Anyone used these? I tried the Wickes own brand leak sealer which had no affect. Used Fernox F4 which was £20 but worked perfectly

If your fixing a leak which overtime could have serious damp issues.....why would you put all your faith in a £2.79 sealer ;)

Similar Fernox storey - Used the no-nonsense inhibitor and we were forever bleeding the radiators. Used the Fernox stuff (far more expensive) and it was vastly better. You pay your money.............
#7
You'd only use this if you had a leak right? Or can it be used as a preemptive measure?
#8
Also, the heating Cleaner and Inhibitor are on sale - should I buy and save for later? My radiators are only a year old atm and have no problems or is this a service that should take place every year?

Are you implying they should yearly? How many 500ml bottles will I need for 5 radiators?
#11
I thought central heating system is a closed system, how do you get these into the it?
#12
I have just moved into an old house with an old CH system and I don't have a clue how its been maintained. Would it be worth using any / all of these or is there potential that it could cause problems...?

The same way as you get water into it (_;)

I'm no expert but I think I read somewhere that if you have one of these fancy towel warmer radiator things, you can isolate it (turn the inlet and outlet off), syphon a bit of water out of it through the screw plugged holes on the top (sorry, you can sense my technical knowledge here LMFAO) and then tip this in before closing it back up and openning the inlet/outlet valves back up.....

EDIT:

Looking at giving mine a clean in the summer, how do i locate venting points, I've got no idea what they'd look like?

should be on a bottom rad .youll need a hose & jubilee clip. turn off the heating and water inlet and any open up the drain off valve shove the hose on the end tighten the jubilee clip on so it doesnt shoot off! open the rad bleed valves top to bottom. thats the system drained . you can then take rads off & flush with a hose pipe or i open the ch feed tank valve & let the water run through ( close bleed valves , then reopen). This has always worked for me . I just put the inhibitor in the ch feed tank then ( when the system is approx half full ) doddle ! rads run nice & hot and boiler more efficient . this all depends on your boiler set up mines very simple some have filling loops etc.
#17
I just done my radiators last week, filling is actually a bit of a pain if you don't buy a filler device/pump as although you feed liquid into the top nut in the radiator, the hole is slightly higher up (at least in double walled radiators) - what I ended up doing was using a 15mm elbow joint and a squeezy water bottle with the fluid in it and squeezing it in which worked fine (assuming you have an elbow joint) - was a lot of spilling/swearing before getting to that point though.
#18
Out of stock for me! :(
#19
OOS everywhere near me too
#20
you can buy the kit with the adaptor. if you have a newer radiator you let some out. or drain the boiler down. then undo the bleed valve. take the whole thing off. the adaptor then screws on and you fill up

best way to clean radiators is to take them off and flush them. always have inhibitor in there too. a magnaclean is decent to have

way to tell is feel the bottom of your radiators if they never get hot but the tops boiling there will be loads of sludge

For those that have a sealed system and small radiator bleed valves, the following inhibitor will deal with the problem and it has been reduced from £9.99 to £3.19

After using it, save the cartridge and the nozzle. The cartridge can be refilled with inhibitor, cleaner or sealer. This can be done by removing the plunger with a hook, refilling the cartridge then refitting the plunger.;)
#23
If you use filling kit with a hand pump, like the Kilrock filling kit. They tend to work very well to pump out water but can be messy when pumping fluid in - best just use a funnel.

Exactly way I understand it if theres inhibitor in there and you dont touch the central heating system its fine as no oxygen in there to create rust so hardly any corrosion.
