I have a project in hand which involves a 500W 230V. ac heater coil bathroom floor installation that does not do the job it was intended. ie It barely reaches 21C. Apart from lifting the tiled floor and starting again I am going to use a "Buck - Boost" transformer setup to increase the heating output by using a 285V ac input to the circuit instead of the normal 230V. mains. From my calculations ( with the heater coil at approximately 105 Ohm)this should up the present current reading from 2.1A to around 2.75A giving a wattage of roughly 770W.I would be interested if anyone else has done this and how far can one go ? The transformer I am going to use , when it arrives, is a 230V ac to 55V. ac.
