The distance between the water heater and the water point (faucet, shower) is too long. Every time before using hot water, a lot of cold water needs to be drained. How to solve it? If you ask this question to a water heater seller, most likely they will recommend that you buy a zero-cold water gas water heater.
But let me tell you from my own experience: Don’t buy it! Not to mention the high price of this thing, the key is that you can afford it but not use it. If you buy it home, it is also used as a decoration.
Affordable and affordable zero-cold water
How does a zero-cold water gas water heater achieve "no need to put in cold water, but hot water directly"? The answer is looping.
The reason why you need to drain some cold water every time you use the water heater is because the water in the hot water pipe between the water point and the water heater is cold. Zero cold water gas water heater has a circulation pump installed inside. Before using water, the circulation pump is started to pressurize the pipes, inject the cold water in the hot water pipes into the water heater to reheat, and let the heated hot water fill the pipes.
This approach will cause a big problem: the cost is too high!
During the circulation process of the zero cold water gas water heater, even if we do not use hot water, it is still heating continuously. I believe that many people buy zero-cold water gas water heaters to save water bills. However, although the water bills are saved, the gas bills are increased a lot.
Take a look at the people who have actually bought zero cold water gas water heaters. How many people are willing to buy but not willing to use them? The high-end products you buy for home at high prices are reduced to decorations due to the cost of use.
Two more useful solutions
Since the zero cold water gas water heater is not easy to use, is there any better solution? The answer is yes, and there are more than one set.
Solution 1. Instant hot kitchen treasure
Why do we need zero cold water gas water heater? It must be because the distance between the water point and the water heater is too far, the hot water pipe is too long, and too much cold water needs to be drained.
Let’s take a look at the characteristics of remote water points: When the water heater is installed in the bathroom, the kitchen and balcony are all remote water points. These two rooms use water and have a common characteristic - the water consumption is small but the frequency is high.
At this time, you can use Xiaochubao to solve the problem. The hot water capacity of Xiaochubao is relatively small and cannot meet the needs of bathing, but it is no problem to meet the water needs of the faucet. Install a small kitchen treasure under the faucet. The distance between the pipes is less than 1 meter, and the cold water can be drained in 3 seconds.
recommends the instant-heating kitchen heater, which does not require frequent heating like the water-storage kitchen heater and saves electricity. It heats immediately. There is no water storage tank, and it is smaller in size. It does not take up space in the cupboard. It can be used on the balcony and can be hung directly on the wall. The instant-heating kitchen treasures all have water emitted in multiple directions. Either above or below the faucet.
Solution 2. Intelligent circulation system
The person said, I use a gas water heater installed in the kitchen, and I want to avoid running cold water when taking a shower. What should I do? At this time, you can consider the intelligent circulation system.
First of all, its "zero cold water" principle is also a cycle - taking the cold water in the pipe back to the water heater for reheating; and filling the hot water pipe with hot water.
The difference is that this system uses intelligent methods to solve the two defects of zero cold water gas water heaters:
The switch of zero cold water gas water heaters can only rely on manual operation or water flow (automatically starts when water is used), while the intelligent circulation system It is controlled through human body induction - after a person enters the bathroom (or shower room), the circulation system automatically starts and stops automatically after a period of time. The cycle time of
is shorter and more precise, avoiding invalid startup and long startup.
And it’s not just gas water heaters. Electric water heaters can also be equipped with intelligent circulation systems. Compared with zero cold water gas water heaters, the use environment of this system is richer and more flexible.
