Your best option is to replace this old technology with a heat pump, which is much more efficient. Since your house already has ducts installed, it may be the right candidate for a central heat pump system.
Newton has partnered with a State program called Heat Smart, which helps residents to evaluate different options for heat pumps and to find contractors. These services are free. Please contact Heat Smart at http://wepowr.com/HeatSmartNewton
