How many pipes are used for rural bungalow 5 1 water and geothermal?

You can set 1 group according to an ellipse with a length of 4m and a width of 1m, and then arrange 4-5 groups of geothermal pipes on an area of 5 1m2 to configure 4-5 groups of water separators with joints. The number of pipes is about 1 group of 20m. The boiler power is 5 kilowatts. Small manufacturers have no kilowatts of boilers, so I will give you an area code. You can choose a 65-80 square meter cooker.
