Hi Tony, A little point 50 watts is about 180 btu's. A British Thermal Unit is defined as the energy it takes to raise one pound of water one degree f. Assuming an upright piano weighs 400 lbs 180 btu's is *never* going to get the piano to 50 degrees C. (unless the room is 48 C already *grin*) Use the 50 watt rod with a humidistat. Things will be just fine. Regards, Don Rose, B.Mus., A.M.U.S., A.MUS., R.M.T., R.P.T. Tuner for the Saskatchewan Centre of the Arts mailto:drose@dlcwest.com http://donrose.xoasis.com/ 3004 Grant Rd.
