If this is from a river, how fast does it flow, is there a fall across

It might be better to put a turbine in, generate electricity and use
that.

An idea, but to get a few 10's of kW of electricity you need a good
head and a hefty flow. IIRC 3kW of lecky needs a 20m head and 20l/sec
flow, if that is available it could drive the heatpump of course...
