Having used a single Southern Burner to heat an 8x12 greenhouse for many years, we find it can't quite keep up with the heating demand in our new 12x16 greenhouse. We'd like to add another heater that does not require a chimney pipe. Rinnai makes a couple of direct vented models that are probably more efficient than a Southern Burner, but with the added complexity of fans and considerable electronics. We wonder if the humid atmosphere would damage such a sophisticated heater. Please share your experience using a Rinnai or similar direct vented heater in a greenhouse. Fred in Lakewood, Colorado
