Mark Brunnr wrote:The first response given to someone new to RMH and wanting to heat water with one is "BOOM-SQUISH", that being the sound of the water supply exploding due to a sudden pressure change, and your body absorbing the brunt of the force. Like, "wasn't there a cabin out here last week?" kind of force.
