Thanks for the info i guess that i found out for my self today how hot the water gets coming out of the hot water tank. we got back from the casino this am, and i had waited long enough, i started to fill stove/system with water, I never thought that it would fill up, i think it took 1/2 hour, then i put some wood in the stove, and lit it, then turned on the blower/dampner, and holy cow we were building fire/water temp. once the water puked out of the vent i fired up the pump, by now the stove was running like a locomotive, i went inside to eat lunch, waiting for the furnace to stop sucking propane, getting inpatient, i shut off the propane to furnace, and waiting forever with my hands on the pipes in the basement, nothing happened, i went to the bathroom, and went back down stairs and holy cow, the pipes grew, and they were hot, and now i can keep my house at a decent temp, and not buy propane, i can't wait to see the propane guys face, when he comes over. any ways like they say i should of bought on years ago. i also do not regret installing a anti scalding valve, even though i its cheap insurance with little kids.
