I have 70 tubes of the heat pipe version, vertical tubes. This is much different than your set up but yes, they will boil water in a big hurry also. I was dumping heat today when my tank hit my set high of 160 deg F. about 2:00 pm. I'm running the pumps and controller off batteries being charged by my voltaic panels and wind besides, that is the icing on the cake. Thanks for your information and photos. Dave B.
