Maintenance

[trickyrad]

How often should a central heating system be cleaned? I'd put in the corrosion inhibitor into my system 4 - 5 years ago but when I looked in the header tank there was rust coloured jelly and a lot of slime. The next question I guess is how often does the corrosion inhibitor need to be topped up? What is a good maintenance regime? Yes you guessed it my system went bang last w/e.

jelly and slime would suggest you did not follow the instructions correctly.a correctly installed sys should not require cleaning just hot and cold flushing to clean it of installation debris.a poorly installed sys may require cleaning but you need to find the cause of the prob ie air ingress,poor circulation etc.inhibitor should be checked every year with the appliance service,most only require topping up every 5 years or so

the jelly and slime is bacterial growth, the correct procedure could well have been followed, but living things turn up later.

oilman fernox turns to jelly when it is poured in the f&e ,unless you drain some water first it sits in their without circulating forming a nice slimy surface turning to jelly just below the surface

In that case I'm glad I don't use Fernox.
