Answers: Its much better for your home to use the central heat system that was designed for it. There is something wrong I presume for the power consumption to climb so high. How long have it been since it as serviced, A centralized unit desires To be serviced at least once a year and the filter need to be changed once a month. Have your element serviced. A portable heater is for a unheated room to be precise rarely used, or for culture who don't have interior heating
Hope this help
