Flomasta 0623 Concentrated Central Heating Inhibited Antifreeze 5Ltr is rated 5.0 out of 5 by 6.
Rated 5 out of 5 by from GOOD QUALITY ANTIFREEZE Did what it said on the bottle. Easy to add to the system and instructions very clear. Sufficient supply in the bottle to treat the whole system in one application. Would recommend to apply to all central heating systems.

Rated 5 out of 5 by from Flomasta c/heating anti-freeze I have used this product for several years in my French holiday home which is left empty for the winter months. Having suffered a burst several years ago, this is a precaution worth taking. Flomaster is much cheaper than French brands and certainly effective. It also inhibits corrosion. An excellent product.

Rated 5 out of 5 by from Best value We used to use the No Nonsense product and have now moved to this, they say compatible but frankly its just the same stuff with a different label and just as good. We use it in every install as we only do marine heating where antifreeze is a must unlike domestic systems. The drain down and renew periods can be extended by topping up with Flomasta inhibitor. I would take a lot of persuading to move to another product.

Rated 5 out of 5 by from Good quick delivery to France, Good quick delivery, only time will tell if the product is as good as claimed but heating system was instantly quieter and I believe the rads are hotter so, so far all good.
