I used screw in automotive-temp sending thermistors in hot water panel. Sealed, take pressure, and don't have to worry about electrolysis. You can calibrate their resistance with vegetable oil on the stove with a good thermometer.
Ask auto parts store (during low traffic time) to look at a few of their assortment of senders. SAE threads may be difficult to find these days.
