DON’T get into HOT WATER
KICK STARTING the HOTBIN
The temperatures have dropped again and some of us may be expecting snow this weekend. Here is a quick reminder why you actually get a ‘(HDPE) plastic bottle’ with the HOTBIN with extras.
New customer, Phil, wanted to know if he could use two 2L bottle rather than the one 2L bottle we supplied to get a super fast start.
The answer is yes…but we forget to remind him that the ‘KICK START HEATER’ supplied is not just any old plastic bottle but made from High-density Polyethylene. Unfortunately you CANNOT use coke bottles (made form PET), plastic milk bottles (LDPE) or glass. PET will melt (see picture), glass can shatter when taken into the cold and or if you slip, and the very thin walls of milk container plastic will deform. There are not many H&S risks when using the HOTBIN – but taking care with using boiling water with the ‘Winter Heater’ is one of them.
Why is two good?
The basic idea is to add enough heat to get the central waste to 20-30C for a few hours.
Each litre of boiling water (at 100C) has 4200 Joules of heat energy. Double the Litres = double energy transfer = more heat in waste = more chance of bacteria getting warm and active.
If you are doing 2 – the secret is to get the lids on and then get each bottle into the bin super fast – leave the bottles standing for even a few minutes and half the heat will be gone.
See our WINTER post for more detail. Another top tip is to add the Hot Water Bottle twice in succession if you want a bigger boost.
