Are your radiators hot at the top cold at the bottom then you need the Trappex power hammer.

Derek in this video takes a look at trappex new power hammer for agitating radiators for removal of magnetite accumulations to reduce flushing times.

[@slyfox186]

Good video. I bought a Chinese one off ebay under a tenner, added system cleaner which puts the magnetite into suspension, isolated all rads and worked on one at a time (higher water pressure), cleaned magnaclean, drained, flushed, filled adding inhibitor, job done.

[@duckndive.]

Good idea, I just tapped my radiator with a small rubber mallet, it works!

[@mrgilly100]

I’ve got the magnaclean agitator. Stick a felt furniture pad on it and it’s works great without bashing up the rads.

[@rm-mastering]

Great video, as you've shown this agitator attachment is definitely worth the investment. As always thanks very much

[@Paul9]

I have one of those massage guns and I think would actually do the same job as this.

[@Benzknees]

Might try that, but using a much cheaper rubber mallet!

[@paul_my_plumbs_uk]

White rubber mallet will do the trick ✔️✔️✔️

[@amcluesent]

That's the wee wifey's Xmas pressie sorted!

[@johncanter9575]

I made one. Hockey puck from eBay and a 3/8 inch Drill Arbor Adapter from Amazon. Total cost was around £11.

[@namAlexander]

Jack Pad as that has a blind hole, drill and use a 10mm bolt and washers with a nylock nut at the back..£4.50

[@paul_my_plumbs_uk]

♣️♣️♣️ Vid del boy ✔️✔️✔️ i was getting agitated waiting for you to get on with it 😂😂😂😂

[@amcluesent]

Something to do when power-flushing. I'd be worried about blocking the heat exchanger doing that when the boiler was in the water circuit

[@stevenpatrick9213]

You powerflush without a inline magnet??? Maybe you should worry more about doing it properly with the right equipment

[@ElTelBaby]

@ 5:54 It's a shame U didn't have the Thermal Camera set up so that we could C just what is happening as it happens at the bottom of the radiator...

[@diegovd7215]

Hi Derek, thanks, interesting. I am definitely going to use my smartphone FLIR to check my radiators for large cold areas. I wonder if instead of using physical movement to put the magnetite into suspension in the liquid: could it be possible to do that with a couple of magnets? I should be able to model and 3D print a device containing 2 neodynium magnets from an old harddrive, set them with opposite N / S facing the radiator, and then adding an extension in order to mount it to a drill, that I could then turn slowly at the bottom of the radiator. I don't have a pound of magnetite and an acrylic model of a radiator to visually test the feasability of my idea, but it would be nice to have that. Coming back to the power hammer, I guess some Duct tape could be enough to help protect the device, instead of a cloth, maybe? Cheers, stay warm ;)

[@alanhodgson8443]

I use a magnet and a pice of pice of card and move along in the direction of the water flow it does the same Job for a lot less cash.

[@hugoscott7737]

I think the Trappex Power Hammer is a fantastic product which proves it agitates and removes metal particles .I suppose if you passed it over the radiator 3 or 4 times you would have got more out .Just bought one from BES ,great value compared to the Adey Vibraclean .

[@davebayliss3142]

Rubber mallet works just as good and easier

[@johntaylor6845]

Useful item and cheaper than a power flush, assuming you, sensibly, have a magnetic cleaner device fitted.

[@ununha]

Good demonstration 👍 Please try massage gun next time It might even cheaper

[@DominicParkinson]

Why would such a tiny amount of debris so radically affect flow in the radiator?

[@markchristohperowen6806]

it builds over time makes trvs stick as well as moving parts inside the boiler and heat exchangers. look at the radiator it has waterways that black stuff builds like a cake inside rads/pipework/boilers preventing heat transfer from the water you spent money on heating to the metal of the rad. even worse if its inside a heat exchanger. invalidates warranties on new boilers most have 10 years now. their engineer turns up and finds that cake inside a failed part........................its on you, and they will probably send you the bill for the privelege of getting one of their engineers out. inhibitor only slows down that process. and that degrades over time and needs to be replaced/topped up.

