That sure is KISS install haha... Just move the heater around on its feet where you need it...
The HYRDONIC post in your thread really got my attention however haha... Nice install there.. Hot Water heat is very safe and quiet and doesn't pose any potentially-life-threatening-situations to deal with... Finding the right HEAT TRANSFER idea is what works best there. Of course the hot water is heated in a closed loop and will need propane or electric to keep it at a settable temp... Nothing is free haha... BTU's are BTU's I guess... Would be interesting to know how many times in a day/night the six gallon hot water heater kicks 'ON'... I think Don PIANOTUNA did a test on that sometime back...
