Heat

we have hotbox's that steam 150 degrees - chewing gum has no chance

you can hire a hot pressure washer they can get to 120 degrees - you would need electric supply ( usually ) and that will do the job

Hello Darran

Are u using a generator to power ur hot boxes, as having an electrical supply is the reason I have not bothered picking one up.

Hi Matt -

my Hotbox's are diesel but you need 240 supply for the ignition for this I use a 2Kva Genny - if I had thought harder about it I would have got the version that runs off a 12v battery

I know the hire pressure washers will need mains supply and won't run off a genny - well not off mine that are 6.5 Kva

A hotbox requires very little power (it’s just a fan) a big enough transformer should run it from a machine or van 12v supply.

My mates runs his van pack burner from the van battery with a transformer.

Combination of pressure and heat is all you require to remove gum from block paving . 
Price accordingly as can be time consuming depending on soiled area

I'm running a hotbox off the machine battery via an inverter in one van and the H&M will also be run off an inverter and it's own battery.

Machine battery - crocodile clips & leads/tails to inverter (inverter changes 12v to 240 v) - hotbox (240 volt) plugged into inverter - inverter switched on - Boom hot water!!!

As has been said - you need very little power to run a hotbox.

i've got a hotbox but don't carry uit around with me generally. can anyone recommend a decent gum remover that will soften it so i can lift the odd spot off with cold pressure?
