How do you guys clean systems in the summer

[dolph]

A lot of you guys helped me out a few weeks ago.

As always thank you; I followed your advice and have fitted the new AAV and leak cured. Think, as you said, there was crud in the system as the water that came out was a pretty poor colour.

I had thought to put in some more Fernox Protector but really I think I should clean the system whilst I have the chance.

Now I understand how to put in the cleaner and leave it in for a couple of weeks, drain down and then refill putting in my Fernox Protector.

However for the cleanser to work in that two weeks the Heating I presume has to be on, and it is now the summer and the last thing we need is for the central heating to be working.

How do you guys get round this or do I have to wait until October/November?

I do remember when the new boiler was fitted the guy ran the system for a couple of hours with the water running straight through until it became clean, he had put some cleaner in, I think, before he started but only on the same day, again Fernox as he left the container in the loft (put in vented plastic tank, before he converted to unvented). Did he run the pump as the water seemed to me to be warmish.

As usual any assistance greatly appreciated

A Powerflush would be a better way of cleaning the system thoroughly in one day

Plus take all the rads off and flush individually (with a hose pipe in the garden). Best done with the BBQ on and the San Miguel a'flowin.

Either that or buy a rubber mallett. No fun in that IMHO.

Is it a combi?

sorry should have said Vokera 35e Mynute, not combi, sealed unvented system. Fitted about 5 years ago, the water is not that bad but it is darker than I would like and has a few bits in it. The actual heating is fine, no problems, just thought whilst I was "messing" about could get the system even better!

Was looking for a simple clean out but if I have to leave a cleaner in for a few weeks and then drain down thats what I will do, but will have to wait, unless someone can suggest a "summer" solution

Stick a cleaner in that can stay a long time, like Kamco Hyperflush. Make sure all the radiator valves are shut when you put it in, that way you get a nice strong solution that will clean the boiler and cylinder twice a day to start.
