Gas is dangerous, not safe. It is recommended to use instantaneous electric water heaters. I have used the electric water heater for a long time, the quality is good, it is hot when it is opened, and the most important thing is that it is safe and energy-saving, and it is guaranteed nationwide. It is recommended not to buy those two or three hundred, which are very unreliable.

10 to 12 liters, it is enough to use. The effect is not obvious when it is large.
It still depends on the specific situation of the landlord's house, such as the house type, how many square meters, etc. >>>More
It's not expensive, it's low to mid-price.
Use a small kitchen treasure in the kitchen, and use a gas water heater or electric water heater in the bathroom. Because the distance is too long, if you use a water heater, the cold water in the water pipe will have to be stored for a long time, especially in winter.
This requirement is not very reasonable, usually 3 bedrooms and 2 living rooms of the unit, the area is about 130, your villa is only 100 square meters, but also to arrange the internal stairs, it seems too tight, and the design of the villa, the first floor is often the design of public activity space, such as living room, chess room, worker room, so the requirement of 100 square meters of three bedrooms and two living rooms of the villa itself is not very reasonable, give a villa floor plan for reference:
Nothing to prevent.
