Running temps on hot water machines?

Good day all-

I have searched this topic pretty thoroughly and not come up with any great answers. What temps are you running for various applications when using “hot” water. What is hot? 130F? 200F?

The reason I’m asking is the general pumps TSF series can run up to 165F degrees input temps per manufacturers spec. Hot water burners made for pressure washers to run post pump seem to be comically expensive compared to an outdoor propane tankless water heater which could be plumbed on the input side of the pump and ran at temps within the manufacturers specs.

I appreciate that burner units can get hotter but I guess my question is how hot are you guys actually running them for commercial work on grease for surface work or other applications?

150F is pretty darn hot/third degree burn territory and within TSF pump specs. I’d be curious if guys who are regularly doing commercial/hot water work are typically running temps hotter than this?

If temperatures sub 165 are inadequate then so be it, the idea is a non-starter. I’m a bit surprised to not see any discussion of hot water on the input side with a rated pump anywhere on the forum.

Personally I’d be afraid to go into a put much over about 120 into my pump, which is about max I use for vinyl siding. But for popping gum and serious grease removal I routinely run 165-185. Average dirty commercial concrete you can get by with about 150.

What @Racer said, I use 110-115 on vinyl in the cooler season and 150-160 for commercial concrete stuff……

Sorry for butting in, but isn’t the pump before the burner?

a traditional high pressure burner, yes. the reason i was asking about temps is the general pumps tsf series are made for industrial applications like car washes where things like recycled hot water are being run through them, so they are designed to be run continually with up to 165F degree water input. an 8 gpm burner is like $3500 vs an 8 gpm tankless propane water heater is like $800.

so pay 3500 for an after the pump traditional burner that can run higher than 165 or like 1000 to still be able to get 150-160F degree water.

sounds like hotter than 150-160 would still be useful for gum removal and really heavy grease per @Racer

Buy once, cry once. Get the right tools the first time. Skip the propane heater.

Where you located?

@Racer Houston. @mwpws i get it, it was just an idea. seems like it is one of those ideas that could work but if you needed very hot water it wouldn’t quite cut it. just seemed like a clever entry level way to add some hot water cleaning power.

trust me its been contemplated already.
