ᐅ Installing a Hot Water Storage Tank for the Bathroom – Pressure Equalization?

I want to install an open (non-pressurized) hot water storage tank in the bathroom instead of a tankless water heater. There are two 1/2 inch water connections in the wall, one for hot and one for cold water; these are connected to the sink and shower. I want to connect the boiler to these connections. When the water heats up, it expands. How do I handle the pressure relief? Can I install a low-pressure faucet at the sink and cap one of the three hoses?

Hello

Non-pressurized hot water tanks are usually designed for only one outlet.

Why not use a pressurized tank?
Connect the leak water pipe, for example, to the drain of the heat exchanger.

Hello, thanks for the reply.
I have already used the pressurized boiler and cannot return it anymore.
