Filling with water

To fill with water, install a decorative faucet. Be sure to arrange a “bottom point” where the water will drain from the system when the tank is idle in the cold.


It is necessary to take into account where the splashed water will flow so that it does not flood the furnace, in winter it should not accumulate and freeze.
