Hi there - we have a Grant Vortex wall hung oil boiler. It's been giving us some problems locking out all the time, and we've had a plumber visit and carry out various things, which have got it working for a bit... and then it lock out again. So far, they've changed the photocell, the control box and now the capacitor... so far it's working. However today, I noticed that when I was outside the usual smell from the boiler's flue smelt different - almost like a gas smell, rather than the usual smell we get when it's burning... can anyone shed any light on why the smell has changed - and if I should be concerned! (Just to add, there's no smells inside the house).
Thanks for your help!
