Fernox 62436 Central Heating Protector F1 Express - 400ML

The only product I use for water treatment in a hydronic system.

I used this in a 13-year-old boiler and it corrected the pH in range. Easy.

my husband buys this every fall to get the heating unit ready for winter.

I would give 0 stars to this purchase if able--I have repeatedly contacted Amazon about this purchase looking to return the item--as seen in the photo this unit does not have the dosing nozzles required to transfer the product to the boiler--Amazon keeps referring me to Fernox and I have contacted them on the 9th--the 18th--and the 21st of October and have received only a form email--This product is useless without the needed parts and Amazon has done absolutely nothing to help

I haven't had a chance to use it yet! However, it is exactly what I wanted and it was delivered quickly!!

When I received this product . I got the can but. (No ) holes to inject it into the line. So I could not used it.
