Most of these Worcester (Bosch) boilers don't come with these sensors. The one installed by my landlord is so cheap it doesn't offer any regulation interface besides the one knob in the front. It also lacks any temperature display, so I had to tune it with external thermocouple.

Usually the boilers are also oversized for houses here. The temperature differential is not big enough and you waste quite a lot of energy through steam.

Finally, the system boilers are also the most common (as opposed to combi-boilers) and for that reason you are not supposed set them below 60 degrees.
