The long awaited HOTBIN Mini has arrived and it features all the improvements we made to the HOTBIN 200 Litre

Leachate Drainage Cap
New Leachate Collection System

HOTBIN Mini features a much-requested leachate collection system. Leachate is naturally created as part of the HOTBIN composting process and can be used as a liquid fertiliser.

Like the HOTBIN 200 litre, HOTBIN Mini has a sloped internal base which funnels the liquid towards the drainage cap like water draining from a shower tray. This liquid can be drained via the cap as required.


New Lid sealSuperior Lid Seal

The new lid seal design includes a raised step around the edge of the seal that when closed inter-locks like a tongue and groove join. This much-improved lid seal helps to keep the lid firmly closed, prevents any water ingress during heavy rainfall and locks in heat even more effectively.



The HOTBIN Mini compost bin arrives assembled and ready to use.

It comes complete with:

  • Lid Thermometer to monitor temperature
  • Airtight lid and bio-filter to reduce smells and associated attraction of vermin and flies
  • Aeration valve plate to moderate temperature
  • 50mm thick insulating walls to retain the heat
  • Aeration base plate to disperse air within the bin
  • Removable front hatch to extract new compost
  • One black cam strap (to maintain an airtight hatch)
  • "How to" user guide
  • FREE Composting Support online
  • FREE telephone & email support

The EXTRAS you receive:

  • 25 litre bag of Bulking Agent
  • Extra thermometer to track the HOTBIN's internal temperature
  • 'Kick Start Heater' (to keep HOTBIN working in winter)
  • Raking stick

Excellent product
28 June 2021  | 

Ive been using the mini for over a year now after seeing it in action at the Malvern Show. It is extremely easy to use and now Ive ordered the new plinth the recovery of the leachate which I use on my plants diluted, will be easier to retrieve. I try and rehome my worms by removing and placing back in earth/pots as they are extremely good for the soil.

It does get hot
29 June 2020  | 

I was juggling with giving 3 or 4 stars as buying the bin I was only partially aware of it's composition and effectiveness. Firstly I personally think they are overpriced considering the downside to the design.

The MINI does not have the revised lid hinging like the MkII so can't be positioned back to a wall. The instruction manual says to lay it on its back and push the leachate unit into the recess. Not sure if this came separate in other models, but if you do this you could cause damage or I am reading it completely wrong?

My main criticism is the construction material. Although thermally good it could do with an inner and outer more robust skin. This would then allow a proper catch to the opening hatch on the front, as opposed by the after thought use of a strap which really only partially works. Because of its composition it is impossible to fix a proper catch.

The surface of both inner and outer are very soft and can puncture easily. The unit needs to be raised so that you can collect from the leachate outlet and you need to get something quite flat to empty out the compost onto. The current configuration is very messy as the picture on the manual shows.

It does get hot (120deg) and the worms don't like it but so far it is working well, having taken the front off (bulging under pressure) in only 4 weeks. I am sure it does what it says on the tin but I feel a little more should be done about the design and especially the hatch. Even if this had a fold down, hinged flap the strap would then only need to retain the upper part of the opening. It looks good and is neat.

I thank you for you very welcome feedback, we are always trying to make improvements where possible.

With regards tio the lid hinging we are a little confused by this one as the hinge mechanism on Mini and Mk.2 is identical.

Unfortunately some old user manuals slipped through the net suggesting that the leachate unit needed to be fitted, when in fact it had already been fitted in production. Your are right, previously this part was fitted by the end user, apolgies for any confusion this may have caused to you and other HOTBIN customers.

With regards to the durability of the HOTBIN we recommend taking due care when using items around the HOTBIN that could potentially puncture the bin. The material EPP (expanded polypropylene) the HOTBIN is made from is a robust material used in car bumpers and cycle helmets so although it is soft, it does bounce back and recover its shape.

An outer skin may help make the bin more robust however this would come with a significant increased to the RRP whilst not adding any improvement in the bins ability to lock in and maintain its temperature.

We are constantly looking at ways to improve the HOTBIN and we will take your comments into consideration, the hatch access/security is something we have been looking at but unfortunately modifications of this nature take time.

Thank you for you feedback
