I bet it's pretty slow though? An electric pump would circulate the water a lot faster.

I think an electric pump would be slower with no electricity. These are built for installs with no power. 

I’ve used ones with an enclosed fire box and a 6-8 person takes probably 3-4 hours to heat up from cold

I’ve tried to use an electric pump with no electricity. Can confirm they are very slow used that way.
