Sentinel X400

[Firegod]

Hey, our heating system is in need of a clean. It hasn't been done for many years and one of the towel rails was blocked with sludge yesterday. Never been off in 20 years! Took it apart and fixed it all. The water was black.

I'd like to run some X400 through the system and flush.

We have 13 radiators. Mostly double panels including 3 large towel rails. The dosage says 1 tin will do 8-10 rads in a typical system. Should I just get one or do you think a double dose would be safe?

I then plan to run it for a fortnight before flushing.

Thanks!

Smashing thanks. Gone ahead and ordered the 2 bottles of X400. I also as you say, plonked in x2 inhibitor and also the noise reducer as well into the order.

Cheers.

Hi, yes it helped in a fashion.

Ran it for 2 weeks and emptied it out, and it improved most rads. They are nice and hot to the touch. However, one rad still like warm. Took it off and flushed a load of crap out but still no dice. We ended up replacing the valves and that sorted it.

But the cleaner I feel definitely helped in a more general way.

I don't have microbore pipe but can imagine it can gunk up quite easily over the years.

Hopefully running the flush through will yield some improvement for you.
