How much inhibitor do I need for my CH System?

[kk3960]

Can anyone help in advising roughly how much central heating inhibitor I need, I've just finished my heating install which consists of a Worcester 42cdi and 12 rads in a 4 double bed extended semi detached house. The system is generally plumbed in 15mm JG speedfit, and 6 of the rads are K2 double panel.

Thanks

Suggest that you read the Manufacturers Installation instructions that came with your appliance. Its all in there.

Dreadnought.

Or, better yet, ring the the tech guys, and ask them, do not forget to mention to them the use of speed fit.

I use Sentinel.

X100 is dosed at 1%, so a litre bottle will do a 100 litre system.

Mine is just under 100 litres, including the boiler, cylinder coil, nine radiators over three floors, and a feed and expansion tank. Most houses would be less, especially if sealed system with no F&E.

If your home is bigger just get two bottles.
