Home made hot tub

I have a home
made hot tub which basically consists of a 1500L fish tub which used to run off a Monaco lazy spa egg. The egg has now failed so I知 looking at converting it to be heated by a tankless water heater. I値l post pics.

can any advise on a pump I will need to feed the 18L tankless water heater? I want to draw the water out of the tub, through the heater and back into the tub.

Interesting that the photo says that the heater consumes 32kw of electricity and that it is LPG (liquid propane gas)??? And why are they stating a storage volume of water (18L) for something that is supposedly tankless? Those are red flags that you cannot trust it's specs and possibly it's poorly translated instructions so you will have to use your brain and figure out how to safely use it.

I recommend setting the heater at a very low temperature to minimize the chance of overheating the water.

Those heaters are only propane. They give the equivalent heat output in L.
You need a small hot water circulator pump like..... Taco circulator pump
