Rated 4 out of 5 by Just Works Hard to say how well it works, but I've used it a few times, and never had any issues. Seems to work ok for a good price. I use two bottles on a med. 4 bed system. 23 Nov 2015
Rated 5 out of 5 by Named perfect Used this for the first time yesterday and is exactly what it says "No nonsense" highly recommended and cheap for what you get.. 16 Nov 2015
Rated 4 out of 5 by C.H. Inhibitor Better concentration than most competitors at a very good price. Time will tell if it does the job well. 12 Nov 2015
Rated 4 out of 5 by Typical NN product, good value Used this product at the same time as using a bottle of the No Nonsense leak sealer which definitely worked. It is hard to judge the performance of an inhibitor but given past experience with other No Nonsense products I have every faith in it. 6 Nov 2015

In an open vented system with feed and expansion tank 100L represents about 10 radiators.

In a sealed system 10 radiators would probably have a system volume of 70-80L because the feed and expansion tank has been eliminated.

On that basis a sealed system of capacity 100L would likely consist of 12 radiators.

It's always better to overdose than under dose.

And it's always best to err on the side of caution.

So for every 10 radiators (count doubles as two) add one bottle. For example in an 18 radiator system add two whole bottles.

Strictly speaking according to BS7593 it is not advisable to mix inhibitors from different brands - drain down, refill and start again with No Nonsense. All the variants (inhibitor, inhibitor concentrate and inhibited antifreeze) are compatible and can be mixed. If there is a small amount of a leading brand in the system we have not encountered any incompatibility issues. If in doubt please call our helpline on 0845 880 60 50 for a more detailed explanation.
