Tankless HW heater for a WW Razor

[lighthousecarwash]

I'm going to be installing a new Razor and would like to put a dedicated tankless water heater for the heated solutions. Has anyone done this and what brand and size is required. WW indicated that it would only use around 2 gallons for each pass, which shouldn't require a very large unit in my opinion.

Thanks

I use a tankless Takagi water heater with my razor to heat the presoak. It works great. I don't recall what size I put it without looking at it.

do you need hot water for the Wash World?

I heat all my water that touches chemicals. I would hate to see how bad any of the automatics would clean without hot presoak.
