Central Heating Dosing Tool

I usually dose through the filter on the boiler but decided to finally give this a go and so glad that I did. As I have been told, (time and time again!), it is a lot easier. (No need to dwell on how many times I have been told-off, for fiddling with the filter) Just isolated one of the radiators and drained down enough for the fluid I was putting in. Opened both sides up top, (not sure if you have to do this but somebody mentioned having trouble with slow fill through the funnel, when trying to pour 1.6L of fluid. I only had 1L to do but rather than just open the bleed vent, decided to take out completely, for improved reduction of air resistance). Popped this in and poured, away. Fluid went down in seconds. So yeah. In my experience, this worked really well. Feels study and well made. Screwed in, easily and I experienced no leaks. Not the cheapest I have seen but far from the most expensive. Seems a bit costly for what it is and I could probably Macgyver something, for cheaper but who needs that hassle and with the quick delivery; it was a happy buy. Should get years of use out of it and it will certainly be my go to for any future dosing, from now on.

Very good. So much easier than trying to use a funnel and a cloth to bung the hole.

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.

Need to add fernox to a radiator? Just get one of these and be done with the faff, brilliant bit of kit

Brilliant product , well built and easy to use

It works well

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.

Great product, works exactly as expected, makes a messy and fiddly job a doddle to do.

Satisfaite
