Works great....advertised as a 8kw unit but pump specs are .22 which is for a 5kw unit. .28 is for an 8kw....and a .16 to .19 is a 2kw to 5kw unit. But switch out the pump and its what ever you want it to be. Emailed seller about a pump issue.....no reply. The unit is great and compact and works good.
