That's the best I can do from my phone. I can't use the picture link for some reason. Yes I don't have a thermostat but I haven't had one for 6 months and she's never had this. I've disconnected the heat as you say until I get one.
The things that gets me is the entire tip of the tail is brownish where the rest of that area is fine. Too small to get a pic.... I wouldnt be able to get her to a vet before wednesday. I guess I'll see if it progresses without heat and keep giving her betadine baths?

Unfortunately that does look like a burn from the photos. If you haven't had a thermostat on that uth for 6 mos then this is the end result . We are all glad you caught it before it got any worse! Alternate the betadine soaks with chlorhexidine gluconate for the antiseptic properties but the main medication if this truly is a thermal burn is silver sulfadiazine and that is only by prescription. Another medication would be the antibiotics the vet would prescribe as well. You should really try and get it evaluated by a vet asap. Remember to consider a alternate way to keep your bp within the required temp and humidity zones. Good luck and stay in peace and not pieces.
