Central Heating Dosing Tool

Boutht it to add inhibitor to my heating system. Makes what could be a messy job easy to complete.

Spillage prevention and ease of access to radiator and fits properly

Easy to use, followed instructions which were easy. I drained 1.6 litres (measured) of water to apply 1 litre of treatment.First few fillings of the funnel went in quite quick but then slowed to almost nothing. I’m half way through the bottle and I’ve left it to leave this review. I’m not even sure the whole bottle will go in at this rate. It’s taking several minutes to lower a few mm them I’m going to be in a bind if the funnel doesn’t empty completely what do I do then?Any, easy to use works well but not fast and maybe not as good for 1 litre additive.

Just what I needed

A must for yearly inhibitor top up,Easy to use and no mess

As a gas engineer I use this to add inhibitor or cleaner to central heating systems, good quality tool.

Arrived on time. Very easy to use. Much easier than (partialy) draining by shutting off the header tank supply and running hoses from the boiler.

I recently used the Just Dose It Central Heating Dosing Tool for adding chemicals to my radiators, and while it does the job, there are a few things I think could be better. The funnel is easy to use, and it made adding the Fernox Inhibitor to my central heating system straightforward without any mess, which was a relief. The size of the funnel was also a good fit for my radiator valves, and I appreciated how simple it was to attach it and pour in the chemicals.However, the tool isn’t as durable as I expected. The plastic feels a bit flimsy, and I was concerned it might crack over time, especially with repeated use. It works well for the job, but I would have liked it to feel a bit sturdier.One thing I did like was the clear markings on the funnel, which made measuring out the correct amount of chemical easy. It definitely helped with accuracy, which is important when you’re dosing a heating system.Overall, it’s a decent tool for the price, but I think it could be more robust. It’s handy for adding chemicals without the mess, but I’d be cautious about how long it’ll last. 3/5 for me.
