As you can see in pictures I am trying to supply presoak, wax, tire cleaner mixing tanks with somewhat hot water. My concern is if the tankless that I purchased will do the job? BTW the tanks do not refill simultaneously, first presoak than tire cleaner then wax. Also this electric tankless water heater is rated @4GPM but I noticed that the outlet have a restricter in it (small hole in the outlet) and i was wondering if it'll have enough gpm/pressure to feed the mixing valve. The electrician and plumer will be here tomorrow to install it. Please advise if I am waisting $ on this project.