[@shawnferguson5121]

Rubber mallet kinda does the same thing !

[@MrRawMonkey]

As my flow temperature is set for 50C and the drop across each rad is around 12C due to the lockshields, all the bottoms of my rads are cool by design yet the implementation is this is wrong as “we need to make this radiator as warm as we can”

[@markchristohperowen6806]

haha. wait till you start thinking about poorly designed underfloor. and calibrated.

[@Thursdaym2]

Excellent videos from you but don't have such a drill and no need for one. So going to try mallet suggestions or even side of my fist.😅

[@akshayjugran4463]

Will this work with a normal drill? I have this on 2 radiators in my house and put cleaning solution in to see if it helps. Anything else you can suggest?

[@AndrewStrydomBRP]

This seems like something that could be useful for more than just radiators

[@markchristohperowen6806]

please dont .

[@AndrewStrydomBRP]

@@markchristohperowen6806 Haha I wasn't quite thinking that, it feels like something that could get air bubbles out of pipes and radiators too, along side being a cheap way to get a concrete vibrator when you have a metal framed wall.

Gone up from £28.95 to £34.74 in the space of 3 weeks. 20% price increase for a piece of rubber. Has there been some sort of price rise in the past 3 weeks that I'm not aware of or are BES just creaming off?

[@namAlexander]

you can make one using a jake puck with a bolt and nylock nut using nylon bushes and washers so the bolt spins in hammer mode on the drill

[@milkman100001]

so does that mean that inhibitor doesnt really work? all that magnate with inhibitor in the system!

[@stevenpatrick9213]

Have you even seen a new install system where they forget to put inhibitors in? Trust me inhibitors work very well

[@namAlexander]

@@stevenpatrick9213 yea mine i reminded them to put it in, take the smeg some people

[@namAlexander]

i take it you have the system on at full heat with the both valves fully open? as the heat is better on as its easier to loosen the sludge?

[@antoniogalluccio4213]

Did you do it with the system hot and running?

A pair of old socks would fit nicely over that rad hammer…….though I just use a conventional rubber mallet with an old kneeling mat to protect the rad from scuffs because who can afford to run a power drill these days anyway 😂

How can a rad be knackered? Apart from a hole in it....

[@tomkatgastraining]

When it’s full of sludge

[@00wei67]

It's not knackered. It just needs a simple flush & then it's good to go. If it's full of rust & had a hole in it Then it's knackered!

[@tomkatgastraining]

@@00wei67 a simple flush will not return the rad to its former glory if it has sludge in it then it has corrosion.

[@diegocamioneroeninglaterra223]

Simply buy raber hammer will do same job

[@ScottyDog345]

A rubber mallet should do the job shouldn't it

[@jimmyryan1988]

So at the start there was 10c difference between the top and bottom of the rad and the same at the end 🤣

[@David_11111]

perhaps you did not notice the colour change showing how the rad was able to dissipate heat over a larger area.... the water needs to flow so there will always be a flow and return difference !

[@jimmyryan1988]

@@David_11111 looks like they’ve changed boiler flow temp to give different colours on the thermal imager. You will always get some temperature difference across a rad if you didn’t then the boiler flow and return temps would be the same which they’re obviously not

[@tomkatgastraining]

I can assure you the temperature on the boiler wasn’t changed I guess more flow through and more surface area used on the rad won’t make it hotter then?

[@jimmyryan1988]

My point was there’s still a dt of 10c so for me nothing has really changed same flow rate through the rad imo. Trv has a tiny aperture maybe 6mm? I’d say this is likely a bigger restriction than the rad water ways

[@tomkatgastraining]

@@jimmyryan1988 the idea of the video was to show how much magnetite the tool could loosen in just 2 passes not how it could change the delta r of the rad
