Can anyone sugest a way for me to automacily top up a boiler as the level drops whilst generating low preasure steam.
I am building a small boiler steam generator for a sauna, my problem is that the boiler needs to be small and portable for backpacking and treking so therefore may only hold a couple of litres of water, the small tent style sauna will demand more than this. the boiler may be something simple like a kettle with a pipe attached to carry the steam into the sauna, but whilst taking a sauna i do not want to have to keep topping up the boiler, i have a constant heat source so no problems there. i also have a collapsable fold up plastic water carrier which i can suspend above the boiler as a reservoir but will need some sort of valve that allow the boiler to top up automaticlly. hope that all makes sense. thanks in anticipation.
