The updated 200 litre capacity HOTBIN Mk2 - like most things that work - is a simple design to help maximise what nature does by bringing together the right conditions to make hot composting easier. It is the bacteria decomposing the waste that generates the heat and the HOTBIN aims to keep them happy so you can enjoy fast successful composting.
Winner of 'Best Compost Making Product' in the 'Great British Growing Awards 2018'
The 55cm wide by 55cm deep and 115cm high HOTBIN composter does this by providing effective aeration between the bottom air inlet plate and the air outlet rotating valve, removing excess water through the valve as steam and allowing you to control the rate of heat loss.The HOTBIN can achieve hot composting between 40-60 °C, which means it can produce a rich compost faster. These hotter temperatures produced by the HOTBIN means you can recycle more types of household waste, even food waste.
The HOTBIN works all year round including the winter months, it arrives assembled and is ready to use and comes with a whole entourage of extras which will help revolutionise your home composting set up!
HOTBIN Mk2 Redesign - What's New?
- Leachate Collection System - the redesign features a much requested 'Leachate Collection System' which collects the naturally occuring leachate which can be used as a liquid fertiliser. The newly designed angled base funnels the liquid to collect in the base which can then be drained via the tap when required.
- Superior Lid Seal - redesigned to include a raised step around the top edge of the HOTBIN seal which interlocks like a tongue and groove join when the lid is closed. This improved seal helps keep the lid firmly closed, prevents any water ingress during heavy rainfall and locks in that heat so the HOTBIN works even more efficiently.
- Even Better Looking - The protruding hinge has been removed from the original design to make the whole unit perfectly square. The aeration mesh now slots into the base instead of sitting proud on the exterior of the unit, improving the overall look.
- Collecting the nutrient-rich liquid fertiliser from the HOTBIN is now even easier with the new Optional HOTBIN Plinth (GCO-043). The Plinth raises your HOTBIN off the ground by 125mm (5 inches) providing easy access to slide a suitable receptacle underneath the HOTBIN tap when draining the liquid fertiliser.
- Durable, sleek and hardwearing, situate the Plinth on a flat level surface and ease the HOTBIN into the contoured raised edges to provide a snug, firmly nested fit.
- Makes collecting liquid fertiliser easy, Quick and easy set up and install, Waterproof and all year round weatherproof

I have my my HotBin composter for so many years now that it has survived a couple of major moves, be aware it is fragile when empty if you twist it from the top. it is worth reading the instructions for use and keep mixing brown and green materials, as many others do I shred twiggy/woody materials in garden to mix with vegetable waste grass cutting dead flowers etc, and I do use the aerator device or carefully use garden fork occasionally also brilliant for shredded post bank statements or old secure documents, once in composter they control the moisture levels and provide more carbon to the mix the compost produced goes into a holding bin which is used for cuttings, seedlings and mulching i have finally done some damage to the body by attempting to relocate a few feet without emptying first (act in haste repent at leisure!) but it still works. amazing number of worms have moved in. expensive yes worth it definitely
purchased the wrong time of year to give a full review , I have used the bin for 2 weeks , At the moment the temp gauge reads a steady 60 deg F so not bad from cold and half empty . Bin looks well insulated and sturdy so should last.
I have had one of these bins for almost three years and found that it takes a reasonable amount of attention to work well. The turnaround for compost is much faster than a small compost heap but the mix of green and brown materials must be right otherwise it will not heat up to the higher temperature required, worth adding fine wood chip to the mix. The bottom lid wears after awhile and does not fit so easily and the straps become frayed also watch the air holes in the base are kept clear. Better than a compost heap, keeps the rats out and is tidy but not a complete success.
