Which hot box do you guys feel is the best on the market in a price range from £1k- £2k ? Or is there one hotbox out there that can produce 150C but obviously not in that price range . Ed  
What do you want it for?
 Hot boxes will only do 80+c@ 15lpm not much more.....regardless of what the generic thermostat is set at.Join two hot boxes together you will get steam...but it gets dangerous. Fittings expand,pipes get soft/explode ,lance triggers get very very hot .

No ..they are good for hot water.Excellent for grease and speeds up most cleaning.
Real steam is a different thing but unless you are stripping paint or similar on a regular basis it a waste.

I fill the kids swimming pool up with hot water  ;D For pressure washing you only need 100 degrees as steam looses its mechanical action and you rely on the heat. I have a 15 ltr boiler and as Chris states it only really gets to 80 but thats why i now have a 21 ltr boiler and run it below 15 ltrs for gum. Its best to get the larger machine and run it at 3/4 capacity - I never ran the 15 ltr machine at anything other than flat out. Its not been out of the container since I built Wallace

I suppose that's the advantage of having a portable hot box  ;D, we use 21ltr very rarely use anymore than 10m hose between box to lance, reduce flow as stated achieve over 110 C use it even hotter for paint removal / spills.

On chewing gum jobs do you guys fsc with heat or stay cold and just use boiler for the gum itself.

Depends how bad the gum drop is, plus weather for me, if its really heavy use mosmatic with heat then spot, if its really cold weather just use cold then spot, surprising how much comes off with just cold.

Interesting read lads as i've just bought a lavor volcano hotbox (21ltr burner) hardley used from fleebay for £450 that I should get delivered mid week.

I've never used hot before so will be after some guidance on here aswell if you don't mind helping me out

Quick question for starters if you don't mind me asking is where is the best place to get decent hoses, lances and tips with the highest rated temp they do so to avoid any future issues using hot/steam.

Many thanks

Tbh smurf, your probably best off going to your local hydraulic shop for stuff like that. There a lot cheaper for hoses and connectors plus no p+p!


If I fsc cleaned cold first then gummed with hot would you see the lance marks from gumming? Reason I ask is that on my last job I did this and thought I could see lance marks so went over with again with hot fsc. I never took the change to let it dry to find out. I know its a question I could figure out on a future gum job but thought I'd ask while threads open.

In general no if it's clean its clean  ;) If its not clean then yes  :D

Cheers jettaway...

I've just see this vid and was just wondering what flow rate & psi the pump was set at also the temp of the boiler to get steam like that.

http://www.youtube.com/watch?v=7dJGuRF82-s

It says low flow & pressure but how low do you think and what temp is that?

Thanks... I've seen the spec of the kit but was just wondering if anyone knew what it would be set on to do delicate work like masonary cleaning as in the vid. Reason being I have a honda 15lpm 3000 psi gearbox driven interpump pressure washer that I'm guessing would be no good on jobs like that when using it with a lavor hotbox 21ltr as the flow rate and pressure would be still too high even if running the pump at low as I could.

What do you think?

 The flow rate will be between 2 and 5 litres per minute as for psi probably about 2000psi
better to remain silent and be thought a fool than to speak out and remove any doubt

Thanks Trevor as thought the flow would be very low.

Think I will now need to buy a suitable rated pump (prefered electric driven).  Can anyone recommend a decent one that is not going to cost silly money.

Can i just ask, why do you want to build something like the Thermowhatsit? Do you constantly do heritage rated restoration/cleaning? or do you do some gum removal, graffiti removal etc?

If you start to get into steam, as Chris pointed out, you need specialist hoses/guns/etc as the highest rated jetwas ones will melt, warp and blow.

I might be missing the point of your exercise here, but wont your hotbox, running with your current machine, be suitable for the work you do?

I'm trying to work out if I can put a system together myself instead of buying a really expensive bit of kit that probably would not be used much anyway.

Most of the time yes the kit that I have will do but on some delicate stuff I don't want to be blasting the cr"p out of it either if that makes sence.

This is pure steam - I wish you well on building your own - there's no debate on the nozzle temperature either, definitely 150 degrees Celsius
