Anyway, today is in the town, Liu Yi simply went to the place where he bought electricity last time, it is a little inconvenient to take a bath in the village, Liu Yi wants to buy a few solar water heaters this time, and it will not affect anything if they are put on the roof, and the experts and students in the university are also used to it.

Now many things are Liu Yi is busy with one hand and one foot, and many things cannot be left out and forgotten, just like the installation of water pipes this time, if it is implemented after someone moves in two days, then you have to wronged others not to use water? Isn't that funny when you think about it.

When he came to the store where he bought household appliances last time, the boss actually recognized the owner of his one-time purchase of tens of thousands of yuan, and he came forward to welcome Liu Yi very enthusiastically, which made Liu Yi feel flattered.

I heard that Liu Yi came to buy a solar water heater this time, so he introduced it to him familiarly, speaking of which the things sold at this point are really complete, and the solar water heater is still a big brand that acts as an agent for Four Seasons Muge.

After comparing parameters and prices, Liu Yi specified a water heater and said to the store owner: "Boss, is there a discount for this style of water heater in your store?" I'm going to buy a few more this time. ”

The boss looked at Liu Yi and pointed to a water heater on the product promotion page, and thought for a while: "There must be a discount for you to buy it, how many are you going to buy this time?" ”

Liu Yi stretched out 3 fingers and gestured, seeing that the boss was overjoyed, thinking that the price of the water heater that Liu Yi pointed to just now was 12,800 yuan, and his profit for each unit was very good, even if one wiped out 800 yuan, he would make a small profit.

So without hesitation, he simply replied: "If you buy 3 units, I can remove the 800 yuan and return it to you for free installation, what do you think?" ”

Liu Yi thought that this boss was also upright in business, so he nodded and replied, "Okay." I went to the bank to withdraw money, when will your water heaters be delivered to my home? ”

"Soon, I will be able to give you well this afternoon, you can rest assured, you can find me if you have any problems in three years, but you will have to charge for me in addition to the warranty period." The boss and Liu Yi said with a smile.

"This boss is really funny!" Liu Yi thought so in his heart.

Not far from here is the China Construction Bank, and Liu Yi was about to say hello to Qin Fuchuan in the past, but he heard from the bank staff that he had gone to other places to study and study.

"Damn!" Liu Yi scolded secretly, inspected and studied, and only when he said this sentence did the pig believe it. The business establishment is good. Eighty percent of Qin Da Fat is running with public funds, where to go and be happy.

After waiting for a while, Liu Yi took out 100,000 cash. The few things I did today can basically spend all the cash in the house, and I have to pay 36,000 to the owner of the store, and it is normal for Liu Yi to keep some money in his hand.

After paying the money, he took the receipt to make an appointment with the owner of the household appliances, and Liu Yi also drove back. It's not early, and his mother may be waiting for him to eat.

The afternoon's events were all piled up. I have to explain to my mother when I go back. may not be able to avoid the mother's nagging, anyway, it is just to say that some elderly topics are not sluscious and lavish.

Liu Yi can only listen to it, and then he will not fall behind what he should do, and his mother will not take these things to heart. It's just that sometimes under the influence of traditional concepts, I can't help but say a few more words, and Liu Yi is gradually adapting to it now.

Sure enough, Liu Yi, who went back, said that he went to do a few things this morning, which also concealed most of the funds spent on these things, and his mother said that Liu Yi only cared about enjoying happiness and did not have the spirit of hardship at all.

Liu Yi said to his mother while eating: "Mom, now that our family has money, we must not be reluctant to spend it, and I will wait for other people to tell me about my daughter-in-law in the future, if it is too bad, who will tell me!" ”

But Liu Yi touched his mother's moldy head at this time, and his mother glared at Liu Yi sternly: "You are embarrassed to say that you have eaten 29-year-old meals this year, and you have to find a daughter-in-law for me to come back, and take advantage of my strong body to bring you children." ”

This time, Liu Yi didn't have a temper at all, so he had to bury his head in the rice, and after a few sighs, he finished the food in the bowl, and the chopsticks were smooth. "Mom, there's a lot going on this afternoon, so I'm going to go out."

After saying that, a gust of wind ran outside, and several dogs who were eating lunch were unknown, so they also rushed outside with Liu Yi.

The mother looked at Liu Yi's figure walking away, and muttered in her mouth: "This child, how can he not grow up when he is so old, he is in a hurry, and he is in a hurry." ”

But Liu Yi couldn't hear it, and he didn't know how to feel if he heard it.

In the afternoon, the first to come were the four staff members who pressed the water pipes, and when Liu Yi explained to them how to place these PPR water supply pipes, they found that Liu Yi's house was built so magnificently and luxuriously.

