Receiving hot water at a delay is quite irritating. After turning the tap on you have to wait until the hot water finally arrives, in many homes this is a substantial problem, especially in those houses where there are more than one-floor levels. Sometimes this can result in delays of more than several minutes. In this case, there is no problem with the water heater; it is just the problem of the long pipe run from the heater to the faucet.
To avoid this fact, you have to keep open the tap for that long that the cold water drains out and the hot water finally arrives. This is a very important issue it is not only frustrating to wait for the hot water to come but while draining all the cold water, the water also gets drained out and wasted.
The perfect solution to it
So, what is the solution to this? People have come up with an innovative idea of hot water recirculation through the appliance called hot water recirculating pump. It is a very simple way and works like: the plumber comes and installs a “T” inside the walls just behind the tap. The “T” is attached to a branch of the pipeline which is extended directly to the water heater all over through the house. A Swing check valve is attached to the water heater which is the connection point of the cold-water inlet. The purpose of this valve is very important; it helps in the prevention of the flow of water in the opposite direction.
This valve allows water to flow only I the heater. The convection current plays a very important role in this, it allows the water to flow from the heater through the pipeline and directly reach the faucet in no time bypass all over through the house. This is a continuous circle where the hot water rotates from the heater to the different outlet points and again back to the heater. This circulation of water is done by the pump and process is called hot water recirculation.
Now you might be wondering what is convection current? So, let me tell you, it is just a simple physics where it is stated that if there is a temperature difference of seven-degree Fahrenheit in the entire system then the water will move. When the water is hot it becomes lighter and wants to rise up.
What is recommended in big houses?
In big houses, it is recommended to use more than one recirculation pipes. As the number of circulation pipes increases in a large area, the water will reach faster to the faucet. Some people believe that it is mandatory to install the pump, but it is not necessary. It will increase the total costing but it will also help in quick supply of water as it is done mechanically were as not depending on the natural convection current. Thus, hot water recirculation is one of the most important things that must be done in a house to get 24 hours supply of hot water without any delay.
