No moving parts

I had to stay in most of the day awaiting the arrival of a heating engineer to take a look at my water and central heating boiler.

It is very stationary, not only because there are no visible moving parts, but also because it is on strike. No heating and no hot water. Well it is quite old, and when new it was one of the first of its type.

Hopefully when the engineer comes back again tomorrow and looks at it again it will feel admired and come back to life.
