pipe in this system. The installation of this option can cost 500-800$.

Every machinery comes with some drawbacks. One of the drawbacks is that the cold and hot water shares the same pipe, so once the hot water passes from the pipe, it may take some time to bring back the cold water, or it will make the water lukewarm. Many homeowners turn the pump off in summers to avoid this problem.

Recirculating Pump System Issues

Cold weather issue:

The cold weather makes the pipe cold, so when the water passes from the pipeline gets lower in temperature making it difficult and longer to reach the faucet.

Solution: the cold weather issue can be solved by using installations over the pipeline. The insulation will keep the hot water to keep its temperature, and it won’t be affected by the cold outside. So if the pipeline remains warm, the water flow won’t be slower.

The problem in the showerhead flow rate:

The water flow depends on the flow rate of the shower head. Because the less the flow rate, the more it requires time for the hot water to come. The flow rate is measured in GPM (Gallon Per Minute).

Solution: if the shower head you are using has the flow rate of less than 2.5 GPM, then it will take a lot for the hot water to come. You need to replace the shower with the upgraded quality of the shower head. The better shower head will allow water to flow out faster, making you wait for less for the hot water.

Size of the pipe:

The water flow also depends on the diameter of the pie. The wider the diameter, the more it takes time to travel through the pipe. The pipes use in houses ranges from ¼ inches from 2 inches. And smaller pipelines make the water flow faster.

Solution: insulation helps here too. The insulated pipes make it easy to keep the temperature according to requirement, and it does not get affected by the temperature outside.

Leakage issue:

Everything requires repair and replacement, so when the faucet or the O-rings get older, it starts leaking cold water in hot water.

Solution: replacing the O-rings with the new ones can be an option to consider to prevent the water from leaking.

The most common problem what people usually face is heater being placed far away from the faucet, so the best the solution to this problem is to install a hot water recirculating pump.
