Rated 5 out of 5 by from Great stuff! Been using this product for years. Does exactly what it's supposed to do.

Rated 5 out of 5 by from Good Value For Money It's a little difficult to rate performance on something like this but it does represent good value. It was easy enough to add to the system. I applied it with a small funnel through the top plug of the bathroom towel rail with no problems. I would suggest you have a rag handy though as there is bound to be a tiny bit of spillage at some point!

As No Nonsense Inhibitor is longer availabe, what similar product do you sell that is compatible as I have already added some No Nonsense Inhibitor to my CH system?

I understand that some types of CH Inhibitors should not be mixed together.
Asked by: KKJJ
Hello KKJJ, Unfortunately we could recommend an alternative scale inhibitor as it is advised not to mix brands within your central heating system. Thank you for using Q & A. DC

Can I add Antifreeze to a system containing this inhibitor.

My boat central heating system contains this, however as the boat is unoccupied and unheated for half the week I would like to add some Anti-Freeze, is this likely to be a problem ?
Asked by: Lonefox
It's no problem at all - you can add either No Nonsense Inhibited Antifreeze or flomasta Inhibited Antifreeze - they are fully compatible with the No Nonsense Inhibitor 500ml.

Can this be used to top up a system that has another brand of inhibitor already in

Therefore we advise that you contact a local tradesperson who will be able to view and assess your particular requirements. They will be able to provide further advice for the installation/usage of the inhibiter. Thank you for using Q&A.

can this be used at the same time as leak sealer

weve a small leak somewhere in the system that makes the boiler pressure drop, so were going to drain down & use the no nonsense leak sealer, so could we use the inhibitor at the same time?

Can this be used on underfloor heating and how many litres of system volume will 500ml treat ? Thanks

Asked by: Boilers
Yes it can be used with underfloor at 500ml per 100L. Alternatively you may choose No Nonsense Inhibited Antifreeze to give frost protection in addition to corrosion and scale protection. The later product is added at 25L per 100L.
