Why Hot Water Pump Had Been So Popular Till Now?

Posted on Apr 10, 2021

One may wonder why the hot water faucet gives cold water when the person first turn it on. This is a good question. Depending on the size of the house, here we are talking about domestic usages, one may wait a few seconds or even minutes for hot water to come. This is not only inconvenient, but wastes a lot of water for people, making waste of water inconvenient especially in places where water supply is not bounteous.

The distance hot water needs to travel is the reason why cold water comes out first. Once the faucet is on, hot water is drawn to the sink through the plumbing system. Turning it off stops the water, but doesn’t return it to the water heater, which stays in the pipes and gets cold. The next time when people 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 looks like an obvious inconvenience, but there are some solutions to this situation. One can have his plumber install a recirculation pump. A hot water recirculation pump is installed on the water heater, returning unused hot water back to the water heater. It is designed to provide hot water on demand and on request. Two Types of Recirculation Pumps are namely full recirculation pump system, and recirculation pump comfort system.


With the first one, an additional pipe that is designated for hot water is installed in the home’s plumbing. This system will create 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, therefore, when users turn on their hot water faucets, they get hot water quickly. Water is not left in the pipes to get cold and people would waste less water because they don’t have to wait.

Regarding the second one, this utilized the existing cold water pipe to send the unused water back to the water heater. 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. Such a comfort system can bring hot water quickly to areas in their home that take a long time to get hot water supply. For example, if the water is far away from their shower or kitchen, the recirculation pump will solve this problem.

In the pump industry, water pump is another component in the industry that no factory can be in lack of due to its compact size and good performance. Water pump like other pumps, are like any other commercial pumps, are the equipment that moves fluids-state substance by its mechanical action but only be specifically designed to meet the industrial applications. In the market, pumps can be categorized into three major types based on the method those pumps exploited to move the target fluids. These three types are determined by the way they move fluids, and there are direct lift, displacement, and gravity methods. That is, there are direct lift pump, displacement pump, and gravity pump. Pumps are typically operated by either typically reciprocating or rotary mechanism, and consume energy to perform mechanical work moving the object, which is a normally fluid-like substance, or say, liquid.
