Cleaning Habitation Gas Lines ?

[RAW]

So my understanding is that Gas LPG and bottled Gases can be unclean fuels, they contain substances which can leave deposits on pipework and burners.
As Sylvia is pretty old I am wondering if the Copper Pipes to appliances may be clogged up, thereby reducing Gas Flow. Notably why the heater is working poorly.
If that is the case then how best to clean them ?

I fitted an inline filter on my tank. It seemed expensive but it might prevent this.

Gasit do the inline dirt trap filters
