Yes but I installed a Propane heater
I have one on my Catalina 30. It works sometimes.They are an electricity hog to boot. We have no shorepower so I just gave up on it. The Admiral was real chilly on those cool spring mornings.When volvo went out of production they gave all parts business to Espar. There are no Ardic parts that I could find.The company I work for is an Espar dealer. They have their problems and are electricity hogs too.I installed a Force 10 Bulkhead heater and have been really happy with it.It costs about $500 for the heater and vent pipe. Is really easy to install and keeps us toasty. I have a small 5 lb propane tank which lasted most of the season for cooking and heat.Go Oilers.
