Thank you. I think it is just more our prefrences. I'm more sensitive to sounds at night when sleeping and the furnace blower is a bit too noisy for me.
We have used an electric Delonghi digital oil filled radiator with an automatic thermostat for 8 years in both our home bedroom and in two trailers. Dead quiet, even heat and never a problem with this type of heater.
Our propane catalytic heater for dry camping is a Camco Wave 3. We have used it in our last trailer 2 years, quiet, even heat and never any problem.
A good thing is we both have an LP/carbon monoxide detector for our propane appliances.
Appreciate hearing how your furnace worked for you. Stay warm!
