I work for a heating company. Just left a car wash that has two wands at the entrance for pre soaking. The wands provide a soap and water mixture. Another company removed a boiler that heated this mixture and installed a on demand water heater that will not maintain hot water to the mixture. I am looking for help to restore this setup back to the correct working order. Thanks!

The tankless unit probably has enough BTU's to get the job done. I suspect the unit is cycling on and off constantly if it is feeding the guns directly. You're getting a cold water sandwich that brings the desired temp down.
You can use a 30 gallon storage tank and have the tankless unit feed the storage tank using a circulator pump and t-stat. Then take a line from another port on the storage tank to feed the pumps.
I use this setup to feed 2 self serve bays and 2 IBA's with a single Rainni, i don't remember the BTU's but it isn't very big.
