Wondering what systems people are using for higher gpm, hot water? I'm talking 6gpm and higher. Whose making burners that can keep up with the flow. I've seen the Pressure wash store: 8gpm

Is the heater coil/burner different from the common 4-5gpm machines? What other manufacturers are making higher gpm skids and burner set ups? Looking forward to the next step in my equipment arsenal! Thanks
 
How high you want to go exactly?

All the burners you pretty much see for sale between envirospec to powerwashstore are pretty much max 8 gpm. They all have a flow switch that are 8 gpm max and so I would not hope for too much more then 8 gpm.

honestly if you are doing over 8 gpm you are looking at a custom burner which is big money, or 2-3 burners depending on your gpm from a standard burner.

Ok, good to know. I wasnt thinking anything over 8-10 gpm. I just want a machine that will fly surface cleaning. Curious what is out there.

Which surface cleaner are you pushing?

Are you looking for just the boiler or the whole skid? The burners go up in size but become very heavy fast and also the extra length of the coil - around 300 ft! in a big coil - adds back pressure. If you know how hot you need to go you may be able to up the heat with a bigger head/blower, nozzle size and higher fuel pressure on a smaller boiler.

Yes. But boilers are very finicky and sensitive. There is probably some room to get some more fuel and air going in most, it's a matter of trial and error. But, the size of the combustion chamber ultimately limits how much.
 
Landa makes skids that big.

So I will say that if a guy was going to attempt this he had better study up on the subject and have someone to call just in case there is trouble. Wouldn't it be a good idea to install some type of relief valve as well Tom?
 
My current setup uses 2 smaller burners. It seems to work much better then one large burner. With my large burner the temp fluctuated greatly. With the 2 small burners it keeps it right at the sweet spot....just below the steam point.
