I hate being cold. But Florida does get cold north of Miami.
I love my propane furnace but keeping the propane topped up is problematic. When it's super cold, I do use the furnace to quickly heat up the RV then maintain it with the electric fireplace heater.
The fireplace is wonderful electric heat with terrific ambiance but it's not super quick. However it does maintain and feel great.
I also have two 200 watt portable mini heaters that are awesome. One I keep in the bathroom and the other I move around. Most often it can be found at my feet at my desk.
At night I run the 200 watt heater in the water closet all night long. If I have to make a 3am visit to the toilet, it's super nice that it is super warm.
To be very frugal, I enjoy cool air at night. I have a mattress warmer on my bed with ten settings. It is marvelous! I can sleep toasty warm while breathing in cool air and save a bundle on heating costs. When I get up, then I turn up the fireplace or furnace or both.
My little dog gets cold and he has his own bed warmer which he is very fond of too. Only problem is it turns off automatically and he hasn't learned how to turn it back on, so I have to check it all the time. Mainly I just turn it off and back on so the cycle restarts and he can enjoy it.
I also keep a blankie near the reclining sofa so we can both be cozy when watching a show or relaxing.
Life is goof. ;D
