Rated 5 out of 5 by from Best of Breed A must additive when commissioning a new system or making changes/additions to an existing installation - lives up to it's reputation - could benefit from a 'fill tube' cap to make it easy to insert into radiators through the blank-stop hole without the need to mess around with a home-made funnel !

How many bottles will I need to put in after draining down my complete system?

It's a open vent system in a 3 bed semi with 12 radiators
Asked by: 4prop
Hello 4Prop. As you have a 12 radiator system we would recommend using 2 bottles of F1 500ml to fully dose the system. Hope this helps.

Where is shown the expiry date on the product?

Asked by: Cosmin
Hello Cosmin. The Protector F1 does not have an expiry date, but does have a manufacture date printed in MM/YY format on the front of the bottle, just above the label. The F1 Protector has a shelf like of 5 years, so you can check if the product is still in date by checking this. Hope this helps.
