This one's aimed at the other pressure washing guys on here, - I've got a 21ltr hotbox similar to this..

What power generator would i need? I'm looking to buy one, but have no idea if 1kva,3.5kva is enough etc..

Any suggestions!?

There's no difference in power requirements between a 15 or 21, they have the same required power for the fuel pump, fan and switch.
1.5kva is more than enough.
We have a 2.2kva (5.5hp honda) and a 2.8kva (6.5hp honda)

When we have both burners running and the van and trailer are together hooked up we run both burners from any one of the generators. When they're apart we run one burner from each.

The difference between a 21 litre burner and a 15 is the length of coil therefore the 21 is a few inches taller.

Cheers Lee! - Dont forget to send me over that address please mate.

I've got me eye on a 3.5kva Honda jobby, hopefully get that one.

We run lights too for night work so it's big enough for that if you want to do the same.

Suitcase generators will run the burner but you could buy 2 maybe 3 generators on ebay for the price of one of those.

Will text you. It's confirmed.

I run mine on my 1 kva stephill suitcase on the snail setting - you could always use an inverter

I think it only draws about 300 watts including the clicker. Inverter plugged into the van?

Or the pressure washer battery if its leccy start
