Hi everyone sorry I haven't posted in a while but sure you know what my memory is like.
As some of may know I haven't been feeling great for some time now and have missed bookings and not replied to some messages. I was admitted to hospital on Tuesday morning with breathing difficulties and chest pain, after many tests it appears I have bloodclots in both of my lungs causing my heart a little trouble.
I won't be available for work for at least two weeks after am released from hospital and potentially 6 to 8 weeks before I'd be able to do anything heavy work related. So sorry if I've not replied to you or haven't got to you yet and if you need something urgent you will have to go to someone else.
Regards Darren.

The humble nozzle on you oil burner, more to it than meets the eye, a total of 5 parts and a very small hole in the silver disc which is where oil is sprayed in to the combustion chamber at high pressure. You should ensure your oil is clean, free from water and filtered correctly.