The HOTBIN Composter comes with a whole host of accessories to help your hot composting take off;
• 40 litre bag of bulking agent (composted wood chip) to use if recycling food waste included in the price
• Long-stem thermometer for tracking temperature during setup of the HOTBIN included in the price
• Raking stick included in the price
• Winter 'kick start' heater (also known as a 'hot water bottle') included in the price
The HOTBIN comes in one size. To keep it hot composting, you need to feed it a minimum amount of waste regularly. It is important you match the HOTBIN to the amount of waste you generate. The unit is designed for a 3-5 person family with a small-medium garden.
In the unlikely event you experience any problems with your HOTBIN composter, you can contact the HOTBIN Helpline on 0845 621 0095, drop an e-mail to firstname.lastname@example.org or visit the HOTBIN website at www.hotbincomposting.com
You can also download the useful HOTBIN USER GUIDE (1.09MB) with advice on how to set up and maintain HOTBIN.
The amount of liquid you will get will vary from user to user depending on the types of waste that are added to the HOTBIN. If you are adding predominately kitchen waste/grass which is high in water content you will produce more liquid, so make sure you are balancing out your paper. Please have a look at the following link: fix excess water issues
As long as you are hot composting the main thing is to keep your nose alert to a change in odour, as this will tell you if the bin is too wet and action needs to be taken.
Be aware things can change dramatically when high water content food waste is added. Each 5 litres (small caddy) of food waste will have 3-4kgs of waste which can contain up to 2 litres of water (i.e. a full large mixing jug).
Water is released during the composting process. In the HOTBIN, much of this water is removed as steam through the valve in the lid. However, when there is excess water it will drain down towards the ground, as it does, it dissolves humic compounds from the compost to form a dark brown liquid
It’s natural to get an overflow of liquid for different reasons as long as the liquid produced from the HOTBIN does not smell it is a good sign that everything is okay. The main thing is to keep your nose alert to a change in odour, as this will tell you if the bin is too wet and action needs to be taken.
If you are putting a lot of ingredients with high water content like grass and veg peelings you will make more liquid so, make sure you are balancing out your paper. When adding grass add 50/50 paper. Please have a look at the following link: fix excess water issues
Basic guidelines for collection & use of Leachate
- Always dilute liquid fertiliser (leachate) at a ratio of 1:10 (1 part liquid fertiliser (leachate) to 10 parts water)
- Once collected ensure the liquid fertiliser (leachate) is used within a 2-week period
- Do not use the liquid fertiliser (leachate) if there is a putrid smell or if you are draining it from an anaerobic HOTBIN.
- When draining we always recommend wearing gloves.
The liquid created by the HOTBIN does not have a high NKP (Nitogen, Potassium, Phosphorus) value so can be used as a fertiliser. The brown odourless liquid will be mainly Fulvic Acid and Humic Acid - both improve the uptake of minerals and can stimulate plant growth. Ensure you have collected an odourless, dark brown liquid. Take care if you have collected a fruity / acidic yellowish liquid, or a black pungent drain like thick slimy goo – see ‘why does the liquid fertiliser smell’ below.
Why does my liquid fertiliser smell? What do I do if it smells?
If the liquid produced by the HOTBIN smells fruity, acidic, or is pale yellow rather than dark brown these are good indicators you have excess water in your HOTBIN and the water is leaching intermediary organic acids out as it drains to the base. To stop the contents from turning anaerobic, you can remedy this by adding in extra shredded paper/cardboard to absorb the moisture and extra woodchip to provide additional aeration in the HOTBIN.
We do not advise you apply such liquid to plants. Many of these acids can be phytotoxic (bad for plants).
If you have black liquid or liquid that has a putrid or pungent drain like odour – the contents of your HOTBIN has gone anaerobic. We do not advise using this liquid either and you will need to correct the anaerobic contents, you can see how to fix an anaerobic HOTBIN here.
The liquid does look like good stuff so as long as the liquid produced from the HOTBIN does not smell it is a good sign that everything is okay. Keep your nose alert to a change in odour, as this will tell you if the bin is too wet and action needs to be taken.
