Power flushing boilers

[tommy1712]

Evening lads I am relatively new to power flushing.
what are people's views of flushing boilers? I have only flushed boilers with cast heat exchangers through fear of damage.
i always get a disclaimer signed (off the kamco website)
if I am unsure of its a combi I just attach it in the f&r totally taking the boiler out the picture

I always flush through the boiler (but i do use a magnacleanse with the flusher) either use a pump head adapter or cut into the return under the boiler.

I always go through boiler if combi or through pump head if not. Hot power flush means you can feel the heat picture in the rad to make sure it has been cleaned out. Rubber mallet helps with a bit of agitation to get the sludge out of the bottom of the rad if needs be. I use sentinel x800 and then no risk of damaging anything, corrosion inhibitor when I'm done.

Also meant to say I use the Kamco CF90 and their magnet too

I have only flushed one with the boiler on and it kept locking out ever time I switched direction so thought best to just turn the boiler off lol.
I was thinking about fabricating my own heater bit of waste pipe, a immersion, couple end caps and a couple tank connectors
I do really want a magnacleanse but I am struggling to justify

I've got a magnacleanse, it's a great tool to show the customer what you are doing and achieving results. [emoji3]

How many of you own power flush kits ?

I go through the pump head especially on combis otherwise you can't flush the plate heat ex in situ...

Kamco do a unit a lot like a magnacleanse, with two chambers. They supply it with two magnets but you could put an immersion into one chamber if the boiler won't fire...

In fact, they now sell a combined twin-chamber unit with one magnet and one immersion. Should have patented that idea!

I've got a Kamco machine and magnets. Great bit of kit..

 

[tommy1712]

Yeah I have seen that and it does look good but really can't justify it

Expensive and worth the cost?

 

[macackau]

Expensive and worth the cost?

I think so. Works really well and the magnet collects all the sludge.

I'd definitely say Kamco is worth the cost.

Im unsure on the immersion heater though. Has that really got the power to heat up a heating system?

I have the twin immersion and magnet set up. Immersion will get you a rad tepid/Luke warm so you can feel for heat picture. Won't heat it up by a great deal but enough to help you check a rad has been properly flushed.

 

[Masood]

Expensive and worth the cost?

Yes definitely, paid for itself. I charge £400 for up to 7 rads then £50 per rad. Paid for itself very quickly.

It won't heat your house, but it heats up enough to get the chemicals working much much more efficiently and thoroughly. Even on a 3-4 bedroom house, a 3KW immersion is anough to get all the rads lukewarm. Which helps to check how well the flush has worked, as well as helping the chemical reaction.

I want the kamco mag and heat unit but it's just a crazy price, I can't charge extra for the flush and I allow a day to do a flush ok I might finish a a hour or 2 faster but it won't generate and more £££ and it ain't my water bill lol.
Unless anyone can tell me how it will do a better job

I build the price and time for the flush into every boiler quote.

My norstrom has the heater built in. It heats 50L of water to 60 degrees. Then as you do radiators individually it works that way. Wont do a full house. Heater is 3kw
