Pump Speed Setting

[Graham81]

Am I right in thinking that the pump in a Worcester Bosh 240RSF should be set to its max. setting as factory default?

Also I will be attempting to clean/descale the DHW soon, due to a problem perviously posted here. Can someone describe the inners. Is it just two loops of pipework running very close to each other, or do they loop backwards and forwards so that the surface area is greater to heat the water more effectlivey. Just wondering as I am trying to work out how to make sure the descaler gets to all the pipes inside.

Cheers in advance

Yes max.
Loopy pipe inside a mini "tank" of HW. Never cut one open but that's what I assume!

You might be able to buy a replacement failry reasonably - email me (see profile).
