Very Impressed
Monday, 19 January 2015  | 

I bought my HOTBIN in late August last year. It was well packed and looked sturdy, once unpacked. I was concerned that it might be easily damaged as it looks a bit like polystyrene, but there is no problem at all.

I half-filled the bin with some of the contents of my cold compost bin, some fresh lawn mowings, some soiled bedding from my chook house and food waste. Within two days the temperature was up to 40 degC and in the months since then it has varied between that and 65 degC, even on the coldest days.

I have broadly followed the advice given and added a few handfuls of bulking material with every caddy of kitchen waste. I have used shredded garden waste, shredded corrugated cardboard and some shredded office paper along with perennial weeds etc.. Nothing biodegradable gets thrown away now, and that fills me with joy!

The shredded corrugated cardboard has been a particular success. I put the board through my office shredder (seems to cope with it well) - then it gets used as chicken bedding (mixed with a bought woodchip-type bedding) - then it goes in the HOTBIN. The soiled bedding gets stored in a secure bin until I need it.

When one of my old chickens died before Christmas, the dear old girl was buried in the HOTBIN (I made a hollow, placed her in it, and then covered her with bulking material. I have put cooked chicken carcasses into the bin before but never one of my girls. Sounds macabre, but I didn't want her buried where she could be dug up by wildlife, and it seemed right to return her to the soil.

I emptied some compost (up to the top of the access hatch) at the beginning of January. I laid an old compost bag on the floor in front of the door, and put the door (upside down) on top of that as a receptacle for the compost (worked really well). The compost stirring tool was the best thing for hooking the compost out (unsuccessfully tried lots of other garden tools first!). No sign of any of the early chicken carcass bones - Impressive!

The compost above started to drop down, and I didn't want to be faced with a partially decomposed Mrs Mac, so I re-fastened the door before the big slump! The compost was mulch grade, perfect for putting onto the veg bed before I prepare them for veg later in the year.

Suggestion - It would be nice to have a means of tapping off the fluid produced from the bottom. There isn't that much of it, but it is currently being wasted, as it soaks into the ground below. My tomatoes would love it!

I am seriously considering getting a second bin, so that I can hot compost more of my garden waste, rather than wait so long for my cold compost. This website is great too - lots of questions answered and great support.

Worth Every Penny!
Saturday, 3 January 2015  | 

This was a big investment for us, we could have bought 4 or 5 traditional composters for the same price. But after reading the reviews, having the ability to compost meat and to be honest being able to have something this funky in the garden, I decided to give it a go and lie to my wife about the price. Anyway we have had it 6 weeks now and its amazing, the only real issue is that we don't have two.
We both love feeding it and checking the temp. So far we have managed to hit and maintain 60C using a grass cuttings, but we can maintain a healthy 50C without to much effort. Grass cuttings really ramp up the temp though, its great when you see the steam billow out when you open the top. If there is going to be a HOTBIN mark 2 coming out can you add the ability to use the liquid that flows out of the bottom, I am sure its a concentrated plant food and it seems a waste to let it drain away.
Anyway awesome product - worth every penny!

Just to say this is now day three of using the bin. To be honest before I used it I was very sceptical about its claims to get so hot.

Amazing! Just went out to look at the temperature on the lid this morning and couldn't believe what I was seeing. After a chilly night it was showing an incredible 40C.

I quickly lifted the lid to see what was going on and could barely see the contents through the steam! What an ingenious invention this hotbin is. Now thinking how can keep the supply of material going! (It was filled almost to the top)

Best cospost bin yet
Tuesday, 5 August 2014  | 

I have had my hotbin for 3 months now, and have delayed reviewing it until I have some experience. Without doubt it is the best compost bin I have ever had. It got up to 50 degrees in a couple of days and has been there or higher ever since, including being unfed for 2 weeks while on holiday. It swallows chicken manure (with shredded cardboard bedding), dog poo, all our kitchen waste, and some garden refuse. No flies, no rodents and not very much smell. I would heartily recommend it.

So, why not 5 stars? There are a couple of issues that could be improved to make it even better. Important to stress that theses are fairly minor things that have room for improvement not reasons not to buy one! The most important is leachate management. Initially it produced far too much of very stinky fluid, due to feeding it too many grass clippings, even though well mixed with shredded paper and bulking agent. the resulting pond led to it being banished from the patio to behind the garage. It no longer has indigestion, but still produces the coffee-cupful a day that still has to be drained away or my dog drinks it. Some sort of collecting spout would help channel it into a suitable receptacle.

