Power flush advice

[yokomoano]

Hello. Aftter more problems with our baxi 105e we have been told by the latest engineer we need to have our pipes power flushed. Firstly, is it best to get a pro for this? Secondly if so, please could someone leave a rough est price fot the North East area England. I know this may be open varation.

Cheers dears

another question whilst we're on the topic:-
Is it easy to flushout the DHW circuit of a combi boiler, using a powerflush machine hired from HSS or whoever ? i.e. going in through the cold water supply and out of the DHW ? would I do this with the boiler on but the thermostat turned to cold ?
My hot water isn't as hot as it was, and i'm in quite a hard water area, so think that the secondary heat exchanger is a little fouled up
