Thx. Is it ok to add a pressure tank to the hot water system instead of using an open vent faucet? (i.e. use a regular faucet, but have a pressure tank to prevent steam pressure building up) Thx
American building codes are a bit different to the UK Building Regulations (I’m assuming you’re American as you use the term faucet). In the UK you shouldn’t expect any steam as there are a number of safety precautions that should be taken to prevent the water from exceeding 100*C (control stat, overheat stat and temperature/pressure relief valve). In most cases it’s normally okay to upgrade an open vented to sealed system as long as it’s installed to local regulations/code.
