Effective but pricey
Repeat purchase so found it effective, although quite expensive and I have used cheaper products in the past with similar result. Would still purchase again but haven't been able to find recently.

Easy to use and good value
Product arrived on time and appears better value than many competitors. 500 ml treats up to 18 radiators, most competitors sell 1L bottles that only treat 10. Assuming it does what it says on the bottle, it’s excellent value. Very easy to add to the heating system.

This inhibitor works
This heating system inhibitor keeps the system in fine fettle and has the added benefit of removing lime scale from the boiler and prevents kettleing

Funciona muy bien para mantener la instalación
Este producto estaba agotado y me puse en contacto con el proveedor me dio respuesta rápida y me aviso cuando Amazon ya disponía de el. Contacte por email en ingles pero con frases simples y no hubo problema. El producto es muy aconsejable para que la caldera y la instalación se mantenga lo más limpia posible, además el ruido de la caldera a desaparecido. Resumiendo, no es barato el producto, pero si me ahorro de cambiar piezas de la caldera y un mejor rendimiento, sale a cuenta usarlo.

très bon rapport qualité-prix
Facile à mettre en oeuvre: après avoir retiré 1 litre du circuit d'eau chaude par un purgeur d'un radiateur au rez-de-chaussée, j'ai retiré le bouchon supérieur du radiateur le plus haut à l'étage pour vider le flacon. Puis remise en route de la chaudière avec remise en pression. Faire tourner quelques heures puis purger l'air comme d'habitude. Excellent résultat.
