I'm looking for suggestions:
We built a cabin two hours north of Anchorage, it is 20x28 with a full upstairs (gambrel barn roof style). We are on the edge of the grid and have electricity. We have running water inside with a kitchen faucet and shower, food, liquids, refirdg, etc..we have a Toyo and keep the place 50 degrees all winter by using the Toyo therostat. A monitor has failed twice and a power outage with the Toyo once caused us to replace broken pipes two or three times and clean up exploded sodas and other stuff.
I want to install an emergency heat source, probably propane. The top floor is isolated and doesn't need heat. We need a way to keep some kind of heat on if the Toyo fails due to failure or power outage. I'm thinking a propane heater with a large bottle that is indoor safe. A caretaker comes by every 4 or 5 days to check on things in trade for a shower. Do you know of a propane heater that has a thermostat and would automatically come on by itself if a certain low temp is reached? All that I find must be manually lit. We need something that will turn on automatically when we are not there and produce heat without electricity for 4 to 5 days in case the Toyo fails or electricity is out. We welcome any ideas. I can't find a propane heater that will come on by itself. Thanks.
