Fernox Central Heating Protector F1 500ml
I had to drain the heating system and so needed to add an inhibitor when refilling. Fernox F1 has a good reputation and I've used it before, although not usually the cheapest option. Great to be able to get it at Screwfix on a Saturday afternoon, when all the plumbers merchants had closed for business.

We often go back to a system after years of 'benign neglect' to find everything working well and still a high inhibitor value reading.
Well worth the slightly extra costs - excellent value right across the range of products.

Have previously used the MB-1. Tried this and it seems ok, less space taken up in van due to being concentrated

Have used Fernox products in my central heating systems for the past 20 years and have always been happy with performance.
I like the smaller volume required with the F1 product.
