"Emergency heat" from oil-filled space heaters - advice please

[newbury]

Site is northern Mississippi, main concern, other than $$$, is to prevent pipes from freezing.
Motor on heat pump/furnace (~15+ yrs old, 6 ton unit) went out, our son who knows about this stuff (responsible for data center environment, heating and cooling) guesstimates $300 to $500 to replace minimum (motor etc.) will be looking into replacing whole kit and kaboodle partially because it was a cheap unit installed before we bought the house.
Place is unoccupied for a few months, we are stuck in northern Va for months for wifes eyes (surgery etc.). Main concern right now is to prevent freezing if the temps get down like they did for a period in 2021 with about 2 weeks of cold (for the area) weather.
So my first thought was heat tapes around sensitive areas. Son suggested a several oil filled radiator heaters and wait out the winter while he researches quality replacement units. My BIL could wheel them in. Electricity is only ~10 cents/Kwh. They could come in useful in later years in a couple of upstairs rooms.
So without further adieu - any recommendations for such Portable Electric Radiator Heater, Oil Filled in the 1500 watt size? A QUICK search found Kismile Portable Electric Radiator Heater, at $80@

Can you drain the pipes and use RV antifreeze in the toilet and traps?

We have done this over 50 years in snow country.

If it is unoccupied why not just turn the water off and drain anything holding it? No way I'd chance space heaters without a person with them.

I have one of these Dragons for the wifes bathroom. It can safely be between her toilet and cabinet because of the design. It really throws the heat out the top but with no fan.

Just winterize the lines. It would be easier and cheaper than dealing with heaters.

The oil filled radiator space heaters are pretty decent.

We have one in a small green house enclosure to keep some plants from freezing over the winter.

The one we have is a set and forget type. Set the temperature to the desired temperature and it has a built in thermostat.

The only issue is if there is a power outage then it defaults to off and a 95° temperature.

We have another that has a dial for temperature and then a low, medium, and high setting for output.

If you have someone that regularly checks the place, then the higher end model with the digital temp setting will work great, and save t out some money since it only runs when needed.

If you don't have someone to periodically check on the place, then the dial ones will probably work better since once they are turned on, they stay on.

Much as I like oil filled heaters for their gentle warmth, we have had one leak.

I would not use a heater unattended. Like @ultrarunner suggested, I would drain the house lines, blow them out with compressed air if you need to (there are nice garden hose to compressed air adapters), and pour some RV antifreeze in the sinks, toilets (and dishwasher, and washing machine, depending on the model), and you are done.

Much safer. If a pipe cracks, you can deal with it when you are there, rather than trying to rebuild.

Free advice...

All the best,

Peter

Like others have said... winterize the house. Much safer and a lot cheaper. You won't need to worry constanly if the heaters are working.

Electricity could go out and the pipes could freeze anyway unless you blow them out and use RV antifreeze in the traps as others suggested.

Can you share brand/model?
