The main switch of the property is 40.

It's not about changing the road. Your open circuit design is only 32A, so your indoor capacity has been determined. Even if you change the indoor switch yourself, the outdoor meter will still trip when it is on. If everyone does this, the main power supply of the unit will be unbearable and will burn out or trip. It is not recommended to do so. You can apply to the power supply bureau for expansion.

Furthermore, your floor heating should be electric heating, so one kilowatt is nearly 8 years of current. After start-up, the full-load work will reach 56A, even if other energy-saving measures are taken in time, it will not be less than 40A. How to use other appliances in your room?
