Today is the first time that I put the central heating on in a long long time, but the boiler isn't putting any heat into the radiators. We have hot running water but no heating, there is also a small drip which looks like it's coming from inside the boiler itself, but as I am not a plumber I don't know what I'm looking for, also, when I checked it this morning the pressure gauge on the front was reading zero. Two of the pipes that come out of the bottom of the boiler are connected by a flex with a tap on each end, one end was open and the other was closed, I opened the tap which was closed which then made the pressure increase. I'm still stuck with no heating though, if anyone can help so that I can fix it myself then I would be very grateful. Ps: I don't know if it helps but the make of our boiler is Vaillant and it is only 2 - 3 years old. Many thanks 
Few checks ,,,, Is boiler set to operate rads? ie, winter setting .. Is thermostat.. room or on radiators set to allow heating ? Set stat high,, does burner light ? Is electricity OK .. Any warning lights on ? might be stuck diverter valve or pump . You did right to top up pressure though ,, Main thing is burner alight and no hot water in rads or burner not lighting , Different problems , t
