Question about Heating & Cooling
Hi there my boiler seems to run okay with just the hot water on but when I put the heating on it runs for a maximum of 15 minutes then the burner and pilot light completely shut off, I've recently had an annual check and its been doing it since then but I've never had a problem with it before. any help would be appreciated thanks
Go back to whomever did the annual check-up, and get them to explain what they did, as you are not satisfied with the service. IF there was an adjustment done, they should have told you what was observed and done. IS this gas fired, propane, Fuel Oil ? depending on the fuel, it can be a variety of things that go wrong to give the symptoms you have described. I would start with the 'inspection' part and go from there.

that sensor as you call it is a thermacouple it produces a small current which lets the gas valve know it is ok to open . if the pilot is not clean and correct it will not let main valve open. if your pilot is good then you have bad gas valve. you may have low gas pressure this can also do what you are describing

Sounds like the flame sensor is dirty or bad. This sits in the burner flame when the burners are running. This usually has a single white wire connected to the back of it.

If this an older style boiler remove thermostatwires
at boiler terminal board and put jumper between R and W, if boiler starts you have bad thermostat.
If it does not come on then it appers that you have
a problem with the spark ignition or glow coil is