Liu Yi is a little proud in his heart, everyone will be shocked by a few of his houses when they come for the first time, this is not Liu Yi's inner show, he feels that everyone is surprised to see his home when they have a kind of identification with this house, which shows that Liu Yi's taste is good.

First of all, Liu Yi led them along the road to the waterhole where the tap water was fetched, and then explained to them a little how to do those places along the way.

Liu Yi picked up the phone and listened for a while, it turned out that the workers and masters who sent the water heater to the door to install it arrived, and they were waiting for Liu Yi to go over in the small courtyard on the side of the highway at this time.

Liu Yi had no choice but to smile at the few workers who installed the water pipes, to be honest, it was enough to have a few of them, as long as each water pipe was firmly connected without seepage, Liu Yi believed that they were much better than Liu Yi as a layman for a long time.

Liu Yi and the others waited, and Liu Yi only had to wait for them to do an inspection after they got it.

When Liu Yi came to the side of the road, the three masters had already unloaded the solar water heater from the car, and everything was placed on the side of the road.

Liu Yi greeted them politely, until this time he remembered that he didn't smoke, and he also carried a pack of cigarettes in his pocket today, and at this time he smiled and tore open the seal, and each person scattered a cigarette for them and helped them light it.

Thinking about it a little funny, he forgot about it after dealing with the workers who pressed the water pipes for a while just now, and he also made a difference in treatment, and he forgot to make it up to them when it passed.

The solar water heater itself is a photothermal converter, which is different from traditional natural use, such as drying and lighting.

The vacuum tube is the core of the solar water heater, and its structure is like an elongated thermos, with a vacuum between the inner and outer layers. The surface of the inner glass tube is coated with a spectrally selective absorption coating using a special process to maximize the absorption of solar radiation energy.

After being irradiated by sunlight, photons hit the coating, solar energy is converted into heat energy, water absorbs heat from the outside of the coating, the water temperature increases, the density decreases, the hot water moves to the coating, and the cold water with a large proportion decreases. Hot water is always located in the upper part, that is, in the tank.

The heating up of hot water in a solar water heater has little to do with the outside temperature, and mainly depends on the light. When you turn on any of the faucets in the kitchen or bathroom, the hot water in the water heater will flow out by the natural drop, and the larger the drop, the higher the water pressure.

Today's solar water heaters are still stained with high technology, but the structure is very convenient to install, which is why it is loved by people all over the country.

Liu Yi went to Yunnan once where the light was strong, and almost every house was covered with all kinds of solar water heaters on the roof, which gave Liu Yi a great shock at that time, so there was no solar water heater after returning to the village this time, so I felt that the sun was very precious, and it could bring great convenience to the villagers.

The three solar water heaters only took three workers and one and a half hours, which is still one of these three installed in different places, two in the roadside courtyard, and can be used separately if there are many people in the future, otherwise it may not be enough.

But there is no water source in the roadside courtyard, and the water heater can't be tried. Fortunately, the pretence is very simple, and several masters told Liu Yi about some of the usual use and maintenance when they tested the water heater here in Qingyouju.

Waiting for the water heater to operate normally, when the mother can use the hot water downstairs, the masters can say goodbye with peace of mind and leave a phone once the two water heaters in the roadside courtyard have any problems or questions, you can find them, when necessary, they will also come to the door to debug, the after-sales work is quite in place, Liu Yi is impeccable.

Liu Yi took out a cigarette again, and each of them scattered one, and the workers were also very relaxed after the completion of the work, and soon burned like a chimney.

Bidding farewell to the workers who installed the water heater, Liu Yi came to the workers who installed the water pipes non-stop, and at this time they were also progressing very smoothly, and they had entered the final stage of construction.

This time, Liu Yi didn't forget to give them cigarettes, he lit them while apologizing, and started to do it after they finished smoking.

With Liu Yi's joining, the action immediately became faster, and Liu Yi was not lazy in them, so it took half an hour to connect all the pipes, and only the last part of the pipe was left to sink it into the pool, as long as it was completed, then according to the drop in the pipe, the mountain spring water could automatically flow into the water pipe.

As long as every water pipe is not leaked or broken, the installation will be accepted, and the half-day work of these masters will be successfully completed, and Liu Yi's installation cost will also fall into their pockets.

The phone told the mother at home to turn on all the faucets, and Liu Yi followed the master worker to slowly walk back along the water flow that had passed.

At this time, Liu Yi's phone rang again, and when he took out the mobile phone in his trouser pocket, he saw that it was actually Gu Jian calling, and now he doesn't know what Lu Dao is looking for him!

But as soon as the phone was connected, Liu Yi shouted: "What, the workers are coming over today!" (To be continued......)
