Stop in for a cup of coffee

They just need a boiler, that can blow up.....No problem that I can see.....:lol:
Except it can’t. Each radiator is individually vented with a pressure relief valve in addition to the one on the boiler, so overpressure on the main boiler will never occur. Steam radiator systems are low pressure for heating..not like a high pressure steam locomotive or ship boiler for generating power for movement.

Worst it will do is run out of water for steam.
