I just found a wall mounted bathroom heater at Home Depot that is regularly $48.00 on sale for $19.00. It includes a towel bar for heating towels. I purchased two of these and will mount one in the livingroom and one in the bedroom. I removed the towel bars as I did not want them. I especially liked the mounting bar that allows you to remove the haeater to clean it.
They are a Kenwood Wall-mounted Bathroom Heater with towel warming bar. Model# HWB50TK
They are very quiet and will replace a ceramic heater that failed earlier this season and an oil filled radiator. The heater has a thermostat, timer, 750 Watt or 1500 setting and an anti-freeze setting that will come on at 41 degrees. I will use the anti-freeze setting as I drain my lines in the winter but do not use the pink anti-freeze, as we use the coach periodically throughout the winter.