Second is getting the compost out. You have to tuck a sheet of polythene under the door, get down on your hands and knees and rake it out with the stirrer tool. Bit undignified and a bit stinky if you have let any of it go anaerobic. A fairly minor niggle but something to think about for Mark 2.

Finally, it just isn't big enough. It copes very well with the compostable waste from 2 adults, 5 chickens and a dog, but there isn't much spare capacity for garden waste as well. OK I could get 2 or 3 more, but cost becomes a significant issue. If you ever design a mega-bin for large gardens please can I pilot test it!

PS I am not the John Adams from permaculture magazine who has reviewed it already - it's a common name!

Composter chuffing away nicely
Friday, 20 June 2014  | 

I bought the hotbin because I have loads of chicken waste to dispose of. My existing composters were not sufficient and took ages to produce anything at the bottom. Within a week of loading it up to the top I had 10 inches to spare to fill up again. I have a hotbin and a Green Johanna and the hotbin is constantly at 50-65 degrees. But you do have to stir it weekly and keep topping it up with fresh "food". The Green Johanna is supposed to be a hot composter but is barely warm. You can cook potatoes in the hotbin it is that good. If you could find a way of recovering all that heat you would be onto a winner. These are that good I am about to buy another so that tells you something.

Read the small print
Saturday, 14 June 2014  | 

I bought a Hotbin as I had nowhere to put regular bins. Like other very positive reviewers I've read here, my hotbin is chugging away nicely, 55 degrees. But I didn't realise what a faff it was going to be to provide ENOUGH shredded paper (husband's office sends theirs away, confidential); shredded cardboard (I spent 45 minutes -listening to In Our Time - while I cut up a large carton that had already been through a shredder); and buying sacks of woodchip for aeration. I was good at traditional composting, but with my new Hotbin I had to take out a very soggy mess, dry it, and remix it with the above ingredients; and yes, now it's working really well. I got more information (excellent) from the website than the leaflet. So it's not that free and easy to run, you need to invest time, care, and some money in it. Whatever you do, make sure you have accumulated enough proper materials and waste to get it started. Read the small print!

Unlike cold composting, HOTBIN is an aerobic composter where the bacteria require food to digest, oxygen and the right moisture content to hot compost effectively. This means that bulking agent needs to be added with waste to maintain good airflow (oxygen for the bacteria) through the bin and shredded paper should be added to help control excess moisture when adding wet waste in the bin such as food waste and grass.

Composting fun
Thursday, 29 May 2014  | 

Hotbin arrived well wrapped and was easy to lift by myself and place next to my wheelie bins. I followed the instructions to create a good base layer by chopping up garden material into small pieces and mixing with grass, wood chips and shredded paper so there was lots of air circulating. I filled the bin half full. This took some time and required patience but paid off as just a day later the temperature in the bin had risen considerably as indicated on the long stem thermometer.
Delighted with it and busy saving all kitchen waste and asking family to save it too so I can keep feeding the hotbin. Can't wait to dig out my first batch of compost as I know it will be of great benefit to my garden and veg plot and compost will have been created from things we would have previously discarded.
Having had a scare from a rat in my last compost heap I had thought that I would not be composting ever again. The hotbin has changed all that being pretty much rodent proof and I am delighted to be back making my own compost. Brilliant!

Just a few lines to sing the praises of the Hotbin. It was received on 13 Jan and brought into use on 16th. Today 23rd it is about 2/3 full and the temperature is 80 degrees. I would not have believed it and it appears to do exactly as advertised. I will describe the final result in due course.

I love it!
Thursday, 6 February 2014  | 

I have only had the bin for a week and already I love it. I have a very small courtyard garden and have had a compost heap for 18months with very little results.

It took more than 48hrs to build up heat but being a patient person I waited and kept consulting the leaflet. Its now running at 45 degrees and climbing.

One thing - I didnt read the leaflet properly with regard to the long thermometer and pushed it deep, then couldnt understand why it wasnt heating. up. Duh!

I am sure it will pay for itself easily and would recommend it to anyone.

Super Composter
Monday, 2 December 2013  | 

This composter is worth every penny! I only got mine a few weeks ago and didn't expect wonders as the temperature dropped and it was rather cold outside. I set it up with plenty of veg peel, cardboard and some plant cuttings and skipped adding the bulking agent as my dog has any food leftovers. I buried the hot water bottle inside and left it. 5 days later I came to add more feed to my composter and was pleasantly surprised when a load of steam came out after opening the lid...its working ! I am so impressed and happy; I wish I had gotten one much sooner. A very happy customer.
