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

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...


20l falling is giving (almost) 200N force, through 20m is 4Kj, that's
4Kw as you're doing it once a second. Seems possible.

But he's far more likely to have a lot more water and a lot less head if
the land is flat enough for agriculture.

Those of you factoring in the waste heat from lights, computers, etc.
might like to consider where that electricity comes from.


A nice little Nuclear power station not 50 miles from here..
