Do two bathrooms share one water heater water pipe, need to be thickened?

The access pipe of the water heater only has the water inlet and the water outlet. The water outlet is generally hot water at about 70 degrees. This outlet pipe is divided into two and connected to two toilets.

Mixing valves are installed in both bathrooms. One end of the mixing valve is connected to one of the hot water pipes, and the other end is connected to the cold water pipe. The mixing valve can be connected to the shower.

Because the pipes connecting to the two bathrooms are long, it is necessary to buy a large-capacity water heater as much as possible. Every time you use the water heater, you need to drain the room temperature water in the pipe first, so when you use it, first adjust the mixing valve to the full hot water, first empty the stagnant water in the hot water pipe, and then adjust the mixing valve to a low temperature and mix cold water to a suitable temperature.

It is best to thicken a shared section of hot water pipe.

However, for gas water heater products, when set to a certain hot water temperature, the hot water output of the gas water heater is certain, and even if the diameter of the hot water pipe shared in the middle is large, the hot water output will not increase.

Therefore, the water pipe should be appropriately thickened on the premise of ensuring that the heating capacity of the gas water heater is large enough to reduce the resistance of hot water outlet as much as possible and meet the demand for hot water use.
