Power flushing costs

A question I was going to ask you when you pop round to do mine but what sort of pressure is used by a powerflush? Is it a lot more than the pressure used by the central heating system? Is there a risk that it could it end up doing more damage than it solves or is it a relatively gentle process?

There is not that much more pressure, only ever had one rad go in the last ten years.

:jyes grimslave you are corect in your assumption,
old copper fittings that are not soldered properly or at all,:mad:
can come apart under extra pressure that a powerflushing machine with chemicals,
exerts on the system,
also the sludge ( black magnatite of iron oxide ) can end up
in the boiler waterways and parts.........full marks.......

well done top of the class.......:cool:

give that man a goldfish.........:beer:

powerflushing is completely unnecessary....:D

new systems should be cleaned and inhibitor added if a proper tradesman installed the heating,
in old systems most of the " black sludge " black magnatite of iron oxide "
has settled in the bottom of pipework and radiators.............and solidified....:o
therefore a general drain / cleaning of the system suffices,
your money is much better spent elsewhere.............take it from me.......

tatty bye :T

Did anybody, in the end, bother to answer the OP's question? Or is everyone too busy arguing amongst themselves as to who knows the most?!

what was the question again ..lol..
Powerflushing costs £245 for upto 10 rads in Leeds. Done one today.

The OP has left out vital info i.e. condition of system and location in the UK will dictate cost....so impossible to say from behind a keyboard (but this doesn't some from trying;)).

You have a point. Found one of these last week. Ancient endfeed coupling - must have been fifteen years old if it was a day - not a sign of any solder just a good welt of flux holding it together. Tank fed so low pressure and hadn't leaked since installation. "Came apart in me hand chief!"

Cheers

Not sure you are on about the same thing ? If it needed a powerflush then it would be central heating, most central heating systems need a pump.

He was on about unsoldered (it got forgotten probably) ancient pipework. I have given a practical example that this does occur having found one only last week. The fact that it wasn't on CH pipework isn't relevant.

What he might have meant (only he knows) is that what would happen if a joint such as this exisited on a CH system and which the ordinary circulator didn't cause to leak but that a powerflush machine might. I think.
