"This thing is in a hurry, let me see how our pipes should be laid first." After Zhang Nan finished speaking, he began to look inside his mansion.

"Pipes? What do pipes have to do with heating? Cui Yue asked puzzled.

"Of course it matters, the pipe is filled with hot water and keeps flowing, and the pipe passes through the house, doesn't the room heat up?" Zhang Nan said.

After watching for a long time, Zhang Nan finally gave up the idea of laying floor heating, although the floor heating is very warm, and the heating is relatively uniform, but helplessly, although Zhang Nan's home has floor tiles, but most of them are still dirt soil, which will definitely not lay the floor heat, and the laying of floor heat is obviously much larger than the heating, so Zhang Nan finally chose to use traditional heating.

Although the pipe can't be laid in the house, Zhang Nan is also a person who can make it, anyway, get through this winter first, as for the geothermal or something, wait until the weather gets warmer, pull out the house and rebuild it.

Zhang Nan chose to choose and found that if he wanted to lay heating in his home, he could only choose the double-pipe heteroplex parallel method to lay it, and he couldn't help but require that the pipes were relatively short, and each heating could be controlled separately.

Like the physical series-parallel connection, although the series connection is simple, the biggest disadvantage is that if one place is broken, then the whole set of equipment will not be used.

After choosing the laying method, Zhang Nan began to pace back and forth in his house, and began to think about how to lay in his home without affecting the appearance and making the most of the heat energy.

Zhang Nan jumped up and down like a monkey, which also alarmed the people of the house, of course, the people didn't dare to ask Zhang Nan what was wrong, why did the old man who looked mature and stable on weekdays suddenly become like this.

"Lang Jun, what's wrong?" Li Lizhi looked at Zhang Nan, who was about to climb to the old crooked neck tree in the courtyard to observe the mansion, and asked strangely.

"Who knows? Did you know about St. Man? Li Chengxia turned her face and asked Li Chengxia, who was standing beside her.

"Where would I know, I just came back from the place where the clothes were made, this is about to enter winter, it is a good time for the new style last season, I don't look at our Yueliman, but I will lose a lot of money." Kim Sunman smiled wryly and shook his head.

Since having Yue Liman's career, several women have finally found a serious thing to do, so their energy is all focused on business.

But helplessly, Cui Yue and Li Lizhen really have no business talent, so most of Yue Liman's business is handled by Jin Shengman, except for some necessary things that need to be discussed by three women, and Jin Shengman is in charge of the rest of the time.

The garment part was also handed over to Wu Shun, who is now both the chief designer of Yue Liman and the director of Yue Liman's garment factory. It can be said that Wu Shun alone can support her mother and sister.

Because this is Zhang Nan's business, the Wu brothers don't dare to come to Wushun's trouble, and Wushun's life is naturally getting better day by day.

"Yue'er, do you know what's wrong with Lang Jun?" Jin Shengman could only twist his face to Cui Yue and asked.

"Lang Jun said that he wanted to make some kind of heating, with that thing, we don't need to make charcoal braziers in the house, and Junyan and Zhen Zhen won't catch a cold if they run around in the house." Cui Yue said.

"Is it that amazing?"

"Lang Jun said yes, that's it, I haven't seen what Lang Jun said and can't do it."

Hearing Cui Yue say this, the rest of the women also nodded in agreement, indeed, just like Cui Yue said, as long as Zhang Nan said it, there is really nothing that he can't do.

Zhang Nan waited on the tree for nearly a stick of incense before Shi Shiran climbed down the tree, Cui Yue and the other women saw that Zhang Nan finally came down from the tree, and hurriedly surrounded him.

"Lang Jun, how's it going?" Cui Yue asked hurriedly.

"Hey, don't mention it, we can't use the heating in our house." Zhang Nan also said with a look of annoyance.

"Ah, why?"

"There is a place for the pipe, but there is no place to burn this boiler." Zhang Nan also shook his head with a look of pity.

"What's a boiler?" Cui Yue was still puzzled.

"Let me tell you this, there is hot water flowing in the pipe, but this hot water needs something to heat it, so we need a big boiler to heat the water, and now there is no such big place in our house to burn the boiler, even if it is burned, I can't put the boiler room in the house." Zhang Nan said helplessly.

Now that the boiler is burned, the iron must be coal, not to mention that there is more coal burning, and the dust is floating everywhere in the house, just a safety issue, Zhang Nan will definitely be unwilling.

"Huh? Then according to Langjun, what kind of heating can't be used? Cui Yue also said with a look of pity. In fact, it doesn't matter if Cui Yue uses it or not, it is mainly for the sake of Junyan and Zhen Zhen, so Cui Yue also feels very pity.

Seeing the pity on Cui Yue's face, Zhang Nan also gritted his teeth.

"No, for the sake of our children's health, this heating must be repaired." After Zhang Nan finished speaking, he shouted: "Lao Su, prepare a name card for me, master, I want to go out to visit a few people." ”

The Chongrenfang where Zhang Nan lived was the residence of the nobles, and basically all the officials above the Li Er Dynasty lived here.

And the people Zhang Nan is going to visit are the officials who have a good relationship with him on weekdays.

"Master, it's not time yet, no one is going to anyone's mansion now." After Zhang Nan walked out, Cui Yue remembered that it was still working time, and not everyone could be as unscrupulous as Zhang Nan.

It's a pity that Cui Yue still underestimated Zhang Nan's determination to build a heater. When Zhang Nan visited the eldest grandson Wuji's mansion and found that the eldest grandson Wuji was not there, Zhang Nan went directly to the palace to find the eldest grandson Wuji.

As soon as he entered the department of the eldest grandson Wuji, Zhang Nan saw the eldest grandson Wuji and Fang Xuanling sitting on the warm kang drinking tea and looking at the excerpts.

"The two of you are very good." After Zhang Nan said hello with a smile, he began to introduce his heating business.

After a stick of incense, Zhang Nan came out of the ministry with a satisfied smile, and then Zhang Nan went directly to the military department, and with a stick of incense, Zhang Nan walked out with a satisfied smile.

That's right, what Zhang Nan does is to pull the relationship, in short, one family wants to lay out the heating, and if the boiler can't be repaired, the ten should be okay.

Zhang Nan ran from department to department, and finally attracted the attention of Comrade Li Er.
