Potterton Netaheat 50 and 50 LPG

[adrianhyde]

Looking for a little assistance; my boiler isn't firing up and my heating engineer says that it is the Fan Pressure Switch that isn't working. He has tried his usual supplier today and they say it is no longer manufactured. Does anyone know if there is a suitable alternative? It is part number 64220403. I don't want to replace the boiler as I am having an extension built next year and as part of this am having a ground source heat system installed, so will not want a replacement boiler.

Any thoughts?

Try another engineer. There are probably several alternatives available, and you need to find a Gas Safe engineer who can think laterally.

Usually the pressure tubes though but I havent seen the boiler so you will have to go with your engineers diagnostics
