Become the city lord from today

It is not difficult to use a boiler to generate heating. It is essentially the same as boiling water in every household.

The heat energy is diffused into the room through the pipes, and then the warm air is transported out by the radiator. Liu Feng chose water vapor as the heat energy carrier because its upper temperature limit is higher.

At the same time, it is also convenient for recycling. As long as the boiler keeps burning, the steam pressure generated will make every tiny high-temperature water droplet fill every corner of the copper pipe.

Of course, steam heating is not without its shortcomings. The shortcoming is the welding between pipes. Once there are some mistakes, an explosion will occur.

Pipe explosions are no joke. As long as the ultra-high-temperature water vapor touches the skin, it will immediately burst open, just like peeling an orange peel, so Liu Feng asked the scientific research department to cooperate with the people in the workshop.

The two departments worked together to conduct tests at the same time. After testing hundreds of times, there was no problem, and the heating system was installed in the castle.

People from the scientific research department and people from the workshops inspected the castle up and down and reported,"Your Majesty, there is no big problem. You can start to put the boiler to work.""

"good."Liu Feng nodded and motioned for them to operate.

Mina looked up at the pipe and asked,"Your Majesty, I have a question."

"Um? what is the problem?"Liu Feng blinked his black eyes.

"You said that this heating relies on water vapor generated by the boiler for heating, right? Mina asked softly.

Liu Feng nodded and said doubtfully,"Yeah, what's wrong?" Mina frowned and said,"If the water in this boiler boils very hard, as the book says, the pressure in the furnace will be very high. Will it cause an explosion?""

"Hahaha......"

Liu Feng smiled heartily, but he didn't expect the cat-eared girl to think of this."This will never happen. I asked the people in the workshop to make an automatic pressure reduction method. When the pressure in the furnace is too high, The flywheel rotating at high speed will open the valve, so that the pressure can be released"

"So that's it. It seems that I was worried for nothing. How could His Majesty not have thought of this?"Mina said with a squinted smile.

As the heating system started to operate, the original thick coats in the castle changed into thin single clothes, as if it had returned to the time when autumn just entered.

With the heating system in the castle, this This is the real life of a royal family. Now the castle has electric lights, heating, fans, shower systems, etc. It can be said to be an ultra-modern life. It is simply different from those in the territory today who still fetch water for bathing, candlelight lighting, and burning charcoal for heating. It was a sharp contrast, which is why Jenny kept coming to the castle to live even though she bought a house.

Mina tied up her loose hair and said lazily,"Your Majesty, it's getting warmer."

"This makes me want to continue sleeping. Enri covered her mouth and smiled,"

With this heater, Tisi should be able to continue sleeping." Liu

Feng shook the tea cup in his hand and said gently,"It's cold and it's okay for them to sleep a little longer. There's nothing to do now anyway.""

"Knock knock knock......"

"crunch......"

Niujiao Niang opened the door to the study room, holding a plush doll in one hand, obviously not waking up.

"Your Majesty, why has the castle become so hot? I'm sweating all over."Tisi's little hand was still scratching her thigh.

Enri covered her mouth and smiled, and explained,"The heating system has just been turned on in the castle."

"Heating system?"Tis blinked her purple eyes and said.

Nicole took the stuffed toy from the Horn Girl's hand and explained,"To put it simply, the house will be very warm in winter, and your hands and feet will not be cold in the future.."

Except for Mina and Enri, the beast-eared girls will have cold hands and feet in winter, and they are also very afraid of the cold. They often stay in bed for a long time. Others like Lucy are fine.

"It turns out that it is like this, it is really great, my little skirt can be taken out and worn again."Tisi smiled heartily.

Liu Feng held his forehead and shook his head and said,"You really like that skirt, you talk about it every day."

That skirt is not an ordinary skirt. It is the skirt that Elsa wore in her final transformation in the second part of Frozen. After watching the stage play, the horn girl looked straight at that skirt.

Of course Liu Feng looked at it. The horned lady got over her idea, so she traveled back to the earth overnight, bought a genuine skirt, brought it back and placed it next to Tess's bed.

It is conceivable that the horned lady's eyes were wet with excitement the next day, and Tess, who was always bold, Si still has a lot of girlishness in her heart, and she will wear that skirt whenever she is not working.

Although the hem of the skirt is so high that it touches the floor, and the streamers also touch the floor, which makes movement very inconvenient, Niujiao Niang still can't put it down.

"Hee hee, I'm going to put it on now."Tis turned around and ran away, walking all the way back to the room.

Enri looked at the horned lady, shook her head and smiled,"That's enough, she has to stage a story about Elsa every night.

Mina shrugged and said with a smile,"She will probably come to play with us again tonight.""

Liu Feng put down the tea cup and said gently,"Don't you also like it very much? Who can sing that song in the shower? Enri wagged her fox tail in embarrassment and changed the subject,"Your Majesty, when will this heating system become more common?" Liu

Feng nodded thoughtfully and said,"There may not be a solution for the time being. If it is going to be popularized, it will probably be next year.""

"I understand, because we don’t have much copper to make pipes, so we can’t consume so much to make pipes. After all, the scientific research department still needs to use it, right?"Mina guessed

"Yes, the copper mines cannot allow us to consume them so much now, but when the mines in the Yaden Kingdom can be mined, this heating system will be popularized. Liu Feng said lightly.

Anli blinked her brown eyes and said,"I believe it won't take long.""

"Well, it's going to be soon, they should be here around the same time. Liu Feng smiled slightly
