Heating Thermistor

Hi I’m new to this site
The problem I have is that I am trying to find out where I can get a thermistor from
I have an old electronic heating control system that used thermistors to sense the water and room temperature
I have attached a photo of the thermistor on the pcb
Can anyone help
Thanks Jim
