Quick one... if you want to do a power flush from a combi boilers pump... whats the best way of tricking the boiler into thinking the pumps running (without wrecking the pump) in order to heat the water up in the system... as you all know, if you disconnect the pump the boiler wont wont fire..

its like driving your car for 200 000 miles without changing the oil and then fit new oil filter !

I powerflush everyday of the week, the best tip I can give is to buy a pump head adaptor from Fernox or Kamco, combis use a flow switch to detect the pump running, once this is activated this allows the pcb to let the fan start up before the burner fires. The flow switch usually will only allow flow in one direction and the trick here is to run the PF machine in the right direction to get the heat on and then switch the boiler off to get the flow going the other way once the you change the flow direction on the machine.

As with any chemical reaction its a case of the hotter you get it the faster the cleaning chemicals work, think washing the dishes in a kitchen sink, you wouldnt put fairy liquid in with cold water.

So you powerflush one pipe systems....didn't think that there was a suitable way of flushing those,other than pre-dosing the system a week before the flush and then seeing how the flush goes!! if you have any tips i'd be glad to hear them!
I wont flush systems with 8mm microbore on....i just dont think the 8mm pipe will allow the velocity of water through to powerflush it adequetley.....10mm on the other hand is ok.
And work is ok in birmingham at the min,but we are coming to the end of the powerflushing season....and i used to be a rocket scientist. lol.

Radial pipe isolation fog rad penetration , remember from base of rad up to 3 inches is critical even pre dosing . Do not bleed rads unless it's non mobile sludge upper panel cold ( only see this Aprox 8 times ) . With air in upper rad water is more turbulent .

ok so what you are saying is induce air into the top of the rads as to make sure the critical bottom 3" of the rads get flushed only? and i dont understand how you could isolate the radial pipe as this would surely stop the water from travelling around the system to the machine??? Am i correct in what i think you are saying?

Was at EGKB 7 years . You must of departed out of there at some point . Used to depart runway 29 3miles left turn for village noise then that prob put me over the top of your house . If it was a twin turbo prop I would fly over to iow up to Birmingham or on to diepp France ( best cakes in the world ) flew a friend over for his wedding cake , 40 min takeoff touchdown around town shopping we were back at Biggin 4 hrs and he saved £399 on his cake it was great too . Not that I like French , not that they like English let's keep it that way .
