Maintenance

Today it was time to do the yearly scheduled maintenance to the central-heating boiler.
Here it is almost back together again but too late I realized that this was a subject for Blip. Otherwise a better picture should have been of the inside of the boiler furnace with burner and so on but I thought it too much work to dismantle it again just for the picture.
This boiler works for 14 years now and the only thing I had to repair in those years was a three way valve which switches several times a day..
So: not too bad!
I try to do the maintenance and repairs as much as possible myself.
But when the burner automation someday fails I have a problem...
